Lymphoid lesions of the parotid gland are much less common than their epithelial counterparts, and thus cytologic experience on fine‐needle aspiration (FNA) is limited. FNA of lymphoid lesions with ancillary aids (flow cytometry and immunophenotypic studies) can make a definitive diagnosis. All FNAs of the parotid gland performed at the Johns Hopkins Hospital in an 8‐yr span (1990–1998) were reviewed retrospectively. In all, 391 cases were done, of which 76 cases of lymphoid lesions were identified. The relevant cytology, histology, and flow cytometry were analyzed. Of the 76 lymphoid lesions, results included reactive lesions (n = 35), lymphoepithelial cysts (n = 27), malignant lymphomas (n = 12), an atypical lymphoid population (n = 1), and Sjogren's disease (n = 1). We conclude that both reactive and malignant lymphoid lesions of the parotid can be diagnosed on FNA with adjunctive tests such as flow cytometry and immunophenotyping, obviating the need for surgery.
