Abstract:
Oncocytic carcinoma of the salivary gland is an uncommon tumour in the head and neck region.
Owing to its rarity, identifying the histopathological features of a malignant tumour can be difficult
and challenging. We report a case of a 70-year-old man who presented with a left facial weakness
for six months in a background history of left parotid swelling over the past 10 years. Clinical
examination revealed a 3x3cm left parotid mass and grade 4 facial nerve palsy. Fine needle aspiration
of the mass showed scattered cohesive, monolayered sheets of uniform oncocytic cells. Subsequently,
a left total parotidectomy and selective neck dissection were performed. Histological examination
showed sheets of small oncocytes with minimal nuclear atypia. Evidence of nerve entrapment,
capsular invasion and perivascular permeation were identified in focal areas. Thus, a final diagnosis
of oncocytic carcinoma was rendered.
