Malignant fibrous histiocytoma of the mediastinum

Abstract

A patient with malignant fibrous histiocytoma (MFH) of the mediastinum is reported. This is a very unusual site for MFH. Erosion of the thoracic aorta led to the formation of a false aneurysm, which ended fatally with rupture into the left lung. Clinical features of two other reported cases of MFH of the lung are also reviewed.
