[A case of multifocal colon carcinoma and cholecystolithiasis in an elderly patient]

An 83-year-old woman was admitted to our hospital because of general fatigue and symptoms of anemia. For 20 years, she had experienced right hypochondrial pain several times a year. Colonoscopic examination revealed a type 2 tumor at the ascending colon. The biopsy specimen was a Group 5 and type 0-IIa polyp at the transverse colon. The endoscopic mucosal resection (EMR) specimen was a well-differentiated adenocarcinoma(Stage pSM [2mm], ly0, v0). An apple core lesion in the cecum was detected by enema. Abdominal computed tomography demonstrated cholecystolithiasis and no metastasis or distant metastases. Therefore, a diagnosis of multifocal colon carcinoma and cholecystolithiasis was made. Expanding right hemicolectomy with cholecystectomy was performed. The patient was discharged without any complications. Subsequently, she underwent adjuvant chemotherapy for 6 months. At present, 1 year after surgery, the patient is still alive and has shown no signs of recurrence.
