ABSTRACT
The authors present the fine needle aspiration cytology (FNAC) cytologic findings of a case of extranodal marginal zone B cell lymphoma (MZBCL), which featured abundant plasma cells and eosinophilic histiocytes arising in both parotid glands. A 49-year-old female presented with palpable masses in both parotid glands. She had been suffering from systemic lupus erythematosus and rheumatoid arthritis. The lesions were evaluated by FNAC and smears showed a small number of clusters of oncocytic cells with abundant eosinophilic granular cytoplasm and small nuclei, intermixed with small to medium-sized lymphoid cells containing round to lobulated nuclei, which suggested Warthin's tumor. Some of lymphoid cells had a plasmacytoid appearance, and some scattered large cells contained a large amount of eosinophilic cytoplasm. Bilateral superficial parotidectomy was performed and a histopathologic study indicated MZBCL with abundant plasma cells, intermixed with eosinophilic histiocytes. The presence of oncocytic cells and a mixture of lymphoid and plasma cells indicates Warthin's tumor, but the cytologic features of a relatively monotonous small to medium-sized lymphoid infiltrate suggest the possibility of MZBCL in the clinical setting of an FNAC study performed on a patient suffering from a connective tissue disease.
