Abstract

Synchronous renal malignancies are seldom encountered or diagnosed post-renal resection. A combination of renal cell carcinoma (RCC) and urothelial carcinoma (UC) is most commonly reported. Typically, the RCC subtype is clear-cell RCC; however, a combination of collecting duct carcinoma (CDC) and UC has rarely been reported in the existing literature. Here, we present two cases of synchronous renal malignancy, specifically a combination of CDC and UC, in the ipsilateral kidney.

신장의 동시성 악성종양은 드물게 발견되며, 신장 수술 후 진단된다. 신세포암과 요로상피세포암이 함께 동반되는 경우가 가장 많이 보고 되었다. 대부분의 경우 신세포암의 아형은 투명세포형 신세포암이지만, 동시성 집합관세포암종과 요로상피세포암이 동반되는 경우에 대한 보고는 매우 드물다. 동측 신장에서 발생한 동시성 집합관세포함종과 요로상피세포암의 2건의 증례를 보고한다.
