Renal cholesteatoma is an extremely uncommon disease. The renal pelvis is the most common site, but the lesion can be localized, even if rarely, in a calix or in the ureter. Histologically it consists of a keratinizing desquamative squamous metaplasia, with absence of cellular atypia in the urothelium, therefore cholesteatoma is not considered as a premalignant lesion. Authors report a case of renal cholesteatoma and take into consideration particularly the question regarding the diagnostic approach, that in spite of the help of new imaging techniques, as TC, is unable to arrive at a certain diagnosis, and the therapeutic approach, that must be conservative, when it's possible and according to the majority of Authors.
肾胆脂瘤是一种极其罕见的疾病。肾盂是最常见的部位，但病变也可局限于肾盏或输尿管，尽管这种情况很少见。组织学上，它由角化性脱屑性鳞状化生组成，尿路上皮无细胞异型性，因此胆脂瘤不被视为癌前病变。作者报告了一例肾胆脂瘤病例，并特别考虑了诊断方法的问题，尽管有计算机断层扫描（CT）等新的成像技术的帮助，但仍无法做出明确诊断；还考虑了治疗方法的问题，即根据大多数作者的观点，在可能的情况下必须采取保守治疗。
