Vulvar Leiomyomatosis: A diagnostic challenge case report

Background: 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 36-year old virgin female (BMI> 30) who was referred to the clinic with 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 vulva. Continuing follow-up after treatment is highly recommended.
