Acinic cell carcinoma (ACC) is a rare type of tumor which accounts for only 1–3% of the salivary gland tumors. Majority of which occurs in the parotid gland. ACC can be misinterpreted as benign because of its low grade histology. Radiological imaging techniques have low sensitivity in detecting malignancy of parotid glands. Guided FNAC can prove to be reliable diagnostic modality that can help in differential diagnosis of salivary gland neoplasms. Aspirates from these tumors can be diagnostically challenging. The lesions that have to be considered in the differential diagnosis include a wide variety of nonneoplastic as well as neoplastic conditions and pose a serious diagnostic dilemma cytologically. Hence histopathological examination is the gold standard method of choice for diagnosing these tumors. Here we report a case of Acinic cell carcinoma of parotid gland which had cytological diagnostic dilemma and confirmed diagnosis following histopathology examination.

We describe the presentation, management, and clinical outcome of a massive acinic cell carcinoma of the parotid gland. The primary tumor and blood underwent exome sequencing which revealed deletions in CDKN2A as well as PPP1R13B, which induces p53. A damaging nonsynonymous mutation was noted in EP300, a histone acetylase which plays a role in cellular proliferation. This study provides the first insights into the genetic underpinnings of this cancer. Future large-scale efforts will be necessary to define the mutational landscape of salivary gland malignancies to identify therapeutic targets and biomarkers of treatment failure.

Abstract Dedifferentiated acinic cell carcinoma of the salivary gland is an uncommon variant of acinic cell carcinoma, characterized by the coexistence of both an usual low-grade acinic cell carcinoma and a high-grade dedifferentiated component, as well as by an accelerated clinical course. We describe a case of acinic cell carcinoma of the parotid gland in a 67-year-old woman, which recurred 4 times after surgery and radiotherapy. The recurrences consisted of residual foci of acinic cell carcinoma intermingled with a high-grade epithelial proliferation; the latter was focally constituted by cells with morphologic and immunohistochemical features of myoepithelium.
