A Case of Acquired Reactive Perforating Collagenosis Triggered by an Insect Bite / 대한피부과학회지

ABSTRACT

Reactive perforating collagenosis (RPC) is one of a range of essential perforating disorders. Two types have been recognized the childhood or inherited form, and the adult or acquired form. Acquired RPC is usually associated with systemic diseases, especially diabetes mellitus, and/or renal failure. We present a case of a 47-year-old female with umbilicated skin lesions triggered by an insect bite. Histology from the lesion revealed transepidermal elimination of collagen.
