Dermoscopic Patterns of Acquired Reactive Perforating Collagenosis

Abstract

Acquired perforating dermatosis (APD) is a cutaneous disorder characterized by transepidermal elimination of dermal connective tissue. Acquired reactive perforating collagenosis (ARPC), the most common form of APD, is usually associated with underlying diabetes mellitus and chronic renal failure. Here we aimed to demonstrate dermoscopic patterns of ARPC in a series of 7 patients.
