Munchhausen syndrome results from a psychiatric disorder in which patients attempt to demonstrate signs and symptoms of serious organic diseases. In a review of the literature, we found 23 cases of Munchhausen syndrome accompanied by factitious hemoptysis, 2 presenting the same mechanism described herein. We report the case of a 23-year-old male with a recent history of multiple hospital admissions for investigation of bloody sputum, although no conclusive diagnosis had been made. Upon insistent questioning the patient admitted to aspirating his own blood with a syringe, holding it in his mouth and eliminating it in order to simulate hemoptysis. Munchhausen syndrome should be considered in patients presenting hemoptysis of obscure etiology.
