Abstract
The clinical courses of 14 children with acute pulmonary blastomycosis were studied. All the patients had a remarkably similar illness limited to the lungs with fever, malaise, and respiratory symptoms (cough, sputum production, chest pain, and vomiting). Despite eventual recovery with treatment in all instances, 13 of the 14 children persisted in having abnormal roentgenograms. Three children have demonstrated persistent mild obstructive airway disease for two to 12 months after completion of therapy. These data suggest that the initial illness following childhood infections with Blastomyces dematitidis is usually an acute pulmonary disease without systemic dissemination. Evidence of residual lung abnormalities conflicts with the recent concept of this being a benign, self-limited illness. Our findings suggest the importance of long-term follow-up as well as a need for more complete understanding of the full clinical spectrum and prognosis of acute pulmonary blastomycosis.
