Management If the diagnosis of junctional naevus is clear and there has been no change in a long-standing lesion then reassurance and monitoring of the lesion are all that is usually required. Where there is any doubt as to the diagnosis, perform excision biopsy or refer for dermatological advice The junctional nevus is composed of discrete nests of melanocytes/nevus cells at the dermoepidermal junction, usually located on the rete ridges, which often show some accentuation. The cells are oval to cuboidal in shape, with clear cytoplasm containing a variable amount of melanin pigment. Mitoses are rare or absent A junctional melanocytic nevus is most likely an atypical or dysplastic nevus. These are not melanoma but do have some atypical cells or architecture. Depending on how atypical they are, extra margins are usually taken. I'm not sure the protocol in the UK but if the lesion were considered severely atypical, they may take up to 5mm margins
Acral lentiginous melanoma is a clinicopathologic entity with a clear-cut clinical picture: a diameter larger than 0.7 mm; ill-defined, darkly pigmented, flat lesion with irregular borders on acral locations; and the presence of mostly single-cell proliferations of melanocytes along the dermo-epider Every person has a number of junctional nevus. If a junctional nevus, or any mole, show signs associated with possible malignant change, it should always be checked by a doctor. When a malignant melanoma is suspected, the usual treatment is to cut the mole out completely before examining it under a microscope Microscopic (histologic) description. Rounded nests of melanocytes / nevus cells on epidermal side of dermoepidermal junction, originating from tips of rete ridges. Variable lentiginous melanocytic hyperplasia In majority of the cases where an individual has a melanocytic nevus, there is no treatment required. However, there are few cases in which this melanocytic nevus marks need to be removed. A disorder of melanocytes is caused when cells that are responsible for producing melanin result in the development of melanocytic nevus Every day, in every dermatologist's office, there is a discussion with patients about whether to re-excise their biopsied atypical nevus (AN, aka dysplastic nevus, Clark nevus, nevus with architectural disorder) that extended to the margin. The most recent literature suggests that cases of mild and moderate AN, with microscopically positive margins and no concerning clinical residual lesion.
A junctional nevus will typically evolve over time into a compound nevus, which is a nevus with both epidermal and dermal melanocytes. Compound nevi become elevated and usually are more pale. Junctional nevi will typically grow to be 3 or 4 mm across, stop growing sideways, and begin to evolve into a compound nevus Junctional melanocytic nevus composed of small nests of melanocytes and lentiginous melanocytic proliferation at the dermal-epidermal junction (hematoxylin-eosin stain, original magnification X100). Compound melanocytic nevus with nests of uniform melanocytes in the epidermis and the dermis (hematoxylin-eosin stain, original magnification X200) Medical Care. Medical treatment is typically ineffective and inappropriate for the management of a benign neoplasm such as a melanocytic nevus. Next: Surgical Care. Surgical Care. Melanocytic nevi can be surgically removed for cosmetic considerations or because of concern regarding the biological potential of a lesion
No treatment is required unless the patient is concerned about the lesion's cosmetic appearance or there are suspicions of an alternative diagnosis. Excision biopsy may be used for diagnostic purposes The diagnosis of atypical lentiginous melanocytic naevi in chronic sun-damaged skin is a clinical and pathological challenge. Mottled skin in the elderly is a result of extensive freckling, guttate hypomelanosis, solar lentigines, seborrhoeic keratoses and small dark lentigines. In addition, atypica
The histological term, junctional melanocytic hyperplasia (JMH), refers to the proliferation of single melanocytes along the dermal epidermal junction that is the basal layer where normal melanocytes reside. JMH is characteristic of lentigo simplex, junctional nevus, and dysplastic nevus A Spitz naevus (or Spitz's nevus) is an uncommon type of mole ( melanocytic naevus). A Spitz naevus is a benign skin tumour. However, it may resemble a melanoma clinically and microscopically, so Spitz naevi are often excised as a precaution. Spitz naevi. Classic Spitz naevus Atypical Nevus • 1. Architectural disorder - Shouldering -proliferation of junctional nests of melanocytes extending beyond the dermal component - Intraepidermal lentiginous hyperplasia of melanocytes - Proliferation of melanocytes singly and in nests along the basal layer (sides and tips of rete ridges) • 2. Cytological atypi One can do a complete excisional skin biopsy or a punch skin biopsy, depending on the size and location of the original nevus. Other reasons for removal may be cosmetic, or because a raised mole interferes with daily life (e.g. shaving). Removal can be by excisional biopsy or by shaving
