INTRODUCTION: This case report aims to present a rare case of colon obstruction caused by a bezoar in a 15-year-old teenager. The significance of this case lies in the rarity of such obstructions and the necessity for early diagnosis and appropriate intervention to optimize patient outcomes. PRESENTATION OF CASE: A 15-year-old teenager presented with colicky abdominal pain, abdominal distension, nausea, vomiting, and rectal bleeding for three days. Initial investigations yielded normal results, but a digital rectal examination and abdominal X-ray suggested colon obstruction. The patient underwent surgical consultation and emergent laparotomy, during which a bezoar was identified and successfully removed endoscopically. Colonoscopy revealed that the bezoar was composed of shelled sunflower seeds, which correlated with the patient's dietary history. DISCUSSION: This case highlights the rarity of bezoars causing colon obstruction. Early recognition and appropriate intervention are crucial for optimizing patient outcomes and preventing complications associated with colon obstruction. CONCLUSION: This report highlights the importance of considering bezoars as a differential diagnosis in patients with colon obstruction. Early identification and treatment can prevent serious complications and improve clinical outcomes.
