Late relapse of pulmonary blastomycosis after adequate treatment with amphotericin B. Case report

A 53-year-old man experienced relapse of pulmonary blastomycosis 9 years after having been treated successfully with amphotericin B and responded satisfactorily to retreatment. Relapse of blastomycosis after adequate treatment with amphotericin B is apparently uncommon. However, published reports include relatively few patients who have had long-term follow-up.
