Multiple peritoneal calcifying fibrous tumors revealed by ischemic colitis.

ABSTRACT

We report the case of a 41-year-old man presenting with multiple calcifying fibrous tumor (CFT) revealed by ischemic colitis. Peritoneal nodular lesions involved omental, mesenteric, mesorectal, and mesocolic serosal surfaces. Histologically, nodules were composed of dense bundles of collagen, calcifications, and lymphoplasmacytic infiltrate. These findings were diagnostic of CFTs, a rare and often asymptomatic benign fibrous process. Multiple peritoneal CFTs are very uncommon and usually occur in women. Calcifying fibrous tumors are usually cured by surgical excision. The differential diagnosis and histogenesis of this entity are discussed.
