Pyoderma gangrenosum (PG) is a rare neutrophilic inflammatory condition. It is characterised by painful, rapidly expanding, violaceous, undermined ulcers. Immunosuppressants are key to management, but large chronic ulcers often result.

University Hospital Birmingham, UK, evaluated MPPT in three patients with chronic inactive stable PG ulcers. The patients were treated with MPPT for five consecutive days. All demonstrated new granulation tissue consistent with improved healing. See the poster presented at the British Dermatology Association meeting in Edinburgh, July 2-5, 2018.
