Abstract
The patient had a family history of colorectal cancer (father). He presented with a 10-day history of central abdominal pain, anorexia, and fever. A rapid loss of weight had occurred during this period. He was admitted to a hospital where colonoscopy revealed a polypoid mass at 30cm. This was diagnosed as a carcinoma and the patient was referred for operation. A further colonoscopy to the cecum was performed. The lesion was of an intense red color, lobulated, and with a smooth surface (Figure 22.1). Immediately proximal to it there was a less prominent but similar change in the mucosa. Diverticula were present in the sigmoid and descending colon. There was no other mucosal abnormality. Biopsy revealed mucosal inflammation. On rectal examination, there was a fixed left-sided pelvic mass. A preoperative diagnosis of diverticulitis was made.
