Acquired Reactive Perforating Collagenosis after Coronary Artery Bypass Graft Surgery / 대한피부과학회지

ABSTRACT

Perforating disorders are a group of skin disorders that present the characteristic clinical finding of transepidermal elimination. Acquired reactive perforating collagenosis is an uncommon condition characterized by umbilicated hyperkeratotic papules, and in almost all cases, it coexists with other disease conditions, such as diabetes mellitus, renal failure, and malignancies. The pathologic mechanism of this disease remains largely unknown. Here, we describe the case of a 42-year-old man who developed acquired reactive perforating collagenosis after coronary artery bypass graft surgery.
