A case of lipoblastomatosis occuring in a 1 year and 10 month old boy is described. The tumor was first presented in the left foot at his age of 4 month, and was surgically removed. The tumor was grossly infiltrating skeletal muscle tissue, and was microscopically composed of lobulated fat tissue with prominent myxoid stroma and many immature mesenchymal cells and scattered multivacuolated lipoblasts. The tumor recurred 11/2 years later and was again removed. The tumor was equally lobulated and located inbetween skeletal muscle. However, this time lobulated tumor consisted almost entirely of mature fat tissue with scattered lipoblasts.
