ABSTRACT
The acinic cell carcinoma (ACC) is very rare in the nasal cavity. A 57-year-old woman suffered from nasal obstruction, postnasal dripping, and hyposmia for 2 months. Rhinoscopic examination revealed a huge polypoid mass in the right inferior and anterior nasal fossa of the nasal cavity and the mass was resected. The tumor showed the classic acinar and trabecular features of ACC on light microscopic examination. The finely granular cytoplasmic granules stained with periodic acid-schiff (PAS) and diastase digested-PAS, but not with alcian blue at pH 2.5 and mucicarmine. On ultrastructural examination, tumor cells contained numerous secretory granules diagnostic of ACC.
Key Words: Acinic cell carcinoma; Nasal cavity
