Original Paper



Chromoblastomycosis is a chronic fungal infection of the skin and subcutaneous tissues caused by different melanized fungi. The disease occurs worldwide, particularly in tropical and subtropical regions but not reported in Vietnam.

Case Summary

A 47-year-old women was admitted to hospital 103, Hanoi, Vietnam, with a 10-year lasting lesion on backside of her right shank. Diagnosis of chromoblastomycosis was made after discovery of a muriform cell in histopathological examination. A black, slow-growth fungus was isolated and identified as Fonsecaea pedrosoi after molecular analysis. After 1-month treatment with itraconazole, the lesion has significant improvement.


This is the first case of chromoblastomycosis caused by Fonsecaea pedrosoi reported in Vietnam.
