肾脏黏液性小管状和梭形细胞癌(MTSCs)是一种多形性肿瘤,由内衬立方上皮的小管、长管和(或)梭形细胞条索组成,间隔黏液样基质。尽管文献从不同角度描述了一系列有关该肿瘤的免疫组化表型、超微结构特征、遗传学变异和短期临床随访等,但MTSCs中可能出现的形态学改变的程度还不是 Mucinous tuberculous and spindle cell carcinomas (MTSCs) in the kidney are pleomorphic tumors consisting of tubules, long tubules and (or) spindle-cell cords lined with cubic epithelium that divide the myxoid-like matrix. Although the literature describes a series of immunohistochemical phenotypes, ultrastructural features, genetic variations, and short-term clinical follow-up of the tumor from different perspectives, the extent of morphological changes that may occur in MTSCs is not yet