junctional nevus removal A member asked: i had a shave removal that came back as lentiginous junctional (dysplastic) nevus with mild atypia, to <0.2 mm of. is this of concern Treatment: The patient elected to have the entire lesion removed, rather than to undergo a biopsy. The macule proved to be a severely dysplastic junctional nevus. Because the lesion was already excised with a conservative margin of 5 mm of clear skin, treatment was considered sufficient Nevus pigmentosus occurring in palmar, plantar, labial, and genital areas are almost all junctional nevus, where can be regarded as predilection sites. Junctional nevus is characterized by flat or slightly elevated, round or oval, light brown to dark, 1 - 8mm in diameter pigmented spots or pimples, with smooth surface, without hairs A nevus (plural nevi) is a mole on the skin that can occur on any part of the body. A common mole is benign tumor of melanocytic (pigment-based) cells that occur on the skin. It is also known as acquired melanocytic nevus. Normally, Junctional Common Moles (or simply Junctional Moles) are present in all individuals including children and adults
Risk factors for the development of AMN include fair skin type (often with red hair, blue eyes, and inability to tan), propensity to sunburn, freckling, and sun exposure. 2 Acquired melanocytic nevi may be flat (junctional melanocytic nevus) or raised (compound and dermal melanocytic nevus) and are usually less then 6mm in diameter. AMN are. Question: I had two nevi removed and the diagonsis is junctional nevi with pigment incontinence and lichenoid inflammation what does that mean? i am not sure if that is something to worry about.the diagnosis for another nevus is atypical compound nevus with moderate cytologic and mild architectural disorder... the lab recommended re-excision and my doctor did so. the lab assumed shave. junctional melanocytic nevus, dysplastic type with severe atypia You could get a second opinion if you want, but the actual treatment would not change. I, personally, wouldn't go there. As with any lesion that is removed, monitor the scar area for any pigment regrowth. If you have pigment growing back in the scar, see your derm •Nevus > dysplastic nevus > melanoma in-situ/invasive melanoma •Precisely analogous to cervical dysplasia and senile keratosis: foci of squamous cells have some of the structural features of malignancy, but may remain indolent, regress completely , or progress to obvious carcinoma •Cervical dysplasia What is Lentiginous junctional nevus? The term lentiginous junctional nevus is used for junctional nevi in which the epidermis has lentigo-like features with elongated and pigmented epidermal rete ridges. In lentiginous nevi, there is typically a proliferation of solitary units and nests. Click to see full answer
Clark et al 1 described the atypical, or dysplastic, nevus as having unusual clinical and pathologic features found in individuals or families predisposed to melanoma. A National Institutes of Health Consensus Conference 2 further defined atypical nevi as having diameter greater than 5 mm, color or border irregularity, and certain histologic features. . Evidence supports observations that the. Nevus (plural: nevi) is the medical term for a mole. Nevi are very common. Most people have between 10 and 40. Common nevi are harmless collections of colored cells. They typically appear as small. A microscopically dysplastic nevus may be either junctional or compound. In general, a junctional DN consists of a proliferation of a variable combination of single and nested melanocytes along the dermal-epidermal junction with a host response, architectural typia and cytologic atypia as defined above
Conversely, a junctional nevus, which develops at the junction of the dermis and epidermis, is potentially cancerous. Just so, what is junctional nevus? A junctional nevus is a mole that occurs between two layers of skin. This image shows two junctional nevi that appear as uniformly brown small macules, round in shape with smooth regular borders .
