Pediatric primary cutaneous blastomycosis clinically responsive to itraconazole.

Primary cutaneous blastomycosis is a rare infection, especially among children. We present the case of a 16-year-old immunocompetent adolescent boy with primary cutaneous blastomycosis arising after falling into a flowerbed in a region where the fungus Blastomyces dermatitidis is hyperendemic. Following treatment with itraconazole 200 mg 3 times daily for 3 days, followed by 200 mg 2 times daily for 6 months, the lesion healed with only residual dyschromia.
