Leiomyosarcoma of the vagina is quite rare. Extensive search of the literature discloses 137 case reports published over the past 40 years. Collectively, these reports give only cursory guidelines for diagnosis, management, and prognosis. We add another case to the sparse literature on leiomyosarcoma of the vagina. Treatment consisted of surgical excision. Tumor was found to extend to the margin of the excised specimen. The malignancy quickly recurred with lung metastases and the patient died. The very poor prognosis associated with this lesion emphasizes the critical need for early diagnosis and expeditious therapy. In the interest of improving salvage by prompt recognition and intervention, it is important for health-care professionals to be knowledgeable about and alert to this condition.
