Mayer-Rokitansky-Küster-Hauser syndrome accompanied by renal cell carcinoma: a case report.

Mayer-Rokitansky-Küster-Hauser anomaly originates from agenesis of the Müllerian duct including agenesis of the uterus and the vagina because of abnormal development of the uterine ducts. This syndrome may be accompanied by the upper urinary tract anomalies such as unilateral renal agenesis, ectopia of 1 or both kidneys, renal hypoplasia, horseshoe kidney, and hydronephrosis. We report a 16-year-old girl, with unilateral renal agenesis, herniating ovary, and renal cell carcinoma in her solitary kidney, associated with Mayer-Rokitansky-Küster-Hauser syndrome-the first case in the literature to our knowledge.
