Primitive neuroectodermal tumor (PNET) is usually an aggressive, rapidly progressing and metastasizing tumor. Occurrence of this type of tumor in the kidney is considered as unusual and few cases have been reported so far. We present a metastatic PNET arising probably from the kidney in a 17-year-old female patient with local invasion and metastasis to the stomach. PNET should be considered as a differential diagnosis of a large heterogeneous soft tissue mass in the abdomen, especially in those with widely local invasion and metastases.
原始神经外胚层肿瘤（PNET）通常是一种侵袭性强、进展迅速且易转移的肿瘤。这种类型的肿瘤发生在肾脏被认为是不寻常的，迄今为止报道的病例很少。我们报告了一名17岁女性患者，其转移性PNET可能起源于肾脏，伴有局部侵犯和胃转移。PNET应被视为腹部巨大异质性软组织肿块的鉴别诊断之一，尤其是那些伴有广泛局部侵犯和转移的病例。
