Nephrogenic adenoma: clinicopathological and immunohistochemical analyses
摘要
Abstract
Purpose To analyze the clinicopathological and immunohistochemical features of nephrogenic adenoma ( NA ) in the urinary tract. Methods Five cases of nephrogenic adenoma in the urinary bladder and ureter were evaluated by histopathology and iminuno-histochemistry with review of the literature on its etiology, pathogenesis, and clinicopathological features. Results Three of the cases were from the urinary bladder and two from the ureter. The lesions appeared as a mucosal papillary or polypoid mass macroscopically, and were consisted of tubules, cysts or papillary structures lined by cuboidal, flat, or hobnail-like epithelial cells microscopically. Immunohistochemical staining showed that the epithelial cells were positive for PAX2, CK7, EMA, and AMACR/P504S, but negative for PSA, CD10, p63 and CD31. The Ki-67 labeling index was less than 2% . Conclusions Nephrogenic adenoma is a rare tumor-like lesion that may be misdiagnosed as epithelial tumors such as adenocarcinoma. Awareness of the entity and familiarity with its clinicopathological and immunohistochemical features are the keys to the correct diagnosis.关键词
