[Kidney cancer: fortuitous discovery of a para-uterine mass at the beginning of pregnancy].

The authors relate the case of an incidental detection of a renal cell carcinoma in pregnancy. The tumor appeared as an heterogeneous adnexial mass. Special consideration for the diagnostic evaluation was taken because of pregnancy and a minimal number of CAT scan was performed. A radical nephrectomy was performed at 13 weeks. The patient tolerance, the pregnancy and postdelivery courses were as well as possible. No recurrence of the carcinoma occurred. This cas is discussed in the light of the literature.
