Pulmonary edema following skin absorption of organophosphate insecticide.

We report a case of acute pulmonary edema following exposure to organophosphate insectocide. Hypoxia, respiratory failure, and parasympathetic discharge are implicated in the pathogenesis and are related to the anticholinesterase activity of the toxicant. Rapid onset of acute pulmonary edema without cardiomegaly followed by prompt clearing are the radiographic features.
