Preoperative cytological diagnosis of papillary cystic variant of acinic cell carcinoma: A key consideration in patient management

Abstract

Preoperative diagnosis of malignant salivary gland tumors is difficult as radiological imaging procedures have low sensitivity rate for detecting malignancy in parotid gland tumors. With careful and detailed analysis of cytological features, guided fine needle aspiration cytology can prove to be a reliable diagnostic modality that can help in differential diagnosis of cystic parotid malignancies from cystic benign tumors and non-neoplastic lesions. Papillary cystic variant of acinic cell carcinoma is a rare, cystic, primary neoplasm of salivary gland that occurs commonly in parotid .The tumor shows high local recurrence rate and has poorer prognosis compared to classic acinic cell carcinoma. Preoperative cytological diagnosis of papillary cystic variant of acinic cell carcinoma of parotid, in the case described here was the basis for adequate and timely surgical management with good results.
