Abstract
A 57-year-old woman with ovarian cancer underwent sigmoid colostomy because of rectovaginal fistula 4 years after primary surgery. Four days postoperatively, the discharge from the midline incision increased. Skin redness around the stoma and ulceration was found which lead to the diagnosis of pyoderma gangrenosum (PG). The necrosis spread widely around the wound, but the epithelization was finally restored by corticosteroid ointments on postoperative day 44. The characteristic ulcers were detected at the site of the central venous port on the left upper arm and the site of the peripheral intravenous feeding, and were both diagnosed as PG. PG is a rare disease which presents a characteristic ulcer as a cardinal symptom, and is often combined with inflammatory bowel diseases, autoimmune diseases and malignant tumors. It sometimes occurs around the stoma, but there have been no reports about consecutive PG occurrence at other sites such as the venous port and the peripheral intravenous puncture. We report this rare case with a review of the literature.
