Formic acid inhalation injury: a case report.

We report a case in which a patient sustained an inhalation injury as a result of aerosolized formic acid. The patient sustained a partial-thickness burn to the face from a chemical spray; however, as a result of aerosolization, he also inhaled formic acid. This resulted in a reversible pulmonary chemical injury. Inhalation of formic acid results in a reactive airway dysfunction syndrome--a common response to inhalation of an occupational irritant.
