title: Renal cell carcinoma in a horseshoe kidney presenting as an acute, left sided varicocele.
abstract: We present a rare case of renal cell carcinoma (RCC) in a horseshoe kidney presenting as an acute left sided varicocele. A left sided varicocele is a well-described presentation of RCC, usually caused by tumour thrombus extending along the renal vein with resultant testicular vein occlusion. However, in our case a tumour in the lower pole of a horseshoe kidney caused an acute varicocele by direct involvement and occlusion of the testicular vein.
