Münchausen syndrome (MS) is now a well recognized and demonstrated entity. This syndrome is characterized by patients who seek hospitalization and present factitious but usually well-rehearsed histories and symptoms.
Five cases of MS, genuine by their ear-nose-throat-maxillofacial factitious signs, are presented. Two of the cases are related to the uncommon MS by proxy. In this subentity the parents fabricate pathological signs for their children. The psycho-dynamics and the clinical symptoms of our cases are described and the differential diagnoses of malingering, conversion disorders, and hypochondriasis are brought to attention.
