Primary sinonasal ameloblastoma.
A case of primary ameloblastoma of the right sinonasal tract in a 66-year-old man is reported. The tumour presented as a radiographically solid mass filling the right nasal cavity and sinuses and without continuity with maxillary alveola. After radical surgery plus postoperative radiotherapy, the patient has pursued a non-aggressive clinical course after nine months of follow-up. The paper reviews the clinico-pathological features of this rare tumour and supports the theory of its sinonasal epithelium origin.
