Cytologic diagnosis of reactive lymphadenopathy in fine needle aspiration biopsy specimens.
Reactive or benign lymphadenopathies were cytologically diagnosed in the aspirates of 62 (23.5%) of 265 cases with enlarged lymph nodes of the head, neck or inguinal region subjected to fine needle aspiration (FNA) biopsy. The cytomorphologic features characteristic of reactive lymphadenopathy are described in detail; some of the cell patterns were suggestive of a specific disease process. The similarities of cells and cell patterns that may pose differential diagnostic problems with malignant lymphomas are pointed out. This study emphasizes the role of FNA cytology in the diagnosis of some benign conditions.
