Carcinoma ex pleomorphic adenoma is not common among malignant salivary tumors and an accessory lobe of parotid gland tumor with a carcinoma ex pleomorphic adenoma histology is even rarer. Management of these tumors include a high index of suspicion, good understanding of the anatomy and a meticulous surgical access. The exceptional localization of an ossified Carcinoma ex Pleomorphic Adenoma in the accessory lobe of the parotid gland, never reported to date in the literature, has prompted us to report this case to stress the challenging difficulties related to clinical and histologic diagnosis and to analyze a minimally invasive intraoral approach.
Keywords: Accessory lobe of parotid gland; Carcinoma ex pleomorphic adenoma; Head and neck neoplasm; Minimally invasive surgery; Ossified carcinoma.
