Myxoid Liposarcomaの1例

抄録

A 53-year-old female patient with myxoid liposarcoma on the left foot is reported. The patient underwent local excisions before visiting to our hospital. The tumor had been diagnosed as benign. Physical examination revealed a 25×40mm soft cutaneous tumor which was located on the forth toe and the adjacent region of the dorsum of left foot. Light microscopy of excised lesion revealed that there were many tumor masses consisting of spindle or oval shaped cells with pleomorphic nuclei and cytoplasm containing numerous small vacuoles in the dermis and subctaneous tissue, and that tumor masses were embedded in an abundant mucoid matrix stained with Alcian blue. It was also shown that tumor masses were not completely removed at the margin of the specimens. The patient received postoperative irradiation with fast neutrons at dose of 17.1Gy. When last seen, 49months post-operatively, the patient had no evidence or recurrence or metastasis.
