Abstract
Lymphangitis carcinomatosa (LC) is an entity characterised by a diffuse invasion of the lymphatic vessels by malignant cells [1]. It is generally localised within the lungs. Extrapulmonary localisation is rare. LC of the digestive tract is exceptional, and essentially affects the duodenum, and more rarely the stomach and the small intestine. LC of the colon has never been described. We are reporting two cases of LC of the digestive tract: one of the duodenum, the other of the colon.
