Pulmonary Alveolar Proteinosis and Tracheal Stenosis After Exposure to Fire and Fire Extinghuisher

Abstract

Pulmonary alveolar proteinosis (PAP) is a rare disease characterized by the accumulation of acellular surfactant lipids and proteins within the alveoli. Idiopathic PAP accounts for about 90% of all patients. Secondary PAP factors include insecticides, inorganic dusts such as silica, hematological malignancies, Human Immunodeficiency Virus infection, leflunomide, toxic gas inhalation, various industrial exposures to aluminum-and metal oxide-containing dusts and clinical conditions. Herein, we present a case of pulmonary alveolar proteinosis and tracheal stenosis secondary to exposure to fire and fire extinguisher.
