[Münchhausen's syndrome--a diagnosis to remember].

We hereby report a case of self mutilation against the right upper extremity in a 26-year-old male. The condition started after a minor trauma. After a few days the diagnosis compartment syndrome was suspected and a fasciectomy of the forearm was performed. The patient subsequently claimed that he had experienced further symptoms. Despite countless investigations, it was not possible to identify the course of the patient's symptoms. It has become clear that the patient suffers from >>Münchhausen's syndrome<<.
