Unusual Location for Common Tumor‒Vulvar Leiomyoma in a 40-Year-Old Woman: A Case Report and Review

Abstract

Leiomyomas are common benign smooth muscle tumors of the uterus; their presentation in the vulva is rare and tends to impose diagnostic challenges, mistaken for other conditions. A forty-year-old, perimenopausal, unmarried patient attended our clinic complaining of a slowly growing vulvar mass for the last 6 months. General evaluation and past medical history were unremarkable. Upon local examination, a firm, non-tender vulvar mass measuring 3 × 4 cm was found, causing discomfort during walking. Preoperative lab investigation and ultrasonography suggested a benign tumor. The patient was advised to undergo surgical excision, which was done under general anesthesia. Histopathology confirms the case. Postoperative recovery was uneventful; she was followed every 6 months;  no recurrence after 5 years of follow-up. Vulvar leiomyomas, although rare, should be excluded in a vulvar mass. Definite diagnosis requires histopathological confirmation. Surgical excision of the whole mass provides effective treatment and a better prognosis.
