A case of misdiagnosed leiomyoma of the vulva: A case report.

RATIONALE: Leiomyoma of the vulva is a rare, benign mass that is present on the vulva. Most commonly, they are described as painless, well-circumscribed, solitary tumors that are misdiagnosed as Bartholin cysts before surgery.

PATIENT CONCERNS: A 45-year-old woman presented with a case of vulvar leiomyoma misdiagnosed as Bartholin cyst preoperatively. A solitary swelling mass measuring 3 cm × 2 cm was found in the left labia majora at the Bartholin gland site on physical examination.

DIAGNOSES: A vulvar mass extent and vascularity may be determined by imaging. A color doppler flow imaging of the posterior vaginal wall revealed abundant blood flow.

INTERVENTION: To confirm vulvar leiomyoma, surgery and histopathology were performed.

OUTCOME: After 2 months of follow-up, there were no signs of recurrence in the patient.

LESSONS: Rare vulvar leiomyomas are often mistaken for Bartholin's cysts. It is also difficult to distinguish benign from malignant forms, making vulvar leiomyoma a difficult diagnosis. As there are a few techniques used to differentiate between the nature of the tumor, excisional biopsy seems to be the best current procedure employed in addition to being the treatment of choice for such tumors.
