| Abstract: | A case of signet-ring cell lymphoma initially diagnosed by fine needle aspiration (FNA) cytology is described. Immediate evaluation of air-dried smears showed a mixture of large and small lymphoid cells, including some signet-ring forms. Immunocytochemical studies of Cytospin preparations of the remaining aspirate yielded a diagnosis of a large-cell-type B-cell signet-ring lymphoma. Subsequent bone marrow biopsies confirmed the diagnosis of a low-grade lymphoma. The advantages of on-site evaluation in aspiration cytology are discussed. |
