Fibroblastic reticular cell sarcoma of the small intestine:a very rare case report and clinicopathological diagnosis

A 54-year-old man was admitted for the evaluation of fever and abodominal pain. Radiological and endoscopic examination revealed a lung nodule and multiple small intestine uclers. Clinical diagnosis such as tuberculosis and Crohn's disease had been proposed. He developed intestine perforation after small bowel endoscopic procedure. During emergent surgery the involved intestinal segments were resected and a pathological diagnosis of fibroblastic histiocytic sarcoma(FBRC) was made. The patient died in the sixth month after the operation. The management of this cases highlighted the drawback of pattern recognition as the most commonly used clinical reasoning method, and the importance of histological investigation.
