Although both solitary fibrous tumor and hemangiopericytoma can arise in any soft tissues of the human body, including the spinal cord, the World Health Organization Classification of Tumors of the Central Nervous System (CNS WHO) assigned the combined term solitary fibrous tumor/hemangiopericytoma (SFT/HPC) to such lesions in 2016 based on the fact that both tumors share inversions at 12q13, leading to STAT6 nuclear expression [3]. This evidence concerns the gene STAT6 and hemangiopericytoma.
