Abstract

A 59-year-old Japanese man presented with a slightly elevated, pruritic, erythematous plaque on his left buttock measuring 5 × 5 cm in diameter. The man had a history of chromomycosis, dating 6 years prior to the current consultation, for which he had been treated with oral terbinafine. Diagnosis of a recurrence of chromomycosis of the skin due to infection by Foncecaea pedrosoi was made after careful analysis of the clinical features, skin biopsy, KOH mounts, and fungal culture results. We administered topical heat thereapy followed by treatment with CO2 laser to eradicate the unresponsive remnants of the lesion. The operative site re-epithelized within 10 weeks, and 1 year after the treatment there was no evidence of recurrence.

 For a recalcitrant case of chromomycosis, as in this case, the use of CO2 laser combined with topical heat therapy may be a new therapeutic modality.
