Wilms' tumor is the most common malignant solid tumor of the kidneys in children. Extrarenal Wilms' tumor is extremely rare. Herein, we report an 8-month-old boy with a chief complaint of frequent micturition and dysuria for 10 days. Physical examination and ultrasonography evaluation revealed simultaneous involvement of neoplasms in the left kidney and the bladder. Following excision of the masses, both were identified as Wilms' tumor by histopathology and immunohistochemistry. The two neoplasms are presumed to have developed independently because of the different pathological manifestation.
肾母细胞瘤是儿童最常见的肾脏恶性实体瘤。肾外肾母细胞瘤极为罕见。在此，我们报告一名8个月大的男童，主要症状为尿频、尿痛10天。体格检查和超声评估显示左肾和膀胱同时有肿瘤累及。肿物切除后，经组织病理学和免疫组化检查，二者均确诊为肾母细胞瘤。由于病理表现不同，这两个肿瘤被认为是独立发生的。
