We report a case of Burkitt's lymphoma infiltrating into pleural and peritoneal effusion.
A 20-year-old man admitted to Showa University Fujigaoka Hospital in July 1998 reported abdominal colic. Ultrasonography and computed tomography (CT) were used to image the thickness of the small intestine and pleural and peritoneal effusion. Cytological examination of pleural effusion and ascites showed many neoplastic lymphoid cells with a high N/C ratio. Cytoplasms were basophilic and had small vacuoles stained by oil red 0. A chromosome spread showed the characteristic translocation of t (8; 14)(q24; q32). Based on these cytological findings, we diagnosed this case as Burkitt's lymphoma.
