Among the numerous causes of prolonged fever of unknown origin, the factitious fevers are frequently considered last after much diagnostic and therapeutic effort. Five observations of factitious fever are presented including 2 cases of thermometer manipulation in men aged 45 and 80. The latter patient is the oldest in whom such a case has been reported. In the first case the prolonged fever led to exploratory laparotomy with splenectomy followed by antilymphoma chemotherapy before the thermometer manipulation was discovered. This patient had previously been treated successfully for stage Ib Hodgkin lymphoma. In the other case hospitalization had lasted several weeks, and much antibiotic and steroid treatment had been administered, before the manipulation was suspected. A third case of thermometer manipulation was observed in a 57-year-old woman who had been presenting with factitious symptoms for over 10 years. Two other cases of factitious fever due to self-induced infections have been observed in two young women aged 23 and 27, both in paramedical professions. These self-induced infections led to polymicrobial bacteremia, exploratory laparotomy and hemicolectomy in one case, and to probable bacterial meningitis in the other. Certain aspects of these cases agree well with the diagnostic criteria of factitious fever described in the literature. We feel it is important to recognize this cause of febrile states, even if there is an apparent etiology, in order to avoid much vain investigation and prolonged hospitalization.
