What is Seborrheic Keratosis?

Seborrheic keratosis is one of the most common types of noncancerous (benign) skin growths in older adults. In fact, most people develop at least one seborrheic keratosis at some point in their lives.

A seborrheic keratosis usually appears as a brown, black or pale growth on the face, chest, shoulders or back. The growth has a waxy, scaly, slightly elevated appearance. Occasionally, it appears singly, but multiple growths are more common. Though not painful, seborrheic keratoses may prove bothersome depending on their size and location. Be careful not to rub, scratch or pick them. This can lead to inflammation, bleeding and infection. Typically, seborrheic keratoses don't become cancerous, but they can look like skin cancer.

Treatment of seborrheic keratoses usually isn't necessary. However, you may want them removed if they become irritated, if they bleed because your clothing rubs against them, or if you simply don't like how they look or feel.

This type of growth is never deeply rooted, so removal is usually simple and not likely to leave scars. Your doctor can remove seborrheic keratoses using several methods, including: cryosurgery, curettage, and electrocautery.
