Hepatic malignant fibrous histiocytoma: CT findings.
Although malignant fibrous histiocytoma represents the most common soft tissue sarcoma in adults, its origination in visceral organs is very unusual and the liver is an exceptional site of involvement, with only 22 cases reported in the last 12 years. This controversial tumour, first described in 1964, probably originates from undifferentiated mesenchymal cells and has five different histological subtypes: storiform pleomorphic, myxoid, giant cells, inflammatory and angiomatoid. We describe herein the rather variable CT findings of three malignant fibrous histiocytomas of the liver and discuss their differential diagnosis.
