Gastric lavage for the diagnosis of pulmonary blastomycosis in pediatric patients.

A case of pulmonary blastomycosis in a pediatric patient diagnosed by gastric lavage is described. Use of gastric lavage averted the need for more invasive diagnostic techniques including bronchoscopy. Further study is required to define the sensitivity of gastric lavage for recovery of Blastomyces dermatitidis from pediatric patients with pulmonary blastomycosis.
