title: Cytologic detection of malignant lymphoma cells in urine and hydrocele fluid.
abstract: The cytologic finding of malignant lymphoma cells in the urine and hydrocele fluid of a 32-year-old man is reported. The tumor cells were scattered singly and were slightly larger than normal lymphocytes. Their nuclei were ovoid or irregular in shape. Hyperchromasia, coarsely distributed chromatin and prominent nucleoli were characteristic. Histologic examination showed a non-Hodgkin's malignant lymphoma, corresponding to the large-cell type of diffuse lymphoma.
