Duodenal hemangiolymphangioma presenting as chronic anemia: a case report

Background Lymphangiomas are a heterogeneous group of congenital vascular malformations characterized by cystic dilation of lymphatic vessels. They can occur at any age, but they are more common during childhood and in cutaneous localizations. Hemangiomas and vascular malformations of the gastrointestinal tract are very uncommon. Most are asymptomatic and diagnosis is often made as an incidental finding during endoscopy. On rare occasions the initial manifestation can be chronic anemia due to low grade gastrointestinal bleeding. They constitute an unusual manifestation and there is a low incidence of this type of tumor.
