Cutaneous lesions and early presentation of disseminated blastomycosis: A case report

Blastomycosis is a fungal infection caused by Blastomyces dermatitidis, which is hyperendemic to areas of Northwestern Ontario, Canada. Delayed diagnosis is common due to the condition's nonspecific clinical presentation, often resembling malignancy or other dermatological and infectious diseases. We report the case of a 27-year-old otherwise healthy male with an early presentation of disseminated cutaneous blastomycosis. Early recognition of cutaneous blastomycosis can significantly reduce morbidity, mortality, and the overall treatment burden by facilitating timely antifungal therapy. This case shares valuable early clinical presentation and photographs for clinical reference, aiding in earlier disease recognition.
