Multilocular cystic renal cell carcinoma (MCRCC) has been identified as a separate subtype of renal cell carcinoma (RCC) in the 2004 World Health Organization classification of adult renal tumors. MCRCC represents a rare variant of clear cell RCC. The common age group for this tumor is between 40 and 60 years. In our case, MCRCC occurred at the age of 23 years in a female patient. We report this case because of its rarity in this age group, sex, good prognosis, and also to avoid a misdiagnosis as conventional clear cell RCC. However, before making a diagnosis of MCRCC, it has to be differentiated from tubulocystic carcinoma, cystic nephroma, cystic clear cell carcinoma, and clear cell papillary RCC.
多房性囊性肾细胞癌（MCRCC）在2004年世界卫生组织成人肾肿瘤分类中被确定为肾细胞癌（RCC）的一个独立亚型。MCRCC是透明细胞RCC的一种罕见变体。该肿瘤的常见年龄组在40至60岁之间。在我们的病例中，一名23岁女性患者发生了MCRCC。我们报告此病例是因为它在这个年龄组、性别中罕见，预后良好，同时也是为了避免误诊为传统透明细胞RCC。然而，在诊断MCRCC之前，必须将其与肾小管囊性癌、囊性肾瘤、囊性透明细胞癌和透明细胞乳头状RCC相鉴别。
