title: [Adult dermatomyositis with angiopathy and cecum perforation].
abstract: This previously healthy 43-year-old man was admitted to our hospital with a history of rash, dysphagia and severe myalgia for two months. Physical examination showed prominent edema and erythema over the face and the chest, scattered ulcerations on the trunk, and muscle atrophy most prominent proximally. Serum levels of muscle enzymes were remarkably increased. Two weeks of oral prednisolone therapy (40 mg/day) was not effective, and betamethasone intravenous pulse therapy (3 x 1000 mg) was followed by slight clinical improvement. However, 12 days after pulse therapy, he complained abdominal pain on the right lower quadrant. The surgical findings included peritonitis due to single perforation of the cecum. After operation, cyclosporine therapy was added and over the next 14 month a considerable clinical improvement was noted. Prednisolone was reduced from 80 mg to 10 mg daily. Biopsy specimens from ulcerated+ skin and perforated cecum showed prominent vascular abnormalities: arterial and venous intimal hyperplasia, occlusion of vessels by fibrin thrombi, and lymphocytic infiltration which affected veins of all sizes. The evidence strongly suggests that both skin ulcers and cecum perforation were caused by vasculitis and occlusion of vessels, which often seen in childhood dermatomyositis.
