Becker's Nevus

Becker's Nevus (pronounced: BEK-erz NEH-vus), also known as Becker's Pigmented Hairy Epidermal Nevus, is a skin disorder predominantly affecting males. The condition is named after the dermatologist who first described it, Samuel William Becker.

Etymology

The term "nevus" is derived from the Latin word "naevus", which means "birthmark". The condition is named after Samuel William Becker, an American dermatologist who first described the condition in 1949.

Definition

Becker's Nevus is a type of epidermal nevus, which is a benign overgrowth of the epidermal layer of the skin. It is characterized by an irregularly shaped, hyperpigmented patch that may be covered with excessive hair (hypertrichosis). The nevus usually appears first during puberty.

Symptoms

The primary symptom of Becker's Nevus is the appearance of a large, irregularly shaped, darkly pigmented patch of skin. This patch is often covered with excessive hair. The nevus may also be associated with minimal acanthosis and hyperkeratosis. It most commonly appears on the upper body, particularly the chest, shoulder, and upper arm.

Causes

The exact cause of Becker's Nevus is unknown. However, it is believed to be due to an overproduction of melanocytes, the cells that produce melanin, the pigment that gives skin its color. Some studies suggest a possible hormonal influence, as the nevus often first appears during puberty.

Treatment

There is no cure for Becker's Nevus. Treatment is usually aimed at improving the cosmetic appearance of the nevus. This may include laser therapy to lighten the pigmentation and reduce hair growth.
