Myxofibrosarcoma: a pathologico-anatomical, microangiographic and angiographic correlative study of eight cases.


A correlated angiographic, microangiographic and histological study of eight myxofibrosarcomas is presented. Myxofibrosarcoma is a very recently described type of malignant soft tissue tumour characterized by a mucoid and nodular appearance, predominantly arising superficially in the extremities and trunk in elderly people. Microscopically, the lobulated and myxoid tumours in the present series showed a characteristic plexiform network of fine capillary-like vessels and occasional wide, sinusoidal, angulated vessels. On plain radiographs they were all dense and well demarcated. Angiographically the tumours appeared highly vascular, with irregular tumour vessels often arranged in a patchy or nodular fashion. All revealed signs of a rapid circulation. The microscopic and angiographic appearances were correlated, in two cases utilizing microangiography. In the presence of a superficially located tumour with high density on plain radiographs, marked vascularity, patchy or nodular opacities, and signs of rapid circulation on angiogram one should suspect this diagnosis.
