Seborrheic Keratoses

What is Seborrheic Keratoses

Seborrheic keratoses are raised growths on the skin. Seborrheic means greasy and keratosis means thickening of the skin. These lesions are benign overgrowths of epithelium, largely appearing on the torso, face, and neck. Seborrheic keratoses have a variety of clinical appearances, and they develop from the proliferation of epidermal cells. They are seen on almost everyone over the age of 50. The borders are typically irregular, and they range in color from beige or gray-white to very dark brown. The exact cause of seborrheic keratoses is unknown; however, they seem to run in families.

Seborrheic keratoses are not contagious and do not spread.These "barnacles" of older skin can number only a few to as many as hundreds. Although often raised and dry, they can be flatter and greasier (seborrheic) in texture. Treatment - Creams, ointments, or other medication can neither cure nor prevent seborrheic keratoses. Most often seborrheic keratoses are removed by cryosurgery, curettage, or electrosurgery.
