“…In this case, it was difficult to suspect malignant lymphoma from our initial medical examination and CT findings. Because the patient had a history of two malignant tumors, we first suspected metastatic recurrence of the gingival or lung cancers, which has been reported previously (7,8). Although there was no dilatation of the intestine proximal to the primary lesion, the possibility of primary small intestinal cancer or a carcinoid could not be ruled out.…”

A 74-year-old man presented with abdominal swelling. Computed tomography revealed massive ascites and localized thickening of the small intestinal wall. Enteroscopy showed ulcerative lesions along the circumference of the jejunum. Histological examination showed dense proliferation of large lymphoid atypical cells, and immunohistochemistry showed CD20 and CD10 positivity, CD3 negativity, and Ki67 labeling index >80%. Cytology of the ascitic fluid revealed large lymphoid cells. These findings suggest that small intestine primary diffuse large B-cell lymphoma (DLBCL) caused the ascites. Massive ascites as an initial symptom of primary DLBCL of the jejunum is rare. Herein, we describe this unusual presentation.
