Melanocytic Nevus

Melanocytic nevus (pronunciation: /mɛˈlænəˌsaɪtɪk ˈniːvəs/), also known as a mole, is a type of lesion that contains nevus cells. The term is derived from the Greek words 'melas' meaning black and 'kytos' meaning cell, and the Latin word 'nevus' meaning birthmark.

Definition

A melanocytic nevus is a small, dark spot on the skin that is usually brown or black. It is formed by clusters of pigmented cells known as melanocytes. These cells are responsible for producing melanin, the pigment that gives color to the skin, hair, and eyes.

Types

There are several types of melanocytic nevi, including:

Diagnosis

Diagnosis of a melanocytic nevus is typically made through a physical examination and a review of the patient's medical history. In some cases, a biopsy may be performed to rule out melanoma.

Treatment

Treatment for a melanocytic nevus is usually not necessary unless it changes in size, shape, or color, or if it becomes painful or itchy. In these cases, the nevus may be removed surgically.
