However, given the morphologic similarities between fibrous soft tissue tumors and fibrous pseudotumors particularly the extensive hyalinization, sclerotic changes, and a hypocellular spindle cell mass with tapered nuclei-consultation with additional in-house pathologists were made to consider excluding a solitary fibrous tumor (SFT) using signal transducer and activator of transcription 6 (STAT6) despite the absence of variable cellularity and prominent staghorn vascular structures. Here, STAT6 is linked to solitary fibrous tumor.
