BACKGROUND: Many methods and medications had been tried for the treatment of chromoblastomycosis with unsatisfactory results. Recently, there were several reports showing a good response of chromoblastomycosis to itraconazole, but it took as long as 18-30 months for lesions to heal. METHODS: Itraconazole, 200 to 400 mg/day alone or in combination with monthly liquid nitrogen cryotherapy, was tried on 10 cases of chromoblastomycosis, caused by Fonsecaea pedrosoi in order to increase the potency of the drug and shorten the duration of treatment. RESULTS: The 10 cases included five newly diagnosed and five recalcitrant cases. Two patients were cured by 200 mg/day alone within 3 months. Seven patients required itraconazole, 400 mg/day, with combined cryotherapy to cure the lesions within 5 to 10 months. One case showed marked improvement but no cure. After the period of 1-year follow-up, only one case had a recurrent infection. CONCLUSIONS: Itraconazole was highly effective and may be useful in the treatment of chromoblastomycosis. A high dose is indicated in chronic fibrotic lesions in combination with liquid nitrogen cryotherapy, with higher efficacy and quicker healing than with medication alone.
