Pedunculated Angiomyofibroblastoma of Labia Minora: A Case Report and Review of the Literature

Abstract

Background: Angiomyofibroblastoma was first described by Fletcher et al. in the year 1992. It is a distinctive benign tumor that most often occurs in the superficial area of the vulva and is rarely reported in men in the inguinoscrotal region. Case Presentation: A 23-year-old female presented with a painless pedunculated labial mass which was initially pea-sized and reached 7 cm in maximum dimension over four months. The case was diagnosed on morphology, IHC and the patient was treated surgically. The interesting feature of the case was the rarity of its incidence at labia minora and pedunculated form and its resemblance to other benign and more aggressive tumours. To the best of our knowledge, the extensive English literature search revealed only seven cases of pedunculated angiomyofibroblastoma at labia majora in middleaged female and one case of labia minora in a young female. Conclusion: The lesion must be differentiated from another benign mesenchymal tumor of vulva which requires extensive surgical management.
