[Epiglottic cysts: an unsuspected cause of dysphagia. Anatomo-clinical study and treatment options].

Laryngeal cysts represent a defined group of benign lesions with an actual not well know pathogenesis although fibrosis and glandular obstruction or congenital origin are presumed rather than new growths. When such cysts occur, as a general rule, with the exception of some particular locations, they develop with very few symptoms until very large size is reached or a fast growth is produced due to bleeding or infection. Under these conditions, these cysts may represent a potential treatening lesion and so surgery is recommended under any circunstance and anaesthetic procedure should be case-addapted. A case of an impressive large epiglottic cyst is presented and a revision and discusion on the controversies and available literature are provided.
