A Case of Reactive Perforating Collagenosis Associated With Diabetes Mellitus / 대한피부과학회지

ABSTRACT

Reactive perforating collagenosis(RPC) is a kind of perforating dermatosis characterized by transepithelial elimination of an altered dermal collagen. RPC is classified into two forms; childhood or inherited form, and adult or acquired form. Acquired RPC is reported to occur in association with the severe complicated diabetes mellitus, chronic renal failure and other diseases. We describe a patient with acquired RPC associated with controlled, non-complicated diabetes mellitus and severe pruritus. Skin lesions showed rapid improvement after the intralesional injection of triamcinolone.
