Fine-needle aspiration of lymph nodes: use of flow cytometry immunophenotyping.

Abstract

Fine-needle aspiration of lymph nodes can be used successfully in the clinical work-up of lymphadenopathy. The procedure has some limitations, some of which can be overcome by using such ancillary studies as flow cytometry or immunophenotyping. The authors discuss the use of these techniques in establishing definitive diagnosis of the most common and well-recognized lymphadenopathies.
