Duodenal obstruction secondary to a metastasis from an adenocarcinoma of the cecum: a case report.

Metastatic tumors to the gastrointestinal tract are rare; the stomach and small bowel are the most common organs involved. Lung cancer, renal cell carcinoma, breast carcinoma, and malignant melanoma are the most common primary tumors metastatic to the duodenum. We report a metastasis to the duodenum from an adenocarcinoma of the cecum presenting as a duodenal obstruction 4.5 yr after the surgical resection of the primary tumor. The condition of the patient was temporarily controlled with the implantation of an endoduodenal metallic prosthesis as a palliative measure.
