The technique of bronchoalveolar lavage (BAD permits the analysis of cells retrieved from the pulmonary parenchyma. While the clinical usefulness of the differential cellular analysis of BAL is controversial, utilization of newly available techniques may identify a specific etiology of the pulmonary disease. We report the case of a 50-year-old female in whom the diagnosis of recurrent non-Hodgkin's lymphoma post-bone marrow transplant was made using flow cytometry to phenotype the abnormal lymphocytes found in a BAL specimen. This case illustrates the clinical utility of immunopheno-typing abnormal or atypical lymphocytes by flow cytometry on BAL specimens, a technique that may be particularly useful in the posttransplant setting.
