Laryngeal Blastomycosis, an Unexpected Diagnosis: A Case Report.

Isolated laryngeal blastomycosis is an extremely rare entity with few cases described in the medical literature. Nonspecific and chronic presenting symptoms such as dysphonia, dyspnea, dysphagia, and/or cough are described, with isolated reports requiring urgent management related to respiratory distress. We present a case report of a 63-year-old immunocompetent female diagnosed with isolated laryngeal blastomycosis, document the treatment regimen and subsequent clinical course. In view of the rarity of this diagnosis, isolated laryngeal blastomycosis has the potential for clinical and pathologic misdiagnosis. Without an accurate diagnosis, blastomycosis remains untreated and the risk for airway disease progression increases.
