Nevus

Moles are growths on the skin. They happen when pigment cells in the skin, called melanocytes, grow in clusters. Moles are very common. Most people have between 10 and 40 moles. A person may develop new moles from time to time, usually until about age 40. In older people, they tend to fade away. Moles are usually pink, tan or brown. They can be flat or raised. They are usually round or oval and no larger than a pencil eraser. About one out of every ten people has at least one unusual (or atypical) mole that looks different from an ordinary mole. They are called dysplastic nevi. They may be more likely than ordinary moles to develop into melanoma, a type of skin cancer. You should have a health care professional check your moles if they look unusual, grow larger, change in color or outline, or in any other way. NIH: National Cancer Institute.  [from MedlinePlus]

Becker Nevus

A benign lesion that is sometimes congenital and consists of an overgrowth of the epidermis and the presence of melanin-containing cells. It is found mostly in males and typically develops during childhood or adolescence, becoming darker and more hairy after puberty. [from NCI]

Epidermal nevus

Epidermal nevi are congenital lesions that affect about 1 in 1,000 people. They appear at or shortly after birth as localized epidermal thickening with hyperpigmentation that frequently follow the lines of Blaschko, suggesting that they result from postzygotic somatic mutation in the skin (Paller et al., 1994). A rare subgroup of epidermal nevi is clinically indistinguishable from other epidermal nevi, but displays histopathologic features typical of epidermolytic hyperkeratosis (see EHK, 113800), and patients with this type of epidermal nevi sometimes have offspring with generalized EHK (Paller et al., 1994). See giant pigmented hairy nevus (137550) and malignant melanoma (155600). Nevus sebaceous is a benign congenital skin lesion that preferentially affects the scalp and face. It occurs in about 1 in 1,000 live births and is characterized by hairless, yellow-orange plaques of various size and shape. Histology shows that nevus sebaceous is a hamartoma consisting of epidermal, sebaceous, and apocrine elements. About 24% of nevi develop secondary tumors, some of which may be malignant (summary by Groesser et al., 2012). [from OMIM]
