Angiomyofibroblastoma, abbreviated AMF,[1] is rare uncommon soft tissue lesion of the vulva.
General
Clinical:[4]
- Slow growing.
- Uncommonly recur.
- Usually painless.
Clinical DDx:
Gross
- Vulvar lesion.
- Well-circumscribed.[4]
Microscopic
Features:[5]
- Hypercellular zones and hypocellular edematous zones.
- Small blood vessels (~20 micrometers) - no large blood vessels - key feature.
- Myxoid stroma - key feature.
- Small stellate cell/spindle cells without significant nuclear atypia.
DDx:
- Aggressive angiomyxoma - less cellular, large blood vessels.
Images
AMF - low mag.
AMF - intermed. mag.
AMF - high mag.
AMF - very high mag.
