| epidermic-dermic nevus | A nevus consisting of nests of melanocytes in the basal cell zone, at the junction of the epidermis and dermis, appearing as a slightly raised, small, flat, nonhairy pigmented (brown or black) tumour. Synonym: epidermic-dermic nevus. (05 Mar 2000) |
| epithelioid cell nevus | A benign, slightly pigmented or red superficial small skin tumour composed of spindle-shaped, epithelioid, and multinucleated cells that may appear atypical; most common in children, but also appearing in adults. Synonym: benign juvenile melanoma, epithelioid cell nevus, spindle cell nevus. (05 Mar 2000) |
| Jadassohn's nevus | Congenital papillary acanthosis of the epidermis, with hyperplasia of sebaceous glands developing at puberty and presence of apocrine glands in non-apocrine areas of the skin (commonly the scalp).

Synonym: linear epidermal nevus. (05 Mar 2000) |