Spitz nevus treatment. In children under the age of 12 years, a Spitz nevus may be kept under review using digital dermatoscopic surveillance (monitoring photographs of the lesion's dermatoscopic appearance). Junctional nevus: A junctional nevus has groups or nests of nevus cells at the junction of the epidermis and the dermis. A flat mole Junctional nevi are most commonly found in children. Junction nevi vary in size from 0.1 to 0.6 cm; some are larger. They appear as flat or slightly raised brown to tan macules with uniform pigmentation that may be slightly irregular. The surface is smooth and flat to slightly elevated, and the border is round or oval and symmetric Diagnosis. Treatment. Outlook. A Spitz nevus is a type of rare, non-cancerous skin growth that typically impacts people under 35 years old. Spitz nevus growths, or Spitz nevi, were once considered. Giant pigmented nevus: Diameter larger than 20 cm; frequently covers large areas of the body in a garment-like fashion. The trunk, head and neck are the most common sites. Junctional nevus: Smooth, hairless, light to dark brown mole. Can be slightly elevated, usually multiple and can occur on any part of the body Junctional nevus can be macular or thinly papular and it is most likely to be just minimally elevated from the level of the skin. With age, junctional nevus may change and become compound nevus, characterized by accumulated melanocytes in deeper layer of the skin (dermis) and also at the dermo-epidermal junction
Nevus spilus is characterized by numerous small, darkly pigmented macules or papules on a tan-pigmented background. This lesion is also referred as speckled lentiginous nevus, zosteriform lentiginous nevus, or spotty nevus [1, 2].It can be a junctional nevus, compound nevus, Spitz nevus, or blue nevus .The lesions are usually located on the trunk, extremities, or following. Facial malignant melanoma occurs on the basis of pigmented nevus, often forming large nevus cells of junctional nevus or compound nevus with malignant transformation. When the nevi are affected by chronic infection, injury, and other undesirable stimulation or improper treatment of pigmented nevus, parts of nevi are transformed to malignant.
Conjunctival nevus is a benign, noncancerous growth and is the most common lesion that occurs on the surface of the eye. It is usually a discrete lesion on the conjunctiva (the clear film over the eye) and can range from dark brown to yellow color, and many times will contain clear cystic components. These lesions can darken or lighten with time Microscopic (histologic) description. Shoulder area of lentiginous junctional melanocytic proliferation beyond lateral border of underlying dermal nevus. Elongation of rete ridges with small nests of melanocytes at tips of rete. Individual unit melanocytes extending along sides of rete, often mild lymphohistiocytic infiltrate with pigment. Treatment of Clark's Nevus. There are some different types of treatment for Clark's Nevus that are available. People with this form of nevi should be routinely evaluated by a dermatologist once or twice each year, and use sunscreen on exposed areas of their skin. The one safe way to remove any atypical mole is to have it cut out
junctional nevus Pronunciation: (JUNK-shuh-nul NEE-vus) A type of nevus (mole) found at the junction (border) between the epidermis (outer) and the dermis (inner) layers of the skin It came back compound nevus with mild junctional atypia. There was a note below the diagnosis that said part of the atypia may be reactive, however, clinical follow up is recommended. My dermatologist is sending me to a plastic surgeon to have it removed. Is this necessary. What are the chances this is cancerous or could become cancerous . Junctional tachycardia is an unusually fast heart rhythm originating around the atrioventricular (AV) junction, a structure between the atria and ventricles of the heart that houses the AV node, an important part of the heart's natural pacemaker system The nevus spilus may be mistaken for a café-au-lait spot, congenital nevus, or lentigo. Biopsy may reveal the small internal hyperpigmented macules and papules to be lentigines, junctional or compound nevi, spindle cell nevi, blue nevi, dyplastic nevi, or melanoma. Histological feature
A junctional nevus is a mole that is found in between the outermost layer ( epidermis) and underlying layer (dermis) of skin. This picture shows two junctional nevi. They are brown, round, flat spots (macules) that have regular borders. Image Source: Color Atlas & Synopsis of Pediatric Dermatology Kay Shou-Mei Kane, Jen Bissonette Ryder. A dysplastic nevus, occasionally called a Clark's nevus, is an abnormal mole. They can occur at any age and anywhere on the skin. Dysplastic nevi are usually tan, brown, or dark brown in color. They are often wider than an eraser head of a pencil and regularly have indistinct borders Compound Melanocytic Nevus . Compound Nevi. Key points. Compound Nevi are a sub-class of Common Acquired Melanocytic Nevi ; Typically they are light tan to dark brown, dome shaped papules that are 1-10 mm in diameter. Compound Nevi are benign proliferations of melanocytes at the epidermal-dermal junction
Spitz tumor (nevus) is a rare, melanocytic lesion that primarily affects children and adolescents. The lesion may share many clinical and histological similarities with malignant melanoma and careful microscopic examination is required to render the proper diagnosis. Complete excision with close follow-up is considered the appropriate treatment. Junctional melanocytic nevi are common. Furthermore, surgical treatment of these nevi can be challenging due to scar formation. Aims. The study aims to detect the efficacy and safety of the CO 2 fractional laser for treating acquired junctional melanocytic nevi and usefulness of dermatoscopy for the monitoring of the nevus. Method
Atypical nevi, also known as dysplastic nevi, are benign acquired melanocytic neoplasms. Atypical nevi share some of the clinical features of melanoma, such as asymmetry, irregular borders, multiple colors, and diameter >5 mm ( picture 1A ). They occur sporadically or in a familial setting junctional nevus: [ ne´vus ] (pl. ne´vi ) ( L. ) a circumscribed stable malformation of the skin or sometimes the oral mucosa, which is not due to external causes; the excess (or deficiency) of tissue may involve epidermal, connective tissue, adnexal, nervous, or vascular elements. Most are either brown, black, or pink; they may appear on any.
