Seborrheic keratosis

Seborrheic Keratosis (pronunciation: seb-o-REE-ik ker-uh-TOE-sis) is a common, benign skin growth that appears in middle-aged and older adults.

Etymology

The term "Seborrheic" is derived from the word "Seborrhea" which means "flow of oil", referring to the often oily surface of these growths. "Keratosis" comes from the Greek word "Keratos" meaning horn, referring to the hardened, warty nature of the growth.

Description

Seborrheic keratosis often appears as a brown, black or light tan growth on the face, chest, shoulders or back. The growth has a waxy, scaly, slightly elevated appearance. Despite their appearance, these growths are not related to skin cancer and pose no health risk. They can be a cosmetic concern to some people.

Causes

The exact cause of seborrheic keratosis is unknown. It tends to run in families, suggesting a genetic link. Sunlight also seems to play a role, as the growths most often appear on sun-exposed areas.

Treatment

Seborrheic keratosis does not require treatment unless it becomes irritated or the individual wishes to remove it for cosmetic reasons. Treatment options include cryotherapy, electrosurgery, and curettage.
