Primary effusion lymphoma with B-cell phenotype.
We describe here a case of primary effusion lymphoma that occurred in a 78-year-old woman. She was successively treated with prednisolone but died 15 months after the diagnosis of primary effusion lymphoma. The immunohistochemistry revealed the neoplastic cells to be CD19(+), CD20(+), CD21(+), Sm-Ig(+), and HLA-DR(+). This patient exhibited clonal IgH and clonal kappa light chain gene rearrangement, indicating a B-cell origin. The present case was distinguished from the majority cases of HHV-8-positive primary effusion lymphoma. Here we present clinical details of response to therapy in this case.
