We believe this to be the third reported case of an unusual congenital sacral tumor-like lesion characterized histologically by the presence of dysplastic and immature renal-like tissue with a predominant glomerular and tubular structure. This lesion appears important in the differential diagnosis of extrarenal nephroblastoma, and should be regarded as a dysplastic overgrowth. An origin from mesonephric or metanephric remnants is suggested.
我们认为这是第三例报告的罕见先天性骶骨肿瘤样病变，其组织学特征为存在发育异常和不成熟的肾样组织，以肾小球和肾小管结构为主。该病变在肾外肾母细胞瘤的鉴别诊断中似乎很重要，应被视为发育异常性过度生长。提示其起源于中肾或后肾残余。
