Summary

A 45-year-old man presented to the emergency ward with features of intestinal obstruction of 2 days duration. On admission, there was abdominal distension and multiple sessile polyps found on digital rectal examination. In addition, a soft tissue swelling near the elbow and a bony swelling over scalp were noted. Abdominal radiography revealed gaseous distension of the small and large bowel, and ultrasound revealed diffuse, gas-filled bowel with sluggish peristalsis. The obstruction failed to resolve with conservative measures and at emergency laparotomy an irregular hard recto-sigmoid junction mass was identified. A defunctioning transverse loop colostomy was undertaken and the abdomen closed. During recovery, a colonoscopy was performed and a malignant appearing lesion was identified 15 cm proximal to the anal verge. Further per-stomal colonoscopy revealed multiple sessile polyps from the ileo-caecal valve to the descending colon. The cutaneous and abdominal findings were consistent with a rare acute presentation of Gardner's syndrome.
