Pre-aortic lymphadenopathy after nephroureterectomy for transitional cell carcinoma of the renal pelvis: Unexpected histological results

Abstract

A patient underwent nephroureterectomy for transitional cell carcinoma of the renal pelvis (pT3 G3 N0 M0). After 5 years a CT scan showed a retroperitoneal lymphadenopathy, suspected of being a metastasis. Histological examination of the surgically-removed lymph node showed seminoma. Palpation of the testes was negative. Testicular ultrasonography showed three hypoechoic areas in the right testis. Orchiectomy was subsequently performed and the histological examination of the testis confirmed the presence of seminoma (pT1).
