Prostatic adenocarcinoma and renal cell carcinoma (RCC) can coexist. However, the incidence of collision metastasis of both prostatic adenocarcinoma and RCC is a rare phenomenon. A 50-year-old non-smoker male with end stage renal disease and a history of prostate adenocarcinoma was noted to have a left renal mass in the upper pole during CT surveillance. With the use of immunohistochemical stains the collision of two distinct malignancies from two different topographical regions was elucidated in a retroperitoneal lymph node. We report the second known case of collision metastasis of RCC and prostatic adenocarcinoma to a retroperitoneal lymph node.
前列腺腺癌和肾细胞癌（RCC）可同时存在。然而，前列腺腺癌和RCC发生碰撞转移的情况是一种罕见现象。一名50岁、无吸烟史、患有终末期肾病且有前列腺腺癌病史的男性在CT监测期间被发现左肾上极有一个肿块。通过免疫组织化学染色，在一个腹膜后淋巴结中明确了来自两个不同解剖区域的两种不同恶性肿瘤的碰撞情况。我们报告了第二例已知的RCC和前列腺腺癌碰撞转移至腹膜后淋巴结的病例。
