It accounts for severe morbidity and poor prognosis owing to the low index of suspicion, delayed diagnosis, advanced stage at presentation and the aggressive tumor nature. Patients present with abdominal pain, vomiting, constipation, abdominal distension, rectal tenesmus, iron-deficiency anemia, change in bowel habit and weight loss. Rectal bleeding is an uncommon presentation in children. Bowel obstruction presents frequently in children compared to adults. In 90% of pediatric cases, colorectal carcinoma occurs sporadically. In 10%, predisposing conditions and syndromes are identified. We present a case study of a 12-year-old female with advanced colorectal cancer without a predisposing disease or syndrome, who received radiochemotherapy ten weeks prior to radical abdominopelvic surgery, followed by radio-chemotherapy postoperatively, with a positive outcome.en© 2017 National Cancer Institute, Cairo University.
