Vulvar Leiomyomatosis: A Diagnostic Challenge Case Report

Abstract

Introduction: Vulvar leiomyomas are rare and usually misdiagnosed as Bartholin's cyst on initial presentation. Leiomyoma of vulva accounts for only 0.03 of all gynecological neoplasm. Definite diagnosis is based on surgical excision of the tumor. The aim of this report is to introduce a case of leiomyoma of the vulva which was initially misdiagnosed as Bartholin's cyst. Case Presentation: We present a case of a 36-year old virgin female (BMI>30) who was referred to the clinic with a 5-year history of left labial mass which was initially diagnosed as Bartholin's cyst. The mass was removed and the pathologist confirmed that the final diagnosis was vulvar leiomyoma. Conclusion: Vulvar leiomyoma is usually misdiagnosed with Bartholin cyst and distinguishing between benign and malignant forms is confusing, so it is a diagnostic challenge. Surgical excision is the treatment of choice in all smooth muscle tumors of the vulva. Continuing follow-up after treatment is highly recommended.
