Glomangiopericytoma, also known as sinonasal-type hemangiopericytoma and sinonasal hemangiopericytoma,
Sinonasal hemangiopericytoma may be abbreviated SNHPC.[1]
General
- May be associated with oncogenic osteomalacia.[1]
- Thought to arise from the pericytes.[2]
- Rare <1% of sinonasal tumours.[2]
Microscopic
Features:[1]
- Ahort spindle cells/epithelioid cells with:
- Bland round/oval nuclei with fine chromatin.
- Scant cytoplasm.
Note:
- Superficial submucosal tissue spared.

- Phosphaturic mesenchymal tumour, mixed connective tissue type - grungy calcs, acellular matrix deposition.
- Other small round cell tumours.
