[Hemoptysis: an uncommun case].

Defined as an expectoration of blood from the subglottic airways, the hemoptysis is a symptom that suggests a variety of pathologies that can be more or less benign and even fatal, a life threatening for the person who suffers it. Between the most common causes we have bronchitis, bronchiectasis and bronchopulmonary neoplasia. Less frequent causes are: Goodpasture's syndrome, Wegener's granulomatosis, systemic lupus erythematosus, between others. The authors present a case of hemoptysis in a patient who suffered sudden aggravation of his general state with the need for intensive care.
