Pleomorphic adenoma is the most common type of all salivary gland tumors, involving more frequently the parotid gland. In most series, it represents 45–75% of all salivary gland neoplasms. 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
