In this study 208 patients with adenocarcinoma of the uterine cervix were examined for the occurrence of tumors metastatic to this location. A total of 45 secondary tumors were found, 31 with a primary endometrial tumor, 6 with an ovarian serous or mucinous adenocarcinoma, 2 tubal tumors, 5 colonic adenocarcinomas, and 1 primary mammary tumor. Clinical and morphological aspects were studied, indicating the need for consideration of metastatic tumors as explanation for suspected neoplastic cervical lesions.
