Which dermatologic term refers to a linear crack or break extending from the epidermis into the dermis?

Explanation:
A fissure is a linear crack or break that extends from the epidermis into the dermis. This makes it distinct from an ulcer, which is tissue loss with a crater-like edge; from scales, which are flakes of dried skin on the surface; and from scars, which are fibrous tissue that forms after healing. Fissures are often painful because the crack reaches into the deeper skin layers.
