【 摘 要 】

A 60-year-old man complained of nausea, vomiting, decreased appetite, and a feeling of abdominal fullness in August 2013. Based on biopsy findings from an upper gastrointestinal endoscopy examination, a diagnosis of non-Hodgkin’s lymphoma (NHL), diffuse large B-cell lymphoma (DLBCL), non-GC type, was made. F18-fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) revealed abnormal accumulations solely in the gastric wall (SUVmax = 14.5), the left adrenal gland (SUVmax = 14.3), and the right adrenal gland (SUVmax = 8.5). The clinical stage (Ann Arbor) was IVA, the serum LDH level was within the reference range, and the International Prognostic Index (IPI) was low-intermediate. The serum soluble IL-2 receptor level was within the reference range, and there was no evidence of HIV, EB virus, or autoimmune disease. After the completion of 4 cycles of R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) and 2 parallel cycles of prophylactic intrathecal (I.T.), an upper gastrointestinal endoscopy and a FDG-PET/CT examination showed complete remission (CR). The patient received 8 cycles of ritsuximab therapy, 6 cycles of CHOP, and 3 cycles of I.T. The patient has maintained a CR for about 14 months. A literature search revealed that malignant lymphoma with involvement confined to the adrenal gland and gastrointestinal tract is exceedingly rare, and only 3 cases of malignant lymphoma have been reported, with involvement of the stomach in 2 cases and the duodenum in 1 case. All of the cases were diagnosed as DLBCL. The case described herein represents the third case with involvement of the stomach.
