Etymed
seborrheic keratosis
Definition
A benign skin condition characterized by the excessive production and secretion of sebum, leading to the formation of waxy, scaly patches on the skin
Clinical context

The lesions are easily distinguished from malignant skin lesions by their 'stuck-on' appearance and greasy, keratotic surface. He has no history of significant sun exposure or skin cancer.
