Secondary jejunal tumor from renal cell carcinoma (RCC) is extremely rare in clinical practice and is easily missed and misdiagnosed because of the low incidence and atypical symptoms.
A 38-year-old male patient was diagnosed pathologically with left RCC after radical nephrectomy in 2012. The patient then suffered multiple lung metastases 2 years later and was treated with oral sorafenib without progression for 6 years. In 2020, an emergency intestinal segmental resection due to intestinal obstruction was required, and postoperative pathology confirmed a jejunal secondary tumor from RCC. The patient had a smooth recovery following surgery. Three months after surgery, the patient was diagnosed with left adrenal metastasis, and subsequent sintilimab therapy has stabilized his condition.
This report is written to remind urologists and pathologists of the potential for small intestinal secondary tumors when a patient with a history of RCC seeks treatment for digestive symptoms. Enteroscopy and abdominal contrast-enhanced computed tomography are essential means of examination, but severe cases require immediate surgical intervention despite the lack of a preoperative examination to distinguish tumor attributes.
Core Tip: Jejunal secondary tumor from renal cell carcinoma (RCC) is extremely rare. Herein, we present a case of small bowel obstruction caused by a jejunal secondary tumor from RCC. A male patient who underwent a left radical nephrectomy for RCC before visited the hospital with intestinal obstruction symptoms. Emergency intestinal segmental resection was performed, and postoperative pathology confirmed a jejunal secondary tumor from RCC. This report is written to remind urologists and patho
