Isolated corymbose collagenoma responding to intralesional triamcinolone acetonide and hyaluronidase injections.

Collagenomas are connective tissue nevi with circumscribed hamartomatous proliferation of collagen. Due to their benign nature and lack of any simple medical treatment, they are most often left untreated. We present a case of isolated corymbose collagenoma, a distinct morphological variant not described hitherto that was successfully treated with intralesional injections of combination of triamcinolone acetonide and hyaluronidase.
