Vaginal Cellular Angiofibroma: Report of a Rare Case with Literature Review.

Cellular angiofibroma (CA) is a relatively recently described, rare, benign soft tissue tumor that predominantly occurs in the vulvoperineal region. It was first described in 1997 as a mesenchymal-origin tumor composed of connective (fibrous) tissue and blood vessels. We report a case of vaginal CA in a 40-year-old woman who presented with pressure symptoms, incidentally diagnosed with a vaginal mass and clinically suspected as vaginal myoma. This case was diagnosed based on histomorphology and immunohistochemistry and underwent surgical treatment. This tumor was a diagnostic dilemma for other benign and aggressive spindle cell tumors in the same area, such as endometrial stromal nodule, spindle cell lipoma, solitary fibrous tumors, and mixed tumors of the vagina.
