Malignant fibrous histiocytoma presenting as an endobronchial polyp of the carina

Abstract

A 64 year old man was admitted to hospital due to dyspnoea and stridor. A peduncular polyp of the carina was found at bronchoscopy. Histological examination of the tumour after resection with endoscopic electronsurgery revealed malignant fibrous histiocytoma (MFH) of myxoid type. With endoscopic neodymiumyttrium aluminium garnet (Nd-YAG) laser surgery, residual tumour was eliminated. To our knowledge this is the first case with malignant fibrous histiocytoma appearing as a polyp of the carina.
