Krukenberg tumor of renal pelvic origin: report of a case with selected comments on ovarian tumors metastatic from the urinary tract

Int J Gynecol Pathol. 2006 Apr;25(2):147-50. doi: 10.1097/01.pgp.0000185405.08556.a0.


Metastatic tumors to the ovary are infrequently of urinary tract origin. In approximate descending order of frequency, this subset of secondary ovarian neoplasms includes renal cell carcinoma, transitional cell carcinoma of the urinary bladder, and urachal adenocarcinomas. These tumors usually raise a differential in turn of primary ovarian clear cell, transitional cell, or mucinous carcinomas. Only rare metastatic signet-ring adenocarcinomas of the bladder have shown the features of a Krukenberg tumor. We report the case of a 74-year old woman with bilateral Krukenberg tumors metastatic from a primary renal pelvic transitional cell carcinoma with glandular and signet-ring cell differentiation. This unique case reinforces that tumors with signet-ring cell morphology have a propensity to metastasize to the ovary, and indicates that renal pelvic carcinoma rarely may be the source of Krukenberg tumors.
