CCSK is a rare type of renal neoplasm in childhood and its diagnosis relies mainly on histopathology and immunohistochemistry. It is important to be familiar with the morphological variants of CCSK to avoid confusion with other similar lesions, such as Wilm's tumor, congenital mesoblastic nephroma, malignant rhabdoid tumor of kidney, primitive neuroectodermal tumor.
CCSK是一种罕见的儿童期恶性肾肿瘤，诊断主要依靠组织病理学和免疫组化，熟悉其形态学变异有利于与其它类似病变如肾母细胞瘤、先天性中胚叶肾瘤、肾恶性横纹肌样瘤、原始神经外胚叶肿瘤等鉴别。

endoderm：内胚叶
外胚叶(ectoderm)为临近滋养层的一层柱状细胞,内胚叶(endoderm)是位居胚泡腔侧的一层立米细胞,两层紧贴在一起. 继之,在外胚叶的近滋养层侧呈现一个腔,为羊膜腔,腔壁为羊膜. 羊膜与外胚叶的周缘续连,故外胚叶构成羊膜腔的底.

epiblast：外胚叶
它通常呈鞘状与外胚叶(epiblast)分离开来,单纯成为幼根的保护器官. 但在水稻等植物中它与外胚叶的区别并不明显,因此,莫如把这部分看作是胚的器官中尤其是幼根出生时前胚组织的残留部分较为妥当.
