File:3 18039322534203 sl 4.png|malignant solitary fibrous tumor | Nuclei, lacking organization, show varied size and shape, with some cells being round to ovoid. The arrow points to myxoid focus in stroma. When a majority of the following are present, a low to intermediate grade malignant solitary fibrous tumor is present: 1) size > 5 cm (this case), 2) pleomorphism with round cells/epithelioid cells (this case), 3) subcapsular hemorrhage (this case), 4) ≥4 mitoses per 10 high power fields, 5) necrosis with perivascular tumor sparing. STAT 6 positivity is very helpful in separating this tumor from its mimics | File:3 18039322534203 sl 4.png|malignant solitary fibrous tumor | Nuclei, lacking organization, show varied size and shape, with some cells being round to ovoid.
