A Case of Generalized Pyoderma Gangrenosum Involving Scalp and Face

Purpose: Pyoderma gangrenosum is a rare inflammatory, reactive dermatosis marked by painful cutaneous ulcer. The causes of pyoderma gangrenosum remain unclear. Gastrointestinal, hematological, rheumatological, and immmune disorders may be associated with pyoderma gangrenosum. The appearance of this disease may range from mild skin ulcers to life-threatening conditions. Generalized multiple ulcerative pyoderma gangrenosum is very rare. Here we report our experience with a case of multiple ulcerative pyoderma gangrenosum accompanied by ulcerative colitis. Methods: A 67-year-old man had cutaneous ulcers at multiple sites including the scalp, face, chest, abdomen, hands, and buttocks. He also developed gastrointestinal symptoms such as intermittent dyspepsia and bloody excrement. Debridement and irritation aggravated the disease progress. We gave a diagnosis of pyoderma gangrenosum with ulcerative colitis based on the clinical appearance and biopsy. The patient was treated with systemic intravenous steroid therapies and careful wound cares. Ulcers of the scalp and buttocks were treated with split thickness skin grafts. Results: Most of the multiple cutaneous ulcers were treated by systemic intravenous steroid therapies and wound cares. The rest of the ulcers were treated with skin grafts. Systemic intravenous steroid therapy was used to treat the ulcerative colitis. Conclusion: Generalized multiple ulcerative pyoderma gangrenosum is very rare. Without making an accurate diagnosis, hasty surgical treatments could aggravate the progression of the disease. Additionally, care should be taken to systemically treat underlying disease as well as administrating local treatments for the skin lesions. Intravenous systemic steroid therapy and skin grafts are useful treatments for generalized pyoderma gangrenosum.
