a solitary fibrous tumour (SFT) is a mesenchymal tumour of fibroblastic origin that invariably displays a prominent hemangiopericytoma (HPC)-like vasculature. Currently, hemangiopericytoma (HPC) of soft tissues is a disregarded entity and is rather considered as a growth pattern, more often seen in tumours such as synovial sarcomas, malignant peripheral nerve sheath tumours, myopericytomas and SFTs. In most SFTs, tumour cells are CD34 immunopositive.1-2 Lately, signal transducer and activator of transcription (STAT)6 has been identified as a highly sensitive and specific immunohistochemical (IHC) marker for diagnosing a SFT, and a surrogate for a specific fusion gene, NAB2-STAT6, characterizing most SFTs.
