AbstractA 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.
