<unk>  nevi may be divided into the following types: * A patch<unk>  (also known as an "acquired dermal melanocytosis", and "dermal melanocyte hamartoma") is a cutaneous condition characterized by a diffusely gray-blue area that may have superimposed darker macules. * A<unk>  of Jadassohn–Tièche (also known as a "common<unk> ", and "nevus ceruleus") is a cutaneous condition characterized by a steel-blue papule or nodule. * A cellular<unk>  is a cutaneous condition characterized by large, firm,<unk>  or<unk> -black nodules. * An epithelioid<unk>  is a cutaneous condition most commonly seen in patients with the Carney complex. * A deep penetrating nevus is a type of benign melanocytic skin tumor characterized, as its name suggests, by penetration into the deep dermis and/or subcutis. Smudged chromatic is a typical finding. In some cases mitotic figures or atypical melanocytic cytology are seen, potentially mimicking a malignant melanoma. Evaluation by an expert skin pathologist is advisable in some cases to help differentiate from invasive melanoma. * An amelanotic<unk>  (also known as a "hypomelanotic<unk> ") is a cutaneous condition characterized by mild atypia and pleomorphism. * A malignant<unk>  is a cutaneous condition characterized by a sheet-like growth pattern, mitoses, necrosis, and cellular atypia.<unk>  - intermed mag.Micrograph of a<unk>  showing the characteristic pigmented melanocytes between bundles of collagen.
