肾血管平滑肌脂肪瘤(angiomyolipoma,AML)伴发透明细胞性肾细胞癌(clear cell renal cell carcinoma,CCRCC)为罕见疾病,于1975年由Kavaney等[1]首次报道,至今英文文献报道40余例,国内仅见数例个案报道。两种肿瘤发生在同侧肾脏,可相互孤立形成复合瘤,亦可相互掺杂形成碰撞瘤。AML和CCRCC均可为单灶性或多灶性,其中,AML为多灶性者更为罕见。迄今,国外报道58例ALM伴发肾恶性肿瘤,47例伴发CCRCC的病例
Renal angiomyolipoma (AML) is a rare disease associated with clear cell renal cell carcinoma (CCRCC). It was first reported by Kavaney et al [1] in 1975, and more than 40 cases have been reported in English literature , Only a few cases reported in China. Two kinds of tumors occur in the ipsilateral kidney, can form a complex tumor isolated from each other, can also be doped with each other to form a collision tumor. AML and CCRCC can be single or multifocal, of which, AML multifocal are more rare. So far, foreign reports of 58 cases of ALM associated with renal cancer, 47 cases of patients with CCRCC
