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. Typically, seborrheic keratoses don’t become cancerous, but they can look like skin cancer. These skin growths are normally painless and require no treatment. You may decide, however, to have them removed if they become irritated by clothing or for cosmetic reasons.
