Rhabdomyoma of the larynx: a review of the literature with a summary of previously described cases of rhabdomyoma of the larynx and a report of a new case.
A review of extracardial rhabdomyomas of the larynx reported in the literature is presented. A new case is added (the largest described yet). The diagnosis was based on routine histological and immunohistological staining, and electron microscopy. The extracardial rhabdomyomas were divided into three types according to histopathological findings: (i) adult; (ii) foetal cellular type; and (iii) foetal myxoid. There are 23 well-documented cases (including this case) of extracardial rhabdomyomas of the larynx; 15 of the adult type, four of the foetal myxoid type and four of the foetal cellular type. The differential diagnosis and the requisite diagnostic procedure is discussed. The tumour is benign. The treatment is surgical excision. Although rare, its existence should be kept in mind in the differential diagnosis of laryngeal tumours.
