Lymphangioma of the duodenum. (Diagnosis by endoscopic resection).

Submucosal lymphangiomas of the gastrointestinal tract are extremely rare entities. A case of a lymphangioma of the duodenum in a 66-year-old woman is reported. Diagnosis was made by endoscopy and tumor excision with a diathermy snare. The patient complained of crampy upper abdominal pain which only partially was referable to an gastric ulcer and stopped after polypectomy. Endoscopically, compressibility of the tumor is a characteristic sign. Roentgenographically, it may be easily overlooked.
