Abstract

We report an unusual case of localized cutaneous nodular chromoblastomycosis caused by Diaporthe phaseolorum in a diabetic patient with previous kidney transplantation. Clinical presentation showing a group of multiple cutaneous brownish nodules located on unilateral leg was initially suspicious of subcutaneous phaeohyphomycosis. Diagnosis was confirmed by histological evaluation, mycological culture and molecular identification of causative organism. This was the first case presentation of chromoblastomycosis caused by Diaporthe phaseolorum. We encourage that the combination of clinical suspicion, skin biopsy, tissue culture and molecular diagnosis are important and remain the mainstay for making a diagnosis of the atypical cutaneous fungal infection especially from the uncommon causative fungi.
