What is Seborrheic Keratosis?

Signs and Symptoms

Seborrheic Keratoses are described as greasy or waxy wart-like lesions with a “stuck-on” appearance. They can range in color from skin tone to tan, brown, gray or black. These benign keratosis also vary widely in size and shape and tend to enlarge over time. Occasionally these spots can become itchy or irritated especially if they become snagged or rubbed by clothing or jewelry. Since these lesions are superficially adherent to the skin, sometimes parts of a keratosis will become scraped off. Age spots can vary in extent from a few scattered lesions to many lesions with widespread distribution across the entire body. Certain types of skin cancer and other cutaneous lesions can look similar to Seborrheic Keratoses which is why it is important to be evaluated by a trained dermatologist.
