[Vaginal metastases of breast cancer].

Metastases to the vagina from breast carcinoma are uncommon, and are most often detected during autopsies of patients who have died from a breast cancer or from metastases to the genital tract. A case of symptomatic vaginal metastasis secondary to bilateral breast carcinoma is reported. The potential routes of dissemination include lymphatic and vascular spread. Their respective frequencies vary in the literature. Lymphatic spread in this case is suggested by demonstrable ovarian, myometrial, and lymph node involvement associated with massive submucosal vaginal involvement. This observation of concomitant visceral and lymphatic spread improves our knowledge of metastatic spread from breast cancer to the female genital tract by the lymphatic route.
