A unique case of primary myxoid liposarcoma of the thigh, in which focal pleomorphic areas were present containing rhabdomyoblasts, is described. Focal rhabdomyosarcoma in liposarcoma has only rarely been reported previously and only in dedifferentiated liposarcomas of the retroperitoneum. All but one have been recurrences with rhabdomyoblasts being absent in the primary liposarcoma. As rhabdomyoblasts were only focally present, the present case is regarded as liposarcoma with focal divergent rhabdomyoblastic differentiation rather than malignant mesenchymoma.
本文描述了一例罕见的大腿原发性黏液样脂肪肉瘤，其中存在含有横纹肌母细胞的局灶性多形性区域。脂肪肉瘤中局灶性横纹肌肉瘤此前仅有极少报道，且仅见于腹膜后去分化脂肪肉瘤。除1例之外，其余均为复发病例，原发性脂肪肉瘤中不存在横纹肌母细胞。由于横纹肌母细胞仅局灶性存在，故本病例被视为具有局灶性异向横纹肌母细胞分化的脂肪肉瘤，而非恶性间叶瘤。
