Abstract
Duodenal lymphangitis carcinomatosa has been described sporadically. We report a new case of lymphangitis carcinomatosa of the duodenum. The gastroscopy showed a thickening of the duodenal folds which appears to be punctate, grainy, and reddish. This grainy appearance seems to be secondary to an expansion of neoplastic cells in the lymphatic vessels. On pathological study, lesions were characterized by a normal mucosa with presence in the upper part of the lamina propria of dilated lymphatic vessels containing aggregated neoplastic cells. These aspects were not found in the extralymphatic tissues of the lamina propria and the submucosa. The primitive tumor was endometrial. The patient died 70 days after diagnosis.
