title: Angiomyoma of the retropharyngeal space.
abstract: We encountered a 59-year-old man with angiomyoma of the retropharyngeal space. He had been referred to our hospital because of a six-month history of a sensation of a narrowed pharynx. A smooth-surfaced tumour arising from the posterior wall in the hypopharynx was observed by indirect laryngoscopy. Radiographical imaging revealed a solitary tumour with homogenous contents in the retropharyngeal space. The tumour was successfully removed via a lateral pharyngotomy approach under general anaesthesia. Histopathologically, the tumour was composed of numerous veins with thick muscular walls. To the best of our knowledge, this is the first report of an angiomyoma arising in the retropharyngeal space.
