2] Over the years this definition has been questioned and hemangiopericytoma was better considered as a diagnosis of exclusion, as it appeared that this growth pattern was non-specific, shared by numerous, unrelated benign and malignant lesions and that GPC and SFT belongs to category of lesions which are individualised within the heterogeneous group of hemangiopericytoma – like neoplasms. [

Glomus tumors involving, internal organs are very rare and most often situated in GIT. In GIT, tumors usually involve the stomach but tumor developing in the omentum have not been reported. [
