Seborrheic Keratoses

Seborrheic keratoses are a common noncancerous skin growth that typically appear in adulthood. These growths are characterized by their varied and often waxy, scaly, or brown-black appearance. Seborrheic keratoses can range in size from a few millimeters to several centimeters and are usually oval or round in shape. They can develop anywhere on the body but are most commonly found on the face, neck, chest, and back. The exact cause of seborrheic keratoses remains unclear, but they tend to run in families, suggesting a genetic component. Despite their sometimes alarming appearance, these growths are entirely benign and do not pose a threat to one's health. Treatment is typically sought for cosmetic reasons, irritation, or discomfort. Several options are available, including cryotherapy, curettage, or electrodessication, and in some cases, surgical shave removal. While these treatments can effectively remove the growths, seborrheic keratoses may reoccur or occur in other areas of the body over time.
