Four cases of angiomatoid malignant fibrous histiocytoma (AMFH) are reported. Microscopically and ultrastructurally
the AMFH was composed of various tumor cells. of the 4 cases
three were stained with α1-AT and α1-ACT by PAP method
one stained with factor Ⅷ. Histologic features showed vascular tumor with malignant fibrous hitiocytoma. Our study supports the concept that the tumor arises from primitive mesenchymal cells that are capable of differentiating toward different cell lines