Spitz nevus. Spitz nevus, also known as spindle and epithelioid cell nevus, is a benign melanocytic neoplasm seen predominantly in children and adolescents, although they may also develop in adults. Sophie Spitz first described these nevi as benign juvenile melanomas on the basis of their histologic resemblance to melanoma, but having a. NCI's Dictionary of Cancer Terms provides easy-to-understand definitions for words and phrases related to cancer and medicine A dysplastic nevus before laser treatment (A); immediately following 1 treatment of the upper half of the nevus with the Q-switched ruby laser, 7.5 J/cm 2, 5-mm spot size (B); and 2 weeks following treatment (C).A whitening effect is seen on the treated upper half of the lesion Melanocytic Nevus Treatment. Once a patient is diagnosed, the next step is remove the abnormal mole. Surgery, where a wide, local incision is made can result in a high risk of the lesion returning, but it is the most widely used treatment option. Once the lesion is removed, it should be submitted for microscopic evaluation Nevus cells evolve from the epidermis into the dermis, so the junctional nevus is common in children, and intradermal nevus is common in adults . Most dome-shaped and papillomatous nevi are found in intradermal nevi . Most melanocytic nevi are benign, and treatment is not necessary if they are asymptomatic [3, 5]
Mole, not cancer: Here is a translation of your path report: Junctional- location as it relates to depth in the skin, the junction between epidermis and dermis. lentiginous- means flat dark spot, melanocytic- made up of pigment cells (melanocytes), nevus - a lesion that contains nevus cells a type of melanocyte, aka mole. This is a benign spot that appears to have been completely removed The melanocytes in a compound nevus are found in both the epidermis and the dermis below. The melanocytes form groups called nests although single cells may also be seen. Most compound nevi develop from a very similar growth called a junctional nevus. In a junctional nevus, the melanocytes are only found in the epidermis Reed nevus (also known as pigmented spindle cell nevus of Reed) is an acquired, benign, melanocytic lesion most frequently classified as a variant of a Spitz nevus. A Reed nevus typically presents as an asymptomatic, single, 2-8 mm, dark brown to black macule or papule on the lower extremities of young adults Over time the nevus transforms into a compound nevus - the nevus cells have extended from the junctional zone down into the dermis that gives it elevation. As the patient ages, the nevus loses its epidermal pigmentation and remains as an elevated, minimally pigmented or amelanotic lesion
November 28, 2011. Answer: Moles. Melanotic hyperplasia means there is an increase in the number of malanocytes (The cells that contain the pigment , melanin). It is not as atypical mole. If the melanocytic hyperplasia extends to the margin, it should be excised, just for safety Benign junctional nevus Detailed Answer: Hi. I don't agree with it being darker due to a hair follicle. It is just that it is little darker in the center than at the periphery probably because the pigment is more superficially located in the center part than at the periphery. It is a benign junctional nevus
The smaller and thinner lesions (junctional nevus) are typically more treatment-sensitive. 30,32 With deeper lesions (compound and dermal nevus), complete eradication is much more difficult, and recurrence is common. 30,32 Laser therapy decreases the number of the pigmented nevomelanocytic cells in the papillary dermis, but is unlikely to treat. Treatment, prognosis and preventional measures References Abstract Atypical moles (Ams) represent a commonly acquired activated junctional nevus. There are fairly common with onset near puberty and they remain dynamic throughout adulthood. They rarely progress t
BackgroundThe role of neoadjuvant chemoradiotherapy in the treatment of patients with esophageal or esophagogastric-junction cancer is not well established. We compared chemoradiotherapy followed b.. In junctional nevi nested proliferations of melanocytes are located in the basal epidermis and extend into the tips of the rete ridges. Compound nevi have both a nested junctional location and an intradermal component. The intradermal nevus is confined to the dermis without any junctional component A dysplastic nevus is a type of mole that looks different from a common mole. (Some doctors use the term atypical mole to refer to a dysplastic nevus.) A dysplastic nevus may be bigger than a common mole, and its color, surface, and border may be different. It is usually more than 5 millimeters wide (1, 3). A dysplastic nevus can have a.
