Abstract

This a case of 40 years old male presenting to our department with a large swelling in the left side of neck associated with dragging sensarion. After clinical evaluation it wsa a giant  smass in left submandibular margin extending tupto 4th intercostals space.MRI neck showed a heterogenous soft tissue mass embedding left parotid and  its parietal  plane with slight compression and displacement of great vessels. FNAC indicated pleomorphic Adenoma of parotid gland. The patient ultimately underwent resection of the mass, which measured 26 cm in diameter, weighed 7.5 kg, and proved on pathologic examination to be a benign mixed tumor without malignant degeneration. Management of this unusual tumour is discussed, and the literature on giant parotid tumours is reviewed.
