Cystic nephroma is a rare benign multiloculated cystic renal neoplasm that is often confused with multicystic renal cell carcinoma radiographically and cytologically.
A 58-year-old woman was incidentally found to have a multiloculated cystic right renal lesion. Cytologic examination of the fluid aspirated from the lesion was reported as highly suspicious for renal cell carcinoma, but a right nephrectomy revealed a cystic nephroma.
Cystic nephroma fluid is characterized by the presence of sparse epithelial cells with moderate nuclear atypia. Conversely, the fluid of multicystic renal cell carcinoma is moderately cellular with no or mild nuclear atypia.
囊性肾瘤是一种罕见的良性多房性囊性肾肿瘤，在影像学和细胞学上常与多囊性肾细胞癌混淆。
一名58岁女性偶然发现右肾有一多房性囊性病变。对病变抽吸液进行的细胞学检查报告高度怀疑为肾细胞癌，但右肾切除术显示为囊性肾瘤。
囊性肾瘤液体的特征是存在核中度异型的稀疏上皮细胞。相反，多囊性肾细胞癌的液体细胞数量中等，无核异型或核异型轻微。
