Abstract

Reactive perforating collagenosis is commonly recognised as an unusual form of transepithelial elimination of collagen and elastin fibres which are extruded through the epidermis in patients with a genetic predisposition or underlying diseases, such as diabetes mellitus or renal diseases. We present the unusual case of an 87-year-old diabetic male with a giant form of reactive perforating collagenosis and review the available literature.

Keywords: dermatology; diabetes; drugs and medicines; endocrinology; geriatric medicine; other geriatric medicine.
