Other reasons for removal may be cosmetic or because a raised mole interferes with daily life (e.g., shaving). If a melanocytic nevus is suspected of being a melanoma, it needs to be sampled or removed via skin biopsy, and sent for microscopic evaluation by a pathologist. Depending on the size and location of the original nevus, a complete ...
The International Classification of Diseases for Oncology (ICD-O) is a domain-specific extension of the International Statistical Classification of Diseases and Related Health Problems for tumor diseases. This classification is widely used by cancer registries. It is currently in its third revision (ICD-O-3). ICD-10 includes a list of ...
Pseudomelanoma (also known as a "recurrent melanocytic nevus", [1] and "recurrent nevus" [2]) is a cutaneous condition in which melanotic skin lesions clinically resemble a superficial spreading melanoma at the site of a recent shave removal of a melanocytic nevus. [2]: 689
However, a melanocytic nevus is benign, and melanoma is malignant. Most melanocytic nevi never evolve into a cancer, with the lifetime risk for an individual nevus being 1 in 3000 for men and 1 in 11 000 for women. [5] Moreover, dermatologists have a standardized system for determining whether a skin lesion is suspicious for malignant melanoma.
In 1992, the NIH recommended that the term "dysplastic nevus" be avoided in favor of the term "atypical mole". [1] An atypical mole may also be referred to as an atypical melanocytic nevus, [2] atypical nevus, B-K mole, Clark's nevus, dysplastic melanocytic nevus, or nevus with architectural disorder. [3]
A related category of melanocytic proliferation is superficial atypical melanocytic proliferations of uncertain significance (SAMPUS). This category, unlike MELTUMP, which implies as yet undetermined potential for metastases even after complete excision, signifies lesions without metastatic potential at time of excision but with potential to ...
A melanocytoma is a rare pigmented tumor that has been described as a variant of the melanocytic nevus [1] and is derived from the neural crest. [2] The term "melanocytoma" was introduced by Limas and Tio in 1972.
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]).
