Figure 2: (a) Low-power magnification showed tumour arranged in form of vague nodule with a pushing border (b) higher power magnification showed tumour cells arranged in loose fascicles over a collagenised stroma (c) individual tumour cells showed spindled nuclei, moderate nuclear pleomorphism, and moderate eosinophilic cytoplasm (d) immunohistochemistry (IHC) for vimentin showed diffuse cytoplasmic positivity in tumour cells (e) IHC for smooth muscle actin showed peripheral cytoplasmic accentuation in tumour cells (tram-track appearance), and (f) Ki-67 proliferative index was around ~10–12%
