Multilocular cystic renal cell carcinoma (MCRCC), which exhibits low-stage and low-grade characteristics, is a special type of RCC. MCRCC is extremely rare and generally develops at ages >50 years. We herein report a case of MCRCC in a 28-year-old man, which, to the best of our knowledge, is the youngest case reported worldwide to date. The patient presented with irritative bladder symptoms for 1 year. Dynamic enhanced computed tomography (CT) imaging revealed a mass with inhomogeneous enhancement in the left kidney, with a rich blood supply. B-ultrasonography also revealed a renal protruding mass. As the mass was highly suspicious to be a malignant tumor, laparoscopic radical nephrectomy was performed and MCRCC was definitively diagnosed by pathological examination. The patient has been regularly followed up for 6 months, without complications or disease recurrence.
多房囊性肾细胞癌（MCRCC）是肾细胞癌的一种特殊类型，具有低分期和低分级的特点。MCRCC极为罕见，通常发生于50岁以上人群。我们在此报告一例28岁男性的MCRCC病例，据我们所知，这是迄今为止全球报道的最年轻病例。该患者出现刺激性膀胱症状1年。动态增强计算机断层扫描（CT）成像显示左肾有一个不均匀强化的肿块，血供丰富。B超检查也显示有一个肾突出肿块。由于该肿块高度怀疑为恶性肿瘤，遂行腹腔镜根治性肾切除术，病理检查确诊为MCRCC。患者已定期随访6个月，无并发症或疾病复发。
