Benign Mixed Tumour Diagnosed over Fine Needle Aspiration Biopsy: A Case Report

Pleomorphic adenoma (PA) accounts for 50-70% of all salivary gland neoplasms. As the name suggests, it shows varied histological morphology. This entity accounts for about 65% of all salivary gland tumours and is well known for its exceptional ability to grow to enormous sizes if left untreated. Surgical resection is the most preferred treatment; however, the multi-nodular presentation of the tumor and incomplete resection are two challenging factors that may lead to recurrence. Optimal diagnostic measures for PAs can reduce the risk of recurrence and transformation to malignancy. We present a case of recurrent PA of the parotid gland in a 30-year-old female patient who was diagnosed 5 years ago, treated, and is now diagnosed with the same by a fine-needle aspiration biopsy.
