[An unusual presentation of superior vena cava syndrome].

Superior vena cava syndrome (SVCS) is a clinical picture resulting from the obstruction of superior vena cava. SVCS usually causes symptoms and signs related to the head, the neck, the upper extremities and the upper thorax. We report a case of unusual clinical presentation of SVCS in a 25-year-old male patient who suffered from lymphoblastic lymphoma in childhood. Clinicians should be aware of abdominal wall presentations of SVCS especially in patients having undergone central venous catheterization, even years before. SVCS could be an emergency situation, requiring specific treatment or contraindicating surgical procedures.
