Abstract：
Renal oncocytoma is a benign renal neoplasm which has mostly been reported in adults. Occurrence in children is infrequent. To date, there are only six pediatric cases of renal oncocytoma reported previously. Herein, we report a 13-year-old girl presented with hematuria for a week. Abdominal computed tomography showed a well-defined heterogeneous solid mass with a stellate central scar in the left kidney. The patient underwent a nephron sparing surgery. Histopathological and immunohistochemical findings confirmed the diagnosis of renal oncocytoma. Though uncommon, renal oncocytoma should be considered as the differential diagnosis of renal tumor in children. In addition, intranuclear inclusions were firstly described in this pediatric patient with unclear significance, which need a large cohort to summarize and analyze.
摘要：
肾嗜酸细胞瘤是一种良性肾脏肿瘤，主要在成人中报道。儿童很少发生。迄今为止,以前报道的儿童肾嗜酸细胞瘤只有6例。在这里，我们报告一名13岁女孩出现血尿一周。腹部计算机断层扫描显示左肾脏有一个明确的异质固体块，带有星状中央疤痕。患者接受了保留肾单位的手术。组织病理学和免疫组织化学结果证实了肾嗜酸细胞瘤的诊断。虽然不常见，肾嗜酸细胞瘤应作为儿童肾肿瘤的鉴别诊断。此外,首先在这名儿科患者中描述了核内包涵体，但意义不明确，这需要一大群人来总结和分析。
