[An unusual cause of hemoptysis: a leech].

We report an exceptional case of hemoptysis observed in a 38-year-old woman with an uneventful past history. Bronchial fibroscopy demonstrated the presence of a leech attached to the laryngeal orifice. This condition is common in endemic areas but is underdiagnosed. The association of hemoptysis, voice alterations, and difficult respiration are suggestive signs. Extraction should be achieved rapidly to avoid death due to acute respiratory failure.
