[Duodenal lymphangitis carcinomatosa: a rare endoscopic finding].

We herein report a case of a 67-year-old male with a rare endoscopic finding in the duodenum. Upon gastroscopic inspection, the duodenal mucosa showed lymphectasia. The histology of these lesions surprisingly described lymphangitis carcinomatosa of the duodenum, which has only been described in a few cases so far. As the prognosis of patients with this condition is poor, endoscopists should have a high degree of awareness of this finding.
