Calcifying fibrous tumor of the small intestine.

We report an observation of a calcifying fibrous tumor discovered through imaging in a 28-year-old male presenting with chronic abdominal pain associated with diarrhea. The abdominal computed tomography scan revealed an intraperitoneal mass located in the right iliac fossa, containing calcifications and measuring 37 × 49 mm; biopsies were non-contributory. A diagnosis of a suspected gastrointestinal stromal tumor was made, and an ileocecal resection was performed. Histological examination confirmed the diagnosis of a calcifying fibrous tumor. The patient was doing well without recurrence six months post-surgery. Only a few observations of calcifying fibrous tumors have been reported in the literature. These benign tumors are often discovered incidentally and have fairly characteristic clinical and pathological features that allow them to be distinguished from stromal tumors.
