Metastatic renal cell carcinoma (RCC) presenting with peritoneal involvement or ascites is rare and has been previously described clinically in the setting of large renal mass or other distant metastases. We report an unusual case of RCC presenting with ascites without large mass or other distant metastases. Advances in cytologic diagnosis of metastatic RCC in serous ascitic fluid is discussed, while a potential mechanism of tumor spread is presented.
转移性肾细胞癌 (RCC) 表现为腹膜受累或腹水是罕见的，以前曾在大肾肿块或其他远处转移的情况下临床描述过。我们报告了一例不伴有大肿块或其他远处转移的 RCC 伴腹水的不寻常病例。讨论了在浆膜性腹水的转移性 RCC 的细胞学诊断方面的进展，同时提出了肿瘤扩散的潜在机制。
