Cystic partially differentiated nephroblastoma is a multilocular cystic variant of Wilms tumor that always presents in children. However, we encountered an elderly patient with cystic partially differentiated nephroblastoma. Therefore, we report it.
A 74-year-old male presented with a left renal tumor detected with ultrasonography. Contrast-enhanced computed tomography and magnetic resonance imaging revealed a 4 cm multilocular cystic tumor with septa, which suggested multilocular cystic renal cell carcinoma. Therefore, we performed a radical nephrectomy. The definitive diagnosis of cystic partially differentiated nephroblastoma was made with histopathological findings. After the surgical resection, no recurrence has occurred in the past 13 years.
Cystic partially differentiated nephroblastoma can develop in adults, regardless of age. Furthermore, surgical resection can be used as an established treatment option in adult cystic partially differentiated nephroblastoma cases.
囊性部分分化型肾母细胞瘤是肾母细胞瘤的一种多房囊性变体，多见于儿童。然而，我们遇到了一位患有囊性部分分化型肾母细胞瘤的老年患者。因此，我们将其报告如下。
一名74岁男性因超声检查发现左肾肿瘤就诊。增强计算机断层扫描和磁共振成像显示一个4厘米的多房囊性肿瘤，有分隔，提示多房囊性肾细胞癌。因此，我们进行了根治性肾切除术。根据组织病理学结果确诊为囊性部分分化型肾母细胞瘤。手术切除后，在过去13年中未出现复发。
囊性部分分化型肾母细胞瘤可发生于成年人，与年龄无关。此外，手术切除可作为成人囊性部分分化型肾母细胞瘤病例的既定治疗选择。
