INTRODUCTIONEven though colorectal cancer is one of the most frequent in the world, its simultaneous presence with other neoplasms, such as renal, is still rare in incidence. This article aims to report and expose a literature review of the synchrony of colorectal cancer and renal carcinoma. PRESENTATION OF CASEA 57-year-old female patient complaining of diffuse abdominal pain that worsened with food and improved with evacuation, especially in the periumbilical region and right iliac fossa, from moderate to strong intensity, starting 1 year ago, worsening in the last 3 months. An abdominal CT scan was performed, showing a lesion in the right kidney and a narrowing of the ascending colon lumen. Due to the possibility of cure, we opted for right colectomy and right nephrectomy at the same surgery. DISCUSSIONSynchronous tumors are neoplasms in which the diagnostic interval is up to 6 months, and must be differentiated from metachronic neoplasms and even metastases between tumors. The incidence of synchronous colorectal and renal cancer is rare but appears to be divergent. CONCLUSIONThe presence of synchronous tumors can be evidenced in imaging tests, such as CT scan, but appropriate diagnostic tests for each neoplasm, such as colonoscopy, should not be ruled out. The treatment of choice must be surgery, when possible, with the options of conventional access, videolaparoscopic and robotic surgery.
