Comedo-like Openings[edit]

Comedo-like openings are commonly seen in seborrheic keratosis and rarely in melanocytic nevi with a congenital pattern, such as papillomatous nevi and in melanoma [1]. They appear on dermoscopy as dark roundish structures, and clinically, can be appreciated as surface invaginations. Histopathologically, comedo-like openings correspond to the concave, keratin filled, invaginations of the epidermis [2].
