肾脏非肿瘤性疾病系列(Miscellaneous Non-Neoplastic Lesions in Kidney)
多囊性肾疾病(Kidney - Multilocular Cyst )
低倍镜下见大小不等的囊肿被菲薄的纤维性隔膜分割开。囊腔内膜光滑，与肾盂不相通。
This low-power scan of the glass slide nicely illustrates the small and large cysts separated by thin fibrous septa. The cysts have smooth inner surface and do not communicate with the renal pelvis.
多囊性肾疾病
囊腔内衬以扁平样上皮。囊壁内不含有实质性肿物和肾单位。囊性肾瘤应与囊性肾癌和囊性Wilms瘤相鉴别。
The cysts are lined by flattened epithelium. Solid areas and nephronic elements are absent from cyst walls. Cystic nephroma should be distinguished from cystic renal cell carcinoma and cystic Wilms tumor.
肾脏鹿角样结石(Kidney - Staghorn Calculus)
图中可见巨大的鹿角样结石嵌顿于肾盂肾盏系统。肾下极可见出血坏死区域，伴有肾皮质萎缩。
A large staghorn calculus is seen obstructing the renal pelvi-calyceal system. The lower pole of the kidney shows areas of hemorrhage and necrosis with collapse of cortical areas.
黄色肉芽肿性肾盂肾炎(Xanthogranulomatous pyelonephritis)
下图肉眼可见，因长期化脓性炎症而出现肾实质广泛性破坏。肾下极凹陷区域是由于鹿角样结石压迫所致，结石已经取出。
This gross photograph shows extensive destruction of renal parenchyma due to long-standing suppurative inflammation. The depressions seen in the lower half of the specimen were caused by a staghorn calculus which has been removed.
黄色肉芽肿性肾盂肾炎
病例1：25岁，女性，因肾脏肿物行根治性肾切除术，病理排除癌症。病理证实为黄色肉芽肿性肾盂肾炎伴发肾周脓肿。肾内可见一直径6.0cm的腔隙性病灶，腔内表层粗糙，伴有出血。
This 25 y/o female presented with a renal mass and underwent radical nephrectomy to rule out carcinoma. The specimen revealed xanthogranulomatous pyelonephritis with a large perinephric abscess. There is a 6.0 cm cavitary lesion in the center of the kidney lined by shaggy hemorrhagic surface. It communicates with the perinephric abscess on the central lateral aspect of the specimen.

黄色肉芽肿性肾盂肾炎
病例2：70%的肾组织受到破坏。可见大量囊性扩张合并黄褐色的结石形成。中心坏死区域被致密的纤维组织所包绕。
Another case of XGP showing destruction of approximately 70% of the kidney. Numerous dilated calyces with yellow-brown calculi are seen. The central necrotic areas are surrounded by dense fibrosis. Case contributed by: Liang Cheng, MD, Dept. of Pathology, Indiana University School of Medicine, Indianapolis.
肾脏嗜酸细胞腺瘤
下图见瘤细胞巢被丰富的粘液样间质所分隔。
The tumor cell nests are separated from each other by abundant myxoid stroma.
肾脏嗜酸细胞腺瘤
瘤细胞有时也可单层或多层排列构成管状或形成小的囊腔，周围有少量基质。
The tubulocystic pattern depicted here consists of cystically dilated tubular structures separated by scant stroma.
肾脏嗜酸细胞腺瘤
