title: Rare Carcinoma Ex-pleomorphic Adenoma of Buccal Mucosa: Case Report and Review of Literature.
abstract: Carcinoma ex pleomorphic adenoma (CXPA) is exceedingly rare in minor salivary glands of oral cavity. We present a case of CXPA arising from buccal mucosa in a 44-year-old male patient. The man presented to surgery outpatient department with right buccal mucosa swelling. Clinical impression suggests a neoplasm of buccal mucosa and the patient was sent for fine needle aspiration cytology. By examining the cytological smears, possibility of carcinoma was revealed. The mass was dissected and excised with safety margins. Examining Hematoxylin and Eosin slides, final diagnosis of CXPA was given. Patient did not turn for regular follow-ups and presented 1 year after surgery with recurrence at the same site. CXPA is an uncommon malignant tumor with highly aggressive biological behavior. Its occurrence in sites like buccal mucosa is rare. Hence, quite a diagnostic challenge at such sites cause diagnostic difficulties.
