[A Case of T-Cell Lymphoma Treated by Emergency Surgery Due to Bleeding of Jejunal Lesion].

A 78-year-old man was aware of lightheadedness and darkness at a routine outpatient visit, and his blood pressure was declined at 87/51 mmHg. Contrast-enhanced CT scan showed an extravascular leakage image at jejunum. We diagnosed as small intestinal hemorrhage. Because he was in hemorrhagic shock, emergency surgery was performed. A tumor was found coincident with the bleeding site, and partial resection of the small intestine including enlarged lymph nodes was performed. Based on the pathological findings of T-cell origin and positive for serum anti-HTLV-1 antibody, he was suspected as adult T-cell leukemia/lymphoma(ATLL). Endoscopic examination of the upper and lower gastrointestinal tracts, bone marrow examination, and PET-CT scan were performed, but no other lesions were found. We report a case of the T-cell lymphoma with suspected solitary ATLL of the jejunum.
