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.
