Unusual Cause of Gastrointestinal Bleeding in a Patient with Turner Syndrome

Turner syndrome is an exclusively female genetic disease caused by complete or partial absence of the second X chromosome. It is classically characterized by congenital lymphedema, short stature, and gonadal dysgenesis. In addition, the syndrome is associated with several other abnormalities. One of them is gastrointestinal bleeding, which is frequently associated with inflammatory bowel disease, but it can also be caused by vascular lesions such as hemangioma, vascular ectasia, and telangiectasia. We report the case of a patient with Turner syndrome with an episode of gastrointestinal bleeding, outlining our pathway for the investigation and treatment of this condition.
