Phosphotungstic acid-hematoxylin staining and Masson staining show cytoplasmic striae, crystals, and rod inclusions in the tumor cells, while immunohistochemical analysis shows S-100 (−), desmin (+), and myogenin (+); (5) lipoblastoma: it is commonly found in infants and young children and shows mature adipocytes and lipoblastoma in various stages of differentiation; and (6) myxoid liposarcoma: it is commonly found in the elderly and shows hypervascularity, a prominent “plexiform” capillary pattern, and the characteristic molecular translocation t (12; 16) (q13; p11) [28]. The gene discussed is DES; the disease is lipoblastoma.
