Pleomorphic adenoma of parotid gland with extensive bone formation – A rare case report

We report an unusual case of a huge tumor that measured 9×8cm & 400g by weight with extensive bone formation, occurring in the parotid gland of a 22year old man. Thorough clinical examination was done. FNAC was done which showed Myxochondroid matrix with glandular epithelial cells suggesting pleomorphic adenoma. CT scan head & neck revealed a large mass with nodular areas of calcification within soft tissue with marked narrowing of orophayngeal lumen. Total parotidectomy with preservation of facial nerve was done by the Transcervical Transparotid approach. The histopathological findings suggested the possibility of extensive endochondral ossification in pleomorphic adenoma. Preservation of facial nerve functions is a key to successful parotid surgery.
