Primary mucinous adenocarcinoma of minor salivary glands of the palate: Case report and literature review

Primary mucinous adenocarcinomas of salivary glands are very uncommon tumors. This tumor is generally localized in minor salivary glands and has usually an aggressive behavior. We present the case of a 47-year-old man with an extensive tumor in the palate, left maxillary sinus, nasal cavity and sphenoid, developed along a period of 6 months. A maxillectomy was performed and mucinous adenocarcinoma was diagnosed. Despite the rapid growth of the lesion, 20 months after surgery the patient showed neither metastasis nor local recurrence.
