Acinic cell carcinoma of parotid gland

Abstract

Acinic cell carcinoma (ACC) is a rare malignant tumor of the salivary glands that accounts for 6%-10% of all salivary gland malignancies. It has a propensity to considerably recur, metastasize to the lung or cervical lymph nodes. In addition, ACC can potentially be fatal. The parotid gland is where ACC most frequently begins. The purpose of this paper was to describe an unusual case of parotid gland ACC in a 58-year-old Vietnamese adult female. Before surgery, a fine-needle aspiration biopsy revealed the existence of tumor cells with acinar differentiation. Following that, she underwent successful surgery without complications. The existence of ACC was verified by the postoperative final histologic results.
