This report describes intraglomerular tumor cell metastases, as a rare pathologic observation. Specimens of one hundred autopsy cases (each having extrarenal carcinoma) were examined by light microscopy, and in seven of them metastatic crescents were found in the urinary space of the Bowman's capsule. The capsule itself and the layer of the parietal epithelium seemed to be intact. Glomeruli with metastases in five cases were near or inside the extraglomerular metastatic tumor mass. This phenomenon must be distinguished from metaplastic transformation of the glomerular capsular epithelium.
本报告描述了肾小球内肿瘤细胞转移这一罕见的病理学观察结果。对100例尸检病例（均患有肾外癌）的标本进行了光学显微镜检查，其中7例在鲍曼囊尿空间发现转移性新月体。囊本身和壁层上皮似乎完整。5例有转移的肾小球靠近或位于肾小球外转移性肿瘤块内。这种现象必须与肾小球囊上皮的化生转化相区分。
