Ulcers caused by bullous morphea treated with tissue-engineered skin

Bullous morphea is an uncommon form of localized scleroderma. The exact pathogenesis is unknown and treatment of the accompanying ulcers is problematic. We report a patient with bullous morphea with long-standing ulcers whom we successfully treated with the tissue-engineered skin Apligraf (Organogenesis Inc., Canton, MA). The patient experienced rapid improvement in granulation tissue and the ulcers healed 4 months after a single application. The rationale for the use of Apligraf is based on experience with patients with venous ulcers who have surrounding peri-ulcer fibrosis. This condition, termed lipodermatosclerosis, has been reported as a poor prognostic factor for healing, yet many ulcers associated with lipodermatosclerosis may respond to treatment with tissue-engineered skin. Taken in concert, these results suggest a role for tissue- engineered skin in the treatment of chronic wounds with surrounding fibrosis.
