These are common in elderly people, especially in the periorbital areas. Most patients have had high exposure to UV radiation, and the solar damage to the supporting dermis allows the pilosebaceous duct to become more easily distended with impacted corneocytes. The edge of the adjacent skin may be mistaken for the pearly edge of a basal cell carcinoma. The lesions are easily removed with a comedo expressor, but they slowly recur.
