Pleomorphic adenoma of tongue: common entity at an uncommon
The present case has been reported in the Annals of Medicine & Surgery.

A 41 years old male presented to the head and neck outpatient department with a complaint of growth on the left side of the tongue that he noticed 25 days back. He also had dysphagia and difficulty in talking. On local examination, an intraoral, submucosal, solitary mass of size 2 × 1.4 cm was noted on left anterolateral aspect of tongue. It was initially small but has increased to the present size. There was no history of bleeding or any discharge from the growth or pain and sensory changes associated with it.

Surface of the growth was smooth and erythematous with surrounding mucosa appearing normal. On palpation, the size and extent were confirmed. Growth was non-tender, firm in consistency, sessile, non-fluctuant, non-reducible, compressible and non-pulsatile. No evidence of blanching was observed on digital pressure. There was no history of bleeding on palpation.

The ultrasonography of the lesion revealed a heteroechoic lesion of 2 × 1.4 cm with cystic change. Fine needle aspiration cytology (FNAC) of the mass was done which revealed round to oval benign epithelial cells embedded in dense eosinophilic chondromyxoid material. Cytological features were suggestive of a benign salivary gland neoplasm favouring the diagnosis of pleomorphic adenoma.

Subsequently, excision of the mass was performed under general anaesthesia. The histopathological examination of the specimen revealed a well-encapsulated tumor composed of islands and trabeculae of epithelial cells in chondromyxoid stroma. The postoperative period was uneventful and the patient was discharged on the 7th postoperative day and he is free of recurrence till date.

Highlights
•The salivary gland lesions pose a challenge to even the most experienced clinician and pathologist.

•Pleomorphic adenomas of the tongue are very rare accounting for 0 to 2.5% of the cases.

•The high recurrence rate and frequent malignant conversion are its characteristics features.

•High index of suspicion and an adequate clearance of the tumor is the key to successful treatment of such tumors.
