Acinic cell carcinoma of the parotid gland: A diagnostic dilemma on cytology

Malays J Pathol. 2019 Aug;41(2):191-194.

Abstract

Introduction: Acinic cell carcinoma (ACC) represents 1-6% of parotid gland neoplasms.

Case report: We report cytomorphological features of two uncommon variants of acinic cell carcinoma. The first case was an eleven-year-old female with a nodular mass in parotid and the FNA smears demonstrated a lymphoepithelial lesion composed of epithelial tumour cells with features of acinar cells in a lymphoid background. The second case was a 62-year-old male with a large parotid mass. The FNA smears revealed presence of extracellular, acellular amyloid-like material with tumour cells arranged in follicles.

Discussion: Awareness of cytomorphological features of these unusual variants of acinic cell carcinoma may help to avoid diagnostic pitfall.
