findings of gastrointestinal tract tumors in children and adolescents. a–c A 16-year-old girl presented with complaints of fatigue, abdominal pain and diarrhea for the last 6 months. CT examination was performed when a suspicious mass was seen in the liver on US. a–c Contrast-enhanced axial and coronal reformatted CT images show diffuse increased wall thickening at the splenic flexure and transverse colon (arrows). Note the subcapsular metastatic lesion adjacent to the right liver lobe (arrow). Ca-125 level was found to be high (234 U/mL, normal range 0–35 U/mL). The patient was operated and the histopathological diagnosis was colon mucinous adenocarcinoma

Mucinous carcinoma of the colon is a distinct form of colorectal cancer found in 10-15% of patients with colorectal cancer. It differs from conventional adenocarcinoma in terms of clinical and histopathological characteristics.

For the cecal appendix, please refer to the article on mucinous adenocarcinoma of the appendix.

Epidemiology

There may be a slightly greater female predilection.

Clinical presentation

Patients may present with a more advanced stage of the disease.

Pathology

It is characterized by abundant mucous secretion comprising at least 50% of the tumor volume.

Radiographic features

CT

Mucinous carcinoma may show severe and more eccentric bowel-wall thickening.

Other described features include :

  • more frequent presence of intratumoral calcification
  • more common heterogeneous contrast enhancement
  • more areas with hypoattenuation
  • solid portion of mucinous carcinoma may show showed less enhancement than that of nonmucinous carcinoma
  • can produce cystic or calcified hepatic metastases
  • can cause widespread intraperitoneal metastases

Treatment and prognosis

It has long been associated with an inferior response to treatment compared with adenocarcinoma.

History and etymology

It was first described by the general surgeon Dr. Duncan Parham in 1923.
