Seborrheic Keratoses

A seborrheic keratosis is a common non-cancerous skin growth. Everybody gets these lesions, and patients will get more of them with age. They are usually brown, black, light tan, or even gray. They often look waxy, scaly, and slightly raised. They usually appear on the head, neck, chest, or back but can occur anywhere on the skin except the palms and soles.

Seborrheic keratosis are harmless and not contagious. They do not need to be treated. You may decide to have them removed if you do not like the way they look, but this is not covered by insurance.

Seborrheic keratosis can be removed by spraying them with liquid nitrogen or by a simple surgical procedure in which the skin is numbed and the lesion is scraped off with a surgical blade.
