title: [Syncope in the debut of a mediastinal mass].
abstract: Pediatric syncope accounts for 3% of the consultations in emergency department. It is frequent in pediatrics, particularly in teenager girls between 15 and 19 years old, and up to a 25% of them have suffered from a syncopal episode. Most causes are benign, but the aim in its initial evaluation is ruling out those which mean any danger. Heart disease can lead to syncope in a 10-28% of cases. A detailed medical history and an exhaustive exploration are enough to rule out organic pathology in most situations. We present the case of a diffuse large B cell lymphoma located in the mediastinum diagnosed after repetitive syncopal episodes.
