Itraconazole pulse therapy in chromoblastomycosis.
Although daily itraconazole has been used effectively in chromoblastomycosis, there is no record of pulse therapy for chromoblastomycosis. A 68-year-old woman with a history of slowly enlarging scaly plaque involving the left shoulder and lateral chest, presented to the dermatology clinic at General Hospital, Kalutara, Sri Lanka. Clinically chromoblastomycosis was suspected. Direct KOH smears showed sclerotic bodies and histology showed granulomata with characteristic brown spores. Itraconazole (Sporanox) 200 mg. b.i.d. orally was given for a week followed by 3 drug free weeks. This cycle was repeated for 6 months (i.e. 7 pulses). Clinical improvement was visible by 2 months. Scrapings and biopsy repeated 5 months after the commencement of treatment were negative for chromoblastomycosis. The lesion had clinically healed by 5 months. Examination 8 months after cessation of treatment did not show any recurrence. Itraconazole pulse therapy is cheaper than daily treatment but effective in chromoblastomycosis. The optimal dosage and end point of treatment need to be ascertained after a larger study.
