Figure 4: (a) Hyper-cellular connective tissue showing spindle cells arranged in fascicular pattern. (b) Marked cellular and nuclear pleomorphism seen. (c) On immunohistochemistry, tumor was strongly and diffusely positive for desmin. (d) Shows diffusely and focally positive for MyoD1. (e) Shows diffusely and focally positive for myogenin. (f) Shows weak positivity for AE1/AE3. (g) Shows negativity for P63
