      THE METACHRON COLON CANCER. PRESENTATION OF CASE (Abstract): Metachronous colon cancer has been described as a peculiar type of cancer, at the beginning of the 30’s, its incidence varying worldwide in the 60’s between 3 6% of the totaling colon neoplasms in the US and Europe. It is a type of secondary neoplasm in 90% of the cases, usually following another neoplastic colon lesion, being defined as a secondary neoplastic lesion appeared from 12 months to 10 years after curative surgery, in a different zone from the original neoplasm, passing unobserved on a full colonoscopy before or immediately after surgery with no pathological modification established by colonoscopy and the histopathological follow up. This is the case of 73 years old female patient, operated 8 years earlier for sigmoidian cancer. She presented with abdominal pains, the halt of the intestinal transit with gas and excrements, fecal vomit, being admitted under the diagnosis of bowel obstruction. The biochemical values have highlighted the presence of anemia, as well as a marked level of WBC (WBC = 31900), the patient being practically admitted in a toxico septic state. Intraoperatory has been revealed the presence of a malignant metacrom tumour with a hepatocolic angle, stenosant, hemorrhaging, stage IIIB, diagnosis also sustained by the histopathological exam. It has been performed a right hemicolectomy with final ileotransverse anastomosis. Post operatory evolution was good, the patient being released after 21 days post operatory. With this paper, we have two objectives: on one side, presenting a case study on metachronous colon cancer and on the other we would like to review the newest discovery in the management of the colorectal cancer and the prophylaxis of the metachronous colon cancer. The peculiarity of this case is due to the rather wide range of time free of the disease, of over 5 years and the absence of metastasis in diagnosing the metachronous tumour.
