Chromoblastomycosis is a chronic cutaneous fungal infection caused by dematiaceous fungi. It is a therapeutic challenge because of the lack of specific treatments. We describe a refractory case of chromoblastomycosis in which the lesion did not respond to initial treatment, but then use of topical imiquimod cured the lesion successfully.
