Cavernous hemangiomas of the nasal cavity, which are rare, usuall y donotpresentuntiladulthood; theirincidence peaks in the fourth decade of life. Most affected patients experience epistaxis or hemoptysis and an enlarging lesion in the nose. Histologically, cavernous hemangiomas appearas closelypacked, dilated vascular channels lined with a layer offlattened endothelial cells. We describe the case of a 32-year-old man who wasadmitted to our clinic with the complaint of a nasal obstruction. On anterior rhinoscopy, hewasfound tohavea hypervascuiarizedand hypertrophied left middleturbinateand septal deviation. Computed tomography and magnetic resonance imaging oftheparanasal sinuses demonstrated awell-defined cystic lesion that hadarisen within thebonyleftmiddleturbinate and caused deviation oftheseptum to theright. Thelesion was excised via endoscopic surgery with general anesthesia. No complications occurred during the postoperative period. Histologic examination identified the tumor as a cavernoushemangioma. To thebestofourknowledge, this isthefirst case reported in the English-language literature of a cavernous hemangioma appearing asa cystic massin the middle turbinate.
The present study was designed to obtain the precise ultrastructural status of the middle ear mucosa of patients to whom ventilation tubes were applied for the treatment of secretory otitis media (SOM). This study comprised 14 children with SOM aged 5-11. Normal epithelium obtained from otosclerotic patients as controls was composed of three main cell types; basal, ciliated, and secretory. Electron microscopic observations revealed that ciliated cells were almost completely absent in the epithelium of patients with SOM. Secretory cells, on the other hand, were noted to be increased in number with cytoplasmic features indicating active secretory phase; abundant secretory granules in these cells featured both serous and mucoid characteristics. Following the application of ventilation tubes, the micrographs exhibited a vast number of ciliated cells. Furthermore, the secretory cells were less conspicuous and the secretory granules were mostly serous in type. The ultrastructural findings of this investigation strongly suggest that the application of ventilation tubes in cases of SOM stimulates ciliated cell regeneration, inhibits secretion of mucoid material, and activates serous secretion; all of which eventually shorten the recovery period.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
