[Bowel Perforation in a Patient with Adult T-Cell Leukemia/Lymphoma].

Le résumé fourni par la source

Adult T-cell leukemia/lymphoma(ATLL)can infiltrate throughout various organs and frequently involves the gastrointestinal tract. However, bowel perforation in ATLL patients is rare. Herein, we present a case of ATLL with bowel perforation. A 75-year-old man presented with bowel distension. Computed tomography showed a large mass of the cecum. Edema and stenosis of the ascending colon was seen on colonoscopy, and tumor on the anal side of the stenosis was also found. After admission, the patient complained of abdominal pain with a peritoneal irritation sign. Free air was seen around a large mass of the cecum on computed tomography and an emergency operation was performed under the diagnosis of bowel perforation. Microscopic examination revealed bowel infiltration of ATLL. Gastrointestinal perforation can be caused by ATLL itself and is associated with a poor prognosis. The standard treatment for ATLL is chemotherapy but emergency surgery is necessary in case of perforation. It is important to observe the patient with ATLL carefully.
