In this case, CCS was diagnosed simultaneously with the discovery of sigmoid colon cancer and early esophageal cancer. After radical resection of sigmoid colon cancer, the patient received hormone therapy for 12 months. The symptoms such as diarrhea, hair loss, and malnutrition were relieved, and the gastric-duodenal and colonic polyp-like lesions were reduced. The early esophageal cancer was followed up for 3 years, but no active treatment was given for the early esophageal cancer. It is rare for both colon cancer and early esophageal cancer to occur simultaneously on the basis of CCS. To improve the understanding of the diagnosis and treatment of this disease and postoperative management, the case is reported as follows.  \nKEYWORDS  \nCronkhite-Canada syndrome, early esophageal cancer, esophageal cancer (EC), sigmoid colon cancer, synchronous neoplasms  \nIntroduction  \nCronkhite-Canada syndrome (CCS) is a rare non-genetic disorder characterized by multiple polyps in the digestive tract and ectodermal changes (hair loss, nail and finger/foot nail malnutrition, skin pigmentation) . It is often accompanied by diarrhea, loss of appetite, and malnutrition. The incidence of this disease is approximately one in a million. The cause is still unclear and may be related to immune abnormalities, chronic inflammation, and gene mutations. Diagnosis mainly relies on typical clinical manifestations, diffuse polypoid lesions under endoscopy, and pathological examination. Currently, glucocorticoids are the main treatment method. Some patients may need to combine immunosuppressants or endoscopic and surgical treatments. CCS is closely related to colorectal cancer. A survey in Japan indicated that the prevalence of colorectal cancer in this population was as high as 10–20%, significantly higher than that of the general population. However, CCS combined with esophageal cancer is extremely rare, and only a few reports have been published domestically and internationally. This article reports a case ofa 76-year-old male with CCS, in which both sigmoid colon cancer and early esophageal cancer were discovered atthe time  \nFrontiers in Medicine 01 [frontiers","cbCaii732XIuRjE2","https://ap.wps.com/l/cbCaii732XIuRjE2","pdf",4059906,"English","# Introduction\n# Case presentation and management\n## Diagnosis\n## Treatment and follow-up","[{\"question\":\"What is Cronkhite-Canada syndrome (CCS) and what are its typical features?\",\"answer\":\"CCS is a rare non-genetic disorder marked by multiple digestive-tract polyps and ectodermal changes such as hair loss, nail changes and malnutrition, skin pigmentation.
