Calcifying Fibrous Tumor: Report of an Exceptional Lesion Localized to the Jejunum

Background: Calcifying fibrous tumor (CFT) is a rare benign mesenchymal tumor; with a predilection for children and young adults that usually arises in the subcutaneous and deep soft tissues, pleura, or peritoneum. CFT of the gastrointestinal tract is exceedingly rare. Discussion: We describe here a patient with an unusual presentation-intestinal calcifying fibrous tumor. This 26-year-old man came to our emergency department with abdominal distension and intermittent epigastric cramping pain. The physical examination was negative. Colonoscopy showed an intestinal polyp, measuring 3 cm in greatest axe. The macroscopic examination showed a segmental resection of jejunum with pedunculated polyp. The polyp had a smooth, shiny and gray surface, it measured 3 cm. Histologically, it was consisting of hyalinized, hypocellular lamellar collagen, bland spindle cells, chronic inflammatory cell infiltrates, and psammomatous or dystrophic calcifications. Conclusion: CFT of the gastrointestinal tract is exceedingly rare. We describe a case arising in the small intestine, and discuss the differential diagnosis with other common and uncommon spindle cell lesions.
