BACKGROUND
Metastasis of renal cell carcinoma (RCC) to the skeletal muscle and small bowel is an exceedingly rare occurrence. Both of these sites are unusual sites for RCC to metastasize to and to occur simultaneously is even less common.
CASE SUMMARY
A 58-year-old male with known history of RCC presented with a recurrence that was diagnosed through imaging and biopsies. Mucosa abnormalities of small bowel noted during endoscopy were biopsied as well as lesion in the psoas muscle that was noted.
CONCLUSION
This case report emphasizes that RCC can not only recur but can do so even decades later and present as metastatic foci at atypical sites.
背景
肾细胞癌（RCC）转移至骨骼肌和小肠极为罕见。这两个部位都是RCC不常见的转移部位，同时发生转移的情况更为罕见。
病例摘要
一名有RCC病史的58岁男性出现复发，通过影像学检查和活检确诊。在内镜检查中发现的小肠黏膜异常以及腰大肌病变均进行了活检。
结论
本病例报告强调，RCC不仅可以复发，甚至在数十年后仍可复发，并表现为非典型部位的转移灶。
