A mole can be either subdermal (under the skin) or a pigmented growth on the skin, formed mostly of a type of cell known as a melanocyte. The high concentration of the body's pigmenting agent, melanin, is responsible for their dark color. Moles are a member of the family of skin lesions known as nevi (singular "nevus"), occurring commonly in ...

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 management of nevi depends on the type of nevus and the degree of diagnostic uncertainty. Some nevi are known to be benign, and may simply be monitored over time. Others may warrant more thorough examination and biopsy for histopathological examination (looking at a sample of skin under a microscope to detect unique cellular features). For ...
Skin tags are benign growths that appear frequently on the neck, eyelids, groin, or armpits. Unlike a mole, which is pigmented, or a wart, which is round and rough to the touch, a skin tag looks ...
A blue nevus is a type of coloured mole, typically a single well-defined blue-black bump. [1] [2] The blue colour is caused by the pigment being deep in the skin. [4] Diagnosis is by visualisation and dermoscopy. [4] A biopsy is sometimes performed, or the whole lesion surgically removed. [3]
Melanoma, the deadliest form of skin cancer, can grow quickly and spread to any organ if not found and treated early, the Cleveland Clinic warns.More than 100,000 new cases of melanoma will be ...
Angiofibroma (AGF) is a descriptive term for a wide range of benign skin or mucous membrane (i.e. the outer membrane lining body cavities such as the mouth and nose) lesions in which individuals have: benign papules, i.e. pinhead-sized elevations that lack visible evidence of containing fluid;
