[Hemangiopericytoma of the larynx].

Only 9 cases of haemangiopericytoma of the larynx have been described so far in international literature. In the present paper the tenth case is reported. This report concerns a woman patient of 79 years of age suffering from haemangiopericytoma localised on the left aryepiglottidian fold and in the laryngeal wall of the left piriform sinus. Generally, the histopathological diagnosis of this type of tumour presents problems, in particular the differential diagnosis to glomus tumours and haemangioendotheliomas. Haemangiopericytoma is considered to be a malignant tumour, and hence the tumour must be extirpated as radically as possible while protecting the organ system. It is recommended to provide for regular clinical control of these patients. In our case we could extirpate the complete tumour radically via lateral pharyngotomy, protecting the larynx and its function. In addition, we performed cricopharyngeal myotomy to prevent postoperative deglutition disorders. 6 months postoperatively the patient is symptom-free and up to now there is no local recurrence of the tumour.
