A Spitz nevus is a benign skin lesion.A type of melanocytic nevus, it affects the epidermis and dermis. [1]It is also known as an epithelioid and spindle-cell nevus, [2] and misleadingly as a benign juvenile melanoma, [2]: 691 and Spitz's juvenile melanoma [3]).
Several lesion types may be classified as MELTUMPs: these include atypical melanocytic proliferations with features that may overlap with atypical Spitz naevi/tumors, dysplastic naevi, pigmented epithelioid melanocytoma, deep penetrating naevi, congenital naevi, cellular nodules in congenital naevi, possible naevoid melanomas, and cellular blue ...

Melanoma with features of a Spitz nevus, also known as a Spitzoid melanoma, is a cutaneous condition characterized histologically with tissue similar to a spitz nevus and with overall symmetry and a dermal nodule of epithelioid melanocytes that do not mature with progressively deeper dermal extension.
Epithelioid cells gather around the focus of necrosis, in direct contact with the necrotic masses, forming a kind of boundary zone.. Structurally, epithelioid cells (when examined by light microscopy after stained with hematoxylin and eosin), are elongated, with finely granular, pale eosinophilic (pink) cytoplasm, and central, ovoid nuclei (oval or elongate), which are less dense than that of ...
An epithelioid blue nevus is a cutaneous condition most commonly seen in patients with the Carney complex. [7]: 701 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.
Melanoma is the most dangerous type of skin cancer; it develops from the melanin-producing cells known as melanocytes. [1] It typically occurs in the skin, ...
Although a nevus and a melanoma are often treated as independent entities, there is evidence that a nevus can be a precursor for a melanoma. [1] Common mutations have been identified in nevi and melanomas. [2] [3] [4]
