Globus hystericus: a brief review.

Globus hystericus, a form of conversion disorder, is characterized by an uncomfortable sensation of a mass in the esophagus or airway. Evaluation proves no mass exists. Anxiety or psychological conflict is judged to be significantly related to the onset and progression of the sensation. The sensation may lead to difficulty swallowing or breathing and may become severe or life threatening. The disorder is poorly studied and understood. The differential diagnosis is vast. Management of the disorder is similar to that suggested for other conversion disorders. This article reviews the current literature about diagnosis, etiology, treatment, and prognosis of globus hystericus.
