Pulmonary hemorrhage due to inhalation of vapor containing pyromellitic dianhydride.
Pulmonary hemorrhage due to inhalation of fumes or powders containing trimellitic anhydride (TMA) is well known. We report pulmonary hemorrhage in a young man exposed to epoxy resin vapor containing pyromellitic dianhydride (PMDA). Serum IgG antibodies to PMDA could be detected. We conclude that the pulmonary hemorrhage was mediated by a reaction to PMDA in analogy to the TMA-induced disease. We suggest that exposure to any acid anhydride should be considered a possible cause of pulmonary hemorrhage since these compounds share structural and functional similarities.
