Abstract
Schwannomas are well encapsulated mesenchymal tumors of peripheral nerves, with slow growth. The laryngeal schwanomma is exceptional, we present a case not described in the literature of shwannoma in the pre epiglottic space. A 50-year-old woman, who had a history of foreign body sensation for 4 years ago, progressing to high dysphagia and hoarseness. Direct laryngoscopy in suspension demonstrated a regular submucosal mass in the supraglottic space, reducing pharyngo-laryngeal space. CT and MRI concluded with a benign tumor of the preepiglottic space. External surgical excision was performed and a primary tracheotomy was required. The histological examination with an immunochemical study confirmed a benign schwannoma. There was no complication postoperatively. The outcome was excellent after 2 years of follow-up.Entities:
