Preoperative diagnosis was difficult and mainly depended on ultrasonic examination. Immunohistochemistry confirmed clear boundaries of AMFB. This condition could be completely cured by surgery, and the prognosis was good.Conclusion: The vulvar AMFB is a rare tumor that is frequently misdiagnosed before surgery. Ultrasound is preferred in auxiliary diagnosis, and surgery remains the best treatment, and long-term follow-up is necessary to avoid recurrence or other complications.Keywords: angiomyofibroblastoma, diagnosis, surgery, follow-up
