[Multimodal therapy for peristomal pyoderma gangrenosum with topical cyclosporine].

Pyoderma gangrenosum (PG) is a rare neutrophilic disease. Clinically it shows a rapidly evolving painful ulceration with undermined violaceous wound edges. Peristomal PG is particularly resistant to treatment due to mechanical irritation. Two cases illustrate a multimodal therapeutic concept based on topical cyclosporine, hydrocolloid dressing and systemic glucocorticoids. In one patient re-epithelialization was attained after 7 weeks and the other patient experienced downsizing of the wound edges over 5 months.
