Case contributed by Dr Gaetano Marco Latagliata

Presentation

Anemia and abdominal pain in the left iliac fossa by a few months. Colonoscopy documents: stenotic adenocarcinoma of the left colon

Patient Data

Age: 69
Gender: Male
CT

The lesion in right iliac fossa appear homogeneous and cystic; it is well circumscribed with central areas of low attenuation, and the contents have Hounsfield values near those of water.

Stenotic colorectal cancer with segmental circumferential thickening near the splenic flexure in descending colon.

Pathology

Intra-operative and gross pathology photographs. 

Case Discussion

Left hemicolectomy and appendicectomy was performed and appendiceal mucocele and adenocarcinoma of left colon were proven.

Histology demonstrated non invasive low grade appendiceal mucinous neoplasm and adenocarcinoma of colon.

In patients with a mucocele, the risk of developing an adenocarcinoma of the colon is six times greater than that of the general population.
