Local antibiotic therapy (fusidic acid) was ineffective in 4 cases. Suspicion of mycobacterial infection prompted us to initiate a 1-month regimen of oral minocycline hydrochloride, 100 mg, twice daily, for 6 patients. Among these 6 patients, 2 patients experienced minocycline-induced vertigo that prompted us to replace minocycline treatment with clarithromycin stearate therapy, 250 mg, twice daily, for 1 month. One patient was immediately given clarithromycin. Finally, 1 patient, treated for 2 months with local antibiotics only (bacitracin and neomycin sulfate), was lost to follow-up. In all 7 cases treated by oral antibiotic therapy, lesions improved within the first month. None of the patients returned for consultation, presumably because complete healing occurred. Five patients were contacted by telephone in October 2007 and reported that no relapse had occurred.
