An acral nevus is a cutaneous condition of the palms, soles, fingers, or toes (peripheral body parts), characterized by a skin lesion that is usually macular or only slightly elevated, and may display a uniform brown or dark brown color, often with linear striations. [1]: 1726. Acral nevi may occur in all ethnic groups, but are more common in ...
Melanocytic nevus. A melanocytic nevus (also known as nevocytic nevus, nevus-cell nevus and commonly as a mole) [1][2] is usually a noncancerous condition of pigment-producing skin cells. It is a type of melanocytic tumor that contains nevus cells. [2] A mole can be either subdermal (under the skin) or a pigmented growth on the skin, formed ...
Acral lentiginous melanoma. Acral lentiginous melanoma is a type of skin cancer. [6] It typically begins as a uniform brownish mark before becoming darker and wider with a blurred irregular edge, most frequently seen in the foot of a person with darker skin. [6] It may become bumpy and ulcerate. [6]
Junctional, intradermal, and compound. A benign melanocytic nevus is a cutaneous condition characterised by well-circumscribed, pigmented, round or ovoid lesions, generally measuring from 2 to 6 mm in diameter. [1] A benign melanocytic nevus may feature hair or pigmentation as well.
So, 13 years ago, when an unusual spot appeared on my wrist, I was quick to point it out to my dermatologist, who promptly told me he was unconcerned. The answer was the same when I asked about it ...
Lentigo. A lentigo (/ lɛnˈtaɪɡoʊ /) (plural lentigines, / lɛnˈtɪdʒɪniːz /) is a small pigmented spot on the skin with a clearly defined edge, surrounded by normal-appearing skin. It is a harmless (benign) hyperplasia of melanocytes which is linear in its spread. This means the hyperplasia of melanocytes is restricted to the cell ...
Some melanocytic nevi, and melanoma-in-situ (lentigo maligna) have resolved with an experimental treatment, imiquimod (Aldara) topical cream, an immune enhancing agent. In view of the very poor cure rate with standard excision, some surgeons combine the two methods: surgical excision of the lesion, then three months treatment of the area with ...
Melanocytic tumors of uncertain malignant potential (MELTUMP) are melanocytic lesions in the dermis that cannot be classified by morphology as either benign naevi (moles) or malignant melanomas because the mass shows features of both. Several lesion types may be classified as MELTUMPs: these include atypical melanocytic proliferations with ...
