FOCAL RHABDOMYOSARCOMATOUS DIFFERENTIATION IN PRIMARY LIPOSARCOMA

A unique case of primary myxoid liposarcoma of the thigh, in which foc al pleomorphic areas were present containing rhabdomyoblasts, is descr ibed. Focal rhabdomyosarcoma in Liposarcoma has only rarely been repor ted previously and only in dedifferentiated liposarcomas of the retrop eritoneum. All but one have been recurrences with rhabdomyoblasts bein g absent in the primary liposarcoma. As rhabdomyoblasts were only foca lly present, the present case is regarded as liposarcoma with focal di vergent rhabdomyoblastic differentiation rather than malignant mesench ymoma.
