BACKGROUND
Nephrogenic adenoma is an uncommon, benign metaplastic lesion occurring in the urothelium, usually as a response to chronic irritation or trauma. It is rarely encountered in hemodialysis patients. Endoscopically, these lesions can easily be mistaken for malignant tumors.
METHODS/RESULTS: We report on a case of nephrogenic adenoma of the bladder in a chronic hemodialysis patient that was large and mistakenly diagnosed as transitional cell carcinoma in the initial biopsy. Histopathological examination of the total cystectomy specimen demonstrated the correct diagnosis of nephrogenic adenoma.
CONCLUSION
Increased awareness by urologists and pathologists of nephrogenic adenoma may lead to its more accurate diagnosis.
背景
肾源性腺瘤是一种罕见的良性化生病变，发生于尿路上皮，通常是对慢性刺激或创伤的反应。在血液透析患者中很少见。在内镜检查下，这些病变很容易被误诊为恶性肿瘤。
方法/结果：我们报告了一例慢性血液透析患者的膀胱肾源性腺瘤病例，该腺瘤体积较大，在初次活检时被误诊为移行细胞癌。膀胱全切标本的组织病理学检查证实为肾源性腺瘤。
结论
泌尿外科医生和病理科医生对肾源性腺瘤的认识提高可能会使其诊断更加准确。
