Benign vascular tumours of the Mediastinum: presentation of three cases and review of the literature.

Two patients with epithelioid haemangioendothelioma and one patient with multiple cavernous haemangiomas of the mediastinum, pharynx and larynx, are herein presented. Haemothorax as initial manifestation of the tumour was observed in one of them. Epithelioid haemangioendotheliomas were radically removed in both cases. Because of the absence of a well defined capsule and the huge extension, the cavernous mediastinal haemangioma was not resected. However the patient was successfully treated by administration of corticosteroids. Clinicopathologic characteristics of these benign forms of vascular tumours are discussed and treatment options are suggested.
