A 39-year-old female with a changing skin lesion visited the Primary Care clinic. Due to its changing appearance, the lesion was biopsied and found to be a seborrheic keratosis. Seborrheic keratoses (SK) are benign epidermal tumors that become increasingly common as people age. The lesions tend to be elevated, with well-demarcated borders, and have a waxy or verrucous appearance. SKs are usually asymptomatic; however, they may become pruritic and occasionally bleed due to trauma caused by friction. SKs do not require treatment; however, they may be removed by cryosurgery or electrodesiccation if they become symptomatic or cosmetically bothersome.
