We report a primary vaginal angiosarcoma with widespread intra-abdominal metastasis occurring in a 73-yr-old woman 13 yr after vaginal brachytherapy for an endometrial carcinoma. This is an extremely rare phenomenon with only 7 previously reported cases of vaginal angiosarcoma, 5 of which were associated with earlier irradiation. All of the earlier reported cases have been localized to the pelvis without metastatic disease.
