Seborrheic Keratosis Color and Structure

The color of lesions is extremely variable, including white, pink, brown and black, and the color may vary within a single lesion. Lesions tend to be sharply demarcated, oval, and often oriented along skin cleavage lines. Most have a stuck-on appearance and waxy texture. The surface tends to crumble when picked. Raised or pedunculated seborrheic keratoses may be indistinguishable from skin tags and compound melanocytic nevi.
