Abstract
A 61-year-old male patient came to our emergency room because of abdominal pain. On admission, he complained of left-sided abdominal tenderness, and localized peritonitis was diagnosed. Blood examinations showed severe inflammation. Abdominal computed tomography revealed a thickened small intestinal wall and free air in the abdominal cavity. Under a diagnosis of peritonitis due to perforation of the small intestine, an emergency operation was performed. On laparotomy, the jejunal wall was thickened and perforated, necessitating a partial resection of the jejunum. The postoperative pathological and immunohistochemical diagnosis was enteropathy-type T-cell lymphoma. Chemotherapy and stem cell transplantation were conducted, and a complete response was obtained. He has been doing well for 16 months, to date, since the operation. There is no evidence of recurrence. We present this case with a review of the relevant Japanese literature.
