Abstract: Pleomorphic adenoma is the most common type of all benign and malignant salivary gland tumors, involving more frequently the parotid gland. It is a benign tumor with a slow and continuous growth that without treatment can reach an enormous size. We present a case of a giant pleomorphic adenoma in a 78-year-old man with a history of more than 30 years of a growing lesion in the parotid gland. Clinical examination revealed a giant mass on the right side of the face, however without any sign of facial nerve damage. The tumor was completely resected by total parotidectomy and preservation of the facial nerve. Macroscopically, the tumor measured 28cm and weighed 4.0 Kg. On the histological examination there was a predominance of epithelial and mioepithelial cells in a hyaline and mixoid stroma. It was not found any area of malignant transformation. In the post-operatory the aesthetic and functional results were excellent.
