A 75-year-old woman who had persistent right abdominal pain for 16 months visited our department for the detailed examination. Plain abdominal X-ray film showed linear calcification along the colonic wall from the ascending to the descending colon. Abdominal CT scan showed marked colonic wall thickening with calcification of the ascending and transverse colon. Colonoscopic view showed blue-purple colored mucosa with indistinct vascular pattern from the cecum to the descending colon and several erosions in the transverse colon. Histological examination of the biopsied specimen showed hyaline like degeneration aroud the small blood vesels and fibrous thickening in the submucosa. Based on these findings, the patient diagnosed ischemic intestinal lesion caused by phlebosclerosis. This disease has rarely been reported and their pathogenesis remain unknown. We discuss the clinical and histological characteristics of this disease.
