Mucinous and squamous cell metaplasia of the transitional cell epithelium occurs in response to chronic irritation and is predominantly found in the bladder. When the 2 forms of metaplasia occur simultaneously they usually are associated with malignancy. We report 2 cases of mucinous and squamous metaplasia of the epithelium of the renal pelvis that were not associated with malignancy. This is believed to be the fourth report of this divergent metaplasia. The mechanism for these changes is discussed.
移行细胞上皮的黏液性和鳞状化生是对慢性刺激的反应，主要见于膀胱。当这两种化生形式同时出现时，通常与恶性肿瘤相关。我们报告2例肾盂上皮黏液性和鳞状化生但不伴有恶性肿瘤的病例。据信这是关于这种不同化生的第四篇报道。文中讨论了这些变化的机制。
