Lymphomatous peritoneal effusion

View larger version (115K): [in this window] [in a new window]   Figure 1. A Wright stained smear of ascitic fluid obtained from a patient who presented with signs and symptoms of peritonitis is shown. There is a marked leukocytosis consisting primarily of neutrophils. In addition large cells with basophilic cytoplasm, round to irregular nuclei and prominent nucleoli are also present (arrow).

The heterogeneity in size and nuclear contour of the atypical cellular infiltrate is more evident. On flow cytometric analysis these cells marked as CD19, CD20 positive with kappa light chain restriction consistent with lymphomatous involvement of the peritoneum.

View larger version (108K): [in this window] [in a new window]   Figure 3. The neoplastic features of these cells are most evident in this image. The cells have extensive agranular basophilic cytoplasm, variability in nuclear contours and one or more prominent nucleoli. A mitotic figure is also noted. A subsequent gastric biopsy confirmed the diagnosis of diffuse large B-cell lymphoma (DLBCL) in this patient.
