Intermittent melena and refractory anemia due to jejunal cavernous lymphangioma: A case report.

Background: Lymphangiomas in the gastrointestinal tract are extremely rare in adults. As a benign lesion, small intestine lymphangiomas often remain asymptomatic and pose challenges for definitive diagnosis. However, lymphangiomas can give rise to complications such as abdominal pain, bleeding, volvulus, and intussusception.
