Metastatic Primary Adenocarcinoma of Colon: A Case Report of 15-Year-Old Boy

Colorectal carcinomas are rare disease in the pediatric population, especially without known risk factors. The present article reports the case of a 15 year old boy with sporadic colon carcinoma who presented with acute intestinal obstruction symptoms during a soccer match. An annular colonic mass proximal to the hepatic flexure causing mechanical obstruction was observed on abdominal enhanced magnetic resonance. The diagnosis was confirmed by emergency laparotomy which identified an infiltrative and stenosing colonic mass, with serosal involvement and hepatic metastasis. Histological examination of the mass revealed a moderately differentiated adenocarcinoma. The present study aimed to suggest that malignancies should be considered by pediatricians and pedi¬atric surgeons for differential diagnosis when patients present with intestinal obstruction symptoms such as unexplained persistent constipation, abdominal distension or bleeding per rectum, as early diagnosis and treatment decreases the mortality rate of patients.
