A Rare Case of Vaginal Leiomyoma: A Case Report and Review of Literature

Leiomyomas are benign tumors of the female genital tract, usually arising from the uterus. Vaginal leiomyomas are extremely rare. We describe here a case of vaginal leiomyoma in a 28-year-old unmarried woman who presented with excessive vaginal bleeding and acute retention of urine. Magnetic Resonance Imaging (MRI) helped in diagnosing the vaginal origin of the mass. It was treated by complete excision through the vaginal route and repair of the vaginal defect. Injection adrenaline was used in 1:200000 dilution to identify the tumor extent and create an avascular plane for safe enucleation of the myoma. Post-surgery, the patient recovered well, with good healing of the vaginal wound and complete recovery from voiding difficulty. Histopathology was suggestive of benign vaginal leiomyoma. Thus though rare vaginal leiomyomas should be considered in the differential diagnosis of benign vaginal tumors, they are best identified by imaging modalities like transvaginal ultrasonography (TVS) and MRI. Vaginal myomectomy with repair of the vaginal defect is the most prevalent and conventional method of treatment. The diagnosis is confirmed by histopathological examination of the excised tumor.
