Presentation of renal cell carcinoma as cervical polyp metastasis.

Secondary cervical adenocarcinomas are most commonly seen owing to the extension of a primary endometrial adenocarcinoma. Metastatic tumors from other sites are rather uncommon and, when seen, are most frequently from the ovaries, gastrointestinal tract, or breast. We report a case of metastatic renal cell carcinoma, clear cell variant, to the cervix, which presented as a cervical polyp in a postmenopausal female. To our knowledge, this is the fourth reported case of renal cell carcinoma metastatic to the cervix. This case is only the third in which the cervical metastasis was the presenting sign of renal cell carcinoma and the first in which the clinical presentation was as a cervical polyp.
