Reactive perforating collagenosis (RPC) is a rare form of dermatosis. It forms with perforating folliculitis, Kyrle's disease, and serpiginous perforating elastosis, which is a group of perforating dermatosis. RPC can be hereditary with autosomal dominant transmission or it can be acquired, which is usually observed in diabetics with chronic renal failure. Here we report a new observation in a 72-year-old woman treated by phototherapy with a favorable outcome.
Keywords: acquired perforating collagenosis; familial reactive perforating collagenosis; perforating dermatosis.
