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 ...
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.
The features include: 1) two or more clinically atypical nevi, 2) more than 100 nevi in patients between 20 and 50 years of age, 3) more than 50 nevi in patients under 20 years of age or more than 50 years of age, 4) more than one nevus in buttocks or instep, 5) nevi on the anterior scalp, 6) one or more pigmented lesions in the iris.
Treatment is dependent on the specific type of cancer, location of the cancer, age of the person, and whether the cancer is primary or a recurrence. For a small basal-cell cancer in a young person, the treatment with the best cure rate (Mohs surgery or CCPDMA) might be indicated. In the case of an elderly frail man with multiple complicating ...
Patients with non-giant congenital melanocytic nevi seem to have a much lower, but undefined risk. Of these patients, only a small number are symptomatic, usually displaying symptoms before the age of 2. [6] These symptoms are the result of melanocytic lesions being present in the leptomeninges of the central nervous system. [3] Symptoms can ...
Inherited dysplastic nevus syndrome is an autosomal dominant hereditary condition. Dysplastic nevi are more likely to undergo malignant transformation when they occur among members of melanoma families. At least one study indicates a cumulative lifetime risk of nearly 100% in individuals who have dysplastic nevi and are members of melanoma ...
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.
Balloon cell nevus is a benign nevus. [1] It appears like a melanocytic nevus. [2] Histologically it is characterized by swollen, pale, polyhedral melanocytes, with pale cytoplasm and a central nucleus. [2] It is different to balloon cell melanoma, [3] which has larger nuclei and is structured like a melanoma. [1] It was first described by ...
