Abstract
We discuss the morphological, immunohistochemical and electron-microscopical features of a malignant myxoid liposarcoma which appeared in the left thigh of a 52-year-old woman. The cytogenetic analysis following short-term tissue culture confirmed the existence of a nonrandom translocation t(12;16)(q13;p11). Furthermore, immunohistochemistry showed positivity for S-100 antigen and vimentin, both of which are considered to be markers for liposarcoma. The electron-microscopical study revealed a close contiguity between the tumoral cells and atypical pericytes.
