&NA;Extramedullary plasmacytoma (EMP) of the small bowel is a rare entity previously reported as a cause of intestinal obstruction or bleeding. A case report of this disease entity presenting as an ileocolic fistula is reported. EMP is diagnosed by the following critiera: 1) absence of paraproteinemia; 2) absence of Bence Jones proteinuiria; 3) normal skeletal survey; and 4) normal bone marrow biopsy specimen. Gastrointestinal plasmacytoma often occurs as a manifestation of multiple myeloma. EMP of the gastrointestinal tract is a rare cases manifestation of the disease, accounting for 13 per cent of all cases of EMP. It is a slow‐spreading, radiosensitive tumor with a high tendency toward local recurrence. Surgical excision combined with radiotherapy is the treatment of choice for EMP of the gastrointestinal tract.
