Uterine Papillary Serous Carcinoma Presenting as Distant Lymph Node Metastasis

Background. Uterine papillary serous carcinomas are highly aggressive malignancies that often present with high-stage disease. We report two cases that presented initially as distant metastatic disease. One case was found incidentally at the time of axillary dissection for breast cancer and the second case in the workup of a neck mass.
