This cases accounted for 1.1% of total biopsies submittedto the departement during the study period.The mean age for Malignant colorectal neoplasms was 48 years. The mean age for each histologic type was analyzed.The youngest case seen was 15years of age. The male:female ratio was 1.3:1.Of all CRC 59.7% occurred in the rectum & sigmoid. The most frequent histologic type was Adenocarcinoma 83.25%.Mucinous carcinoma was the the second frequent histologic type which accounted for 6.4%.100% of lymphomas occurred in the caecum. Increasing burden of CRC is observed in the young. Frequency of Mucinous carcinoma increased with relatively young age predilection. Therefore, high index of clinical suspicion for CRC in the young recommended.en-USColorectal tumorsThesis
