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, but may rarely occur in the mouth, intestines, or eye (uveal melanoma). [1] [2] In women, melanomas most commonly occur on the legs; while in men, on the back. [2]
The histopathologic characteristics of melanoma in FAMMM kindreds are not different from those seen in sporadic cases of melanoma and, thus, are not useful in diagnosing the syndrome. Superficial spreading melanoma (SSM) and nodular melanoma are the most frequently encountered histological melanoma subtypes in patients with CDKN2A mutations ...
Most melanoma consist of various colours from shades of brown to black. A small number of melanoma are pink, red or fleshy in colour; these are called amelanotic melanoma and tend to be more aggressive. Warning signs of malignant melanoma include change in the size, shape, color or elevation of a mole.
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 ...
Dysplastic nevus syndrome (B-K mole syndrome, familial atypical multiple mole–melanoma syndrome, familial melanoma syndrome) Ephelis (freckle) Epithelioid blue nevus; Generalized lentiginosis; Giant pigmented nevus (bathing trunk nevus, congenital nevomelanocytic nevus, garment nevus, giant hairy nevus, nevus pigmentosus et pilosus)
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.
Amelanotic melanoma is a type of skin cancer in which the cells do not make any melanin. [1]: 696 [2] They can be pink, red, purple or of normal skin color, and are therefore difficult to diagnose correctly. They can occur anywhere on the body, just as a typical melanoma can.
Removal can also occur by shaving. Shaving leaves a red mark on the site but changes to the patient's usual skin color in about 2 weeks. However, there might still be a risk of spread of the melanoma, so the methods of melanoma diagnosis, including excisional biopsy, are still recommended even in these instances. Moles can also be removed by ...
