Ganser syndrome: review and case report.

The nosological conception of Ganser syndrome (GS) has evolved as the hysterical etiopathogenesis has been examined against psychosis, malingering, factitious disorders and/or organic lesions. Few articles and little scientific research and theory are available supporting the complicated diagnosis of GS. The similarities and differences between GS and factitious disorders and malingering are examined in depth here. More publications are needed on GS to clarify its nature and investigate its treatment and uncertain prognosis.