Spitz nevus (Epithelioid and Spindle-Cell Nevus) is an uncommon, benign, melanocytic nevus that is usually acquired and has histologic features that overlap with those of melanoma.Spitz nevi were previously diagnosed as melanomas due to their similar appearance under a microscope, until it was found that they did not show malignant behavior It states, Within a small circumscribed area there are junctional melanocytes nests. Mononuclear inflammation and melanophages are present in the subjacent dermis. I interpret this as a markedly inflamed junctional melanocytic nevus but since this nevus extends close to a margin conservative re-excision is suggested to ensure complete removal. Nevus (or naevus) is a general term that refers to a number of different, usually benign, pigmented lesions of the skin. Most birthmarks and moles fall into the category of nevi. The nevus cells make the nevus. The great majority of moles are harmless, but in rare cases, moles may become cancerous. Homeopathic Treatment of Moles/Naevi What exactly does this mean: junctional melanocytic nevus with atypical lentiginous hyperplasia, irritated, the - Answered by a verified Dermatologist. and the dermatologist called to let me know that everything is benign and no further treatment is necessary. However, the biopsy report got me worried This junctional melanocytic nevus is an oval macule of even, light brown pigment. There is overall symmetry with a smooth border; the size was measured to be 2 × 1 mm. This junctional melanocytic nevus shows nests at the tips and sides of rete ridges. The presence of pigmented parakeratosis and pigment incontinence likely corresponds to a dark.
Atypical moles, also known as dysplastic nevi, are unusual-looking moles that have irregular features under the microscope. Though benign, they are worth more of your attention because individuals with atypical moles are at increased risk for melanoma, a dangerous skin cancer.. An atypical mole can occur anywhere on the body The common mole or acquired melanocytic nevus (AMN) is a collection of nevomelanocytes grouped into nests located in the epidermis (junctional nevus), dermis (dermal nevus), or both (compound nevus). It is hypothesized that nevomelanocytes are derived from either epidermal melanoblasts or dermal Schwann cells
Benign junctional melanocytic nevus. Benign neoplasms of the skin which contain melanocytes are called melanocytic nevi. Melanocytes are cells responsible for production of the skin pigment and they are located in the outer layer of the skin - epidermis. Besides the humans, dogs and horses are also very frequently found to develop melanocytic. A congenital nevus, also known as a mole, is a type of pigmented birthmark that appears at birth or during a baby's first year. These occur in 1% to 2% of the population. These moles are frequently found on the trunk or limbs, although they can appear anywhere on the body. Most congenital nevi usually do not cause health problems, but a small.
A, nevus, compound type, with architectural disorder and mild cytologic atypia of melanocytes.This region shows the extension of the junctional component beyond the dermal component, with some. The junctional nevus cells are epithelioid and may exhibit cytologic atypia, such as nuclear enlargement and nucleolar prominence. Hyperchromatism is sometimes a feature. Cytologic atypia, if present, is usually seen only in a subpopulation of cells. When it involves a large fraction of melanocytes, concern for melanoma should be raised A nevus (pl. nevi), or mole, is a benign growth comprised of aggregates of pigment producing cells. They vary greatly in appearance, size, pigmentation, and surface characteristics. However, each individual nevus is uniform in border, color, and texture, distinguishing it from a malignant melanoma. There are three types of nevi: junctional. Junctional scotoma and the junctional scotoma of Traquair are visual field defects that arise from damage to the junction of the optic nerve and the optic chiasm. Sellar masses including pituitary tumors are the most common cause of these visual field defects. Ophthalmologic findings include ipsilateral central scotoma and contralateral superior temporal quadrantanopia (junctional scotoma, JS.
