Angiomatoid malignant fibrous histiocytoma

Three cases of angiomatoid fibrous histiocytoma of the lower extremity are described. All the three patients were young and gave a history of swelling of 1-5 years duration. Histologically, the lesions were characterised by the presence of large blood filled spaces lacking endothelial lining, being surrounded and lined by sheets of proliferating histiocytes, many of which contained haemosiderin pigment.
