Nevoid melanoma
Nevoid Melanoma
Nevoid melanoma (pronunciation: nee-void mel-uh-noh-muh) is a rare form of melanoma, a type of skin cancer that originates from the pigment-producing cells known as melanocytes.
Etymology
The term "nevoid" is derived from the Latin word "naevus", which means birthmark or mole, and "melanoma" comes from the Greek words "melas" (black) and "-oma" (tumor). Thus, "nevoid melanoma" refers to a melanoma that resembles a mole.
Definition
Nevoid melanoma is a variant of melanoma that is often mistaken for a benign mole due to its similar appearance. It is characterized by its small size, symmetrical shape, and uniform color. Despite its benign appearance, nevoid melanoma is a malignant tumor and can be aggressive if not diagnosed and treated early.

Diagnosis
Diagnosis of nevoid melanoma can be challenging due to its resemblance to a benign mole. It often requires a biopsy, where a small sample of the suspicious skin lesion is removed and examined under a microscope.
Treatment
Treatment for nevoid melanoma typically involves surgical removal of the tumor. Additional treatments such as chemotherapy, radiation therapy, or immunotherapy may be recommended depending on the stage of the disease.
