Microscopic evaluation for SFTs. Classic SFT with low-to-intermediate cellularity and densely collagenized, observed at (a) 100x and (b) 400x. Cellular SFT with ovoid-to-spindled cells in dense cellular proliferation arranged in a haphazard pattern in a less prominent stroma at (c) 100x and (d) 400x. Fat-forming SFTs with a variably prominent adipocytic component at (e) 100x and (f) 400x. Malignant SFTs with enhanced mitotic activity and significant cell atypia at (g) 100x and (h) 400x.
