Myopericytoma, also glomangiopericytoma, is a rare perivascular soft tissue tumour.
General
- Usu. benign.
- Typically in the distal extremities.[1]
Microscopic
- Fasicular pattern - may be subtle - with:
- Compressed blood vessels, often thin walled & branching.
- Increased peri-vascular cellularity.
- Cellular lesion:
- Small bland unequally spaced epithelioid/spindle cells.
- Moderate eosinophilic cytoplasm.
Notes:
- Features overlap with myofibroma.[4]
DDx:
- Solitary fibrous tumour.
- Other vascular tumours.
Images:
IHC
Features:[3]
- SMA +ve.
- CD34 +ve (focal).
