RESUMO
A 44-year-old woman presented with a history of increasing left hypoacusis and sporadic vertigo. CT scan revealed a tumor occupying the mastoid, middle ear, and external auditory canal. After surgical removal, a typical secretory meningioma was diagnosed. The histological hallmark and the immunohistochemical profile of secretory meningiomas are reviewed. The differential diagnosis of this tumor in this location is also commented on. As far as we know, primary temporal bone meningiomas with secretory histology have not been previously reported in the medical literature.

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.
