title: Dehydrated Human Amnion/Chorion Membrane as Adjunctive Therapy in the Multidisciplinary Treatment of Pyoderma Gangrenosum: A Case Report.
abstract: Pyoderma gangrenosum (PG) is an uncommon chronic and progressive skin disorder that can lead to severe tissue necrosis, pathergy, horrendous pain, and disfigurement if not properly and promptly diagnosed and treated. Systemic treatment traditionally consists of long-term immunosuppression. Topical care of the painful wound often represents a clinical challenge. A 77-year-old woman with multiple comorbidities including venous insufficiency and diabetes mellitus was diagnosed through exclusion with refractory, painful PG. She was managed for 3 months by a multidisciplinary team comprised of an internist, 2 dermatologists, and a podiatric wound care specialist using immunosuppressive therapy, several local wound care modalities, and supportive bandages. During that time, severe wound pain continued unabated and the affected area changed from 3 separate wounds measuring 1.4 cm x 1.0 cm x .01 cm, 1.2 cm x 0.5 cm x 0.1 cm, and 0.6 cm x 0.5 cm x 0.1 cm to 1 wound measuring 8.0 cm x 10.3 cm x 0.1 cm. At that time, dehydrated human amnion/chorion membrane (dHACM) allograft, previously reported to facilitate healing venous leg and diabetic foot ulcers, was incorporated into the treatment plan. The patient reported wound pain decreased from 10 out of 10 to 5 out of 10 within hours following application. At the 4 day follow-up visit, she reported no pain; after 1 week, the wound decreased 6.4 cm x 9.4 cm x 0.1 cm in size and after 2 months (3 applications) the wound had reduced in area from 103 cm2 to 57.96 cm2 (reduced by more than half [56%]). In this patient, following the application of dHACM as an adjunct to immunosuppressive therapy, pain receded and wound healing commenced. Additional controlled studies are needed to ascertain the generalizability of this observation.
