Angiomyofibroblastoma is an uncommon benign mesenchymal tumor. It occurs mostly in the vulvovaginal area of women, but can also be observed in men. The World Health Organization, 2020, reclassified these tumors as a specific type of tumor in the category of fibroblastic and myofibroblastic tumors.[1]
The gross features of AMFB are well-circumscribed. Usually, most tumors grow slowly, and patients do not feel pain. It also has low tendency for local recurrence.
Location
edit- In women
- In men
Pathology
editMicroscopical examination shows abundant thin-walled blood vessels with hypocellular and hypercellular areas.
Immunohistochemistry
editAlmost 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.[6]
