The leiomyosarcoma of the vagina is extremely rare. This paper reports two observations treated at the Ibn Rochd oncology center of Casablanca. The first patient was 32 years old, and presented a tumor of 15 cm to the detriment of the posterior wall of the vagina. The treatment consisted of a large exeresis of the tumor followed by postoperative radiotherapy. After 50 months, she is still alive. The second patient who was 42 years old, had a 10 cm tumor of the posterior wall of the vagina. A tumorectomy was realized and then the patient was not heard of. The evolution was marked by the appearance of pulmonary metastasis and a palliative chemotherapy was prescribed. This patient is deceased after 31 months. Seventy-five cases only are described in the literature. The surgery is the basic treatment whereas radiotherapy is still discussed. The prognosis of these tumors remains linked especially to the histological rank.
