Recurrent dedifferentiated liposarcoma of the spermatic cord simulating malignant fibrous histiocytoma: an immunohistochemical and ultrastructural study.

Abstract

A case of recurrent dedifferentiated liposarcoma simulating malignant fibrous histiocytoma, with complete absence of lipoblastic differentiation, is described. The tumour cells showed strongly positive immunostaining for alpha-1-antichymotrypsin. Electron microscopy revealed a mixture of fibroblasts and histiocytes. Our findings suggest that the dedifferentiated component reflects an altered differentiation pathway of the primitive mesenchymal cells in the original liposarcoma.
