A – Areas of primitive neuroectodermal cells with islands of cartilage (10×, HE); B – Fascicular arrangement of spindle shaped cells with adjacent primitive neuroectodermal cells (20×, HE); C – Gland formation indicative of epithelial differentiation and focal myoid cells (10×, HE); D – Primitive neuroectodermal cells in fibrillary background with focal ganglionic differentiation (20×, HE); E – Larger "atypical" cells, with a vescicular nuclei, prominent nucleoli and moderate amount of cytoplasm (20×, HE); F – Strap cells (40×, HE); G – Admixture of primitive neuroectodermal cells and myoid differentiation of case 4 in Table 1 (10×, HE); H – Desmin immunostain highlighting striations in strap cells (40×, immunoperoxidase).
