Angiomyofibroblastoma is a non-cancerous soft tissue tumor.[1] It typically presents as a painless, slow growing mass in the vulvovaginal area of females, but can also be observed in males.[1]
The World Health Organization, 2020, reclassified these tumors as a specific type of tumor in the category of fibroblastic and myofibroblastic tumors.[2]
The gross features of AMFB are well-circumscribed. It also has low tendency for local recurrence.
Location
- In women
- In men
Pathology
Microscopical examination shows abundant thin-walled blood vessels with hypocellular and hypercellular areas.
Immunohistochemistry
Almost all tumor cells have immunoreactivity for both desmin and vimentin. It also express estrogen receptors and/or progesterone receptors, but staining for cytokeratin is negative.[7]