The word atypical means not like the rest.. Nevus is the medical term for melanoma, the deadliest type of skin cancer. But an atypical mole is not melanoma or any other type of skin cancer. An atypical mole is benign (not cancer). A dermatologist may refer to an atypical mole as a dysplastic nevus. Regardless of the term, these moles are. TREATMENT:It should be excised and submitted tohistopathological examination. Onceexcised, a junctional nevus does nottend to recur. 13. COMPOUND NEVUS: 14. • It has the combined characteristics of the intramucosal nevus and junctional nevus.• Exhibiting nevus cells in the basal region of the epithelium and the adjacent connective tissue Moles are flesh- to brown-colored macules, papules, or nodules composed of nests of melanocytes or nevus cells. Moles develop on nearly everybody, and are significant primarily because they can become dysplastic or malignant and need to be differentiated from melanoma. Image provided by Thomas Habif, MD. Junctional Nevi Nevus/Nevi. Nevi (singular nevus), also known as moles, are benign neoplasms of the skin. Nevus is a non-specific medical term because it encompasses both congenital and acquired lesions, hyper- and hypopigmented lesions, and raised or flat lesions. Additionally, nevi can be found within different depths of the layers of the skin and. Lack of the typical vertically oriented fascicles of nevus cells in nests at the dermo-epidermal junction and in the papillary dermis in a raining down or bunch of bananas pattern Increased mitotic activity in the lower one third of the neoplasms and increased percentage of melanocytes staining with Ki-67 (Specimen #1 and 2
This is a junctional nevus, meaning that it is at the junction of the dermis and the epidermis. Junctional nevi have pigment regularity and are flat or slightly raised. This category 1 compound. The cause of melanocytic naevi is unknown; Melanocytic naevi have historically been classified by their histological appearance as being junctional (focal proliferation of melanocytes at the dermal-epidermal junction), compound (a combination of junctional activity and intradermal naevus cells) and intradermal (groups of mature naevus cells in the dermis only) Dysplastic Junctional lentiginous nevus Background: A controversy in the treatment of melanoma in situ is the required width of surgical margin. The currently accepted 5-mm margin is based on a 1992 consensus opinion, despite data since then showing this is inadequate Treatment of Divided Eyelid Nevus With Orbicularis Oculi Myocutaneous Flap: Report of 17 Cases. Liu J, Sun J, Wang Z, Guo L, Guo N Ann Plast Surg 2020 Dec;85(6):626-630. doi: 10.1097/SAP.0000000000002507 Deep penetrating nevus is a benign melanocytic proliferation. On the basis of a review of the literature of more than 300 DPNs published to date, just 3 local recurrences after incomplete excision have been reported. 5, 8 Conservative and complete local excision appears to be the best treatment option for DPN
Deep penetrating nevus (DPN) is a distinct variant of melanocytic nevus and remains a histopathologic challenge to pathologists because of its resemblance to blue nevus, malignant melanoma, pigmented Spitz nevus, and congenital melanocytic nevus. It often goes unrecognized due to its relative rarity. Here we report a case of DPN of the left anterior leg in a 51-year old female Cellular blue nevus is a blue-gray nodule or plaque 1 to 3 cm diameter mostly located on the buttock or sacrum. Combined blue nevus-melanocytic nevus, sometimes confused with atypical nevi or melanoma. Malignant blue nevus, may develop in contiguity with cellular blue nevus, nevus of Ota, or de novo [ 18 ]. 2.6 Dysplastic nevus was defined based on the criteria of the Europe Organization for Research and Treatment of Cancer . Specifically, a DN should fulfill at least three of the following four criteria: obvious hyperplasia of nevus cells in the basal layer, irregular nests of nevus cells, nevus cells with a large nucleolus, and nevus cells with. Both melanocytes and nevus cells are capable of producing the pigment melanin. Melanocytic nevi can be congenital or acquired. Congenital melanocytic nevi (CMN) are classically defined as melanocytic nevi present at birth or within the first few months of life. CMN and speckled lentiginous nevi (a subtype of CMN) will be discussed below
This lesion is a congenital nevomelanocytic nevus. This common hamartoma of the skin is composed of nevocytes that may be present in the dermal-epidermal junction (junctional nevus), in the dermis only (intradermal nevus), or in the junction as well as the dermis (compound nevus). Congenital nevomelanocytic nevi are present either at birth or. A dysplastic nevus or atypical mole is a nevus (mole) whose appearance is different from that of common moles. In 1992, the NIH recommended that the term dysplastic nevus be avoided in favor of the term atypical mole. An atypical mole may also be referred to as an atypical melanocytic nevus, atypical nevus, B-K mole, Clark's nevus, dysplastic melanocytic nevus, or nevus with architectural. If these melanocytes are localized to this junction, it is called a junctional nevus. With time, the nests of melanocytes may descend into the underlying dermis and is termed a compound nevus . In older lesions, the melanocytic nests completely descend into the dermis without any junctional nests and is termed a dermal nevus
