Renal medullary carcinoma is an aggressive neoplasm of the renal pelvis arising in patients with a history of sickle-cell trait. The authors report a case of renal medullary carcinoma with positive urinary cytology. Due to the location of the tumor in the renal pelvis and the loosely cohesive nature of poorly differentiated neoplasms, the presence of renal medullary carcinoma in a urinary cytology specimen is not surprising. The cytologic characteristics as well as the ultrastructural features are described.
肾髓质癌是一种发生于有镰状细胞性状病史患者的肾盂侵袭性肿瘤。作者报告了一例尿细胞学检查呈阳性的肾髓质癌病例。由于肿瘤位于肾盂，且低分化肿瘤细胞黏附性差，因此在尿细胞学标本中出现肾髓质癌并不奇怪。文中描述了其细胞学特征及超微结构特征。
