Chromoblastomycosis is a rare chronic fungal infection of skin and
subcutaneous tissue. It is primarily a disease of tropical and subtropical
regions and affects mainly the agricultural workers following trauma
with vegetable matter. Cutaneous Chromoblastomycosis may
clinically mimic cutaneous tuberculosis as both the condition usually
presents with hyper pigmented verrucous lesion of skin.
Here in we report a case of chronic cutaneous Chromoblastomycosis
in a middle aged woman from north eastern part of India, who
was initially misdiagnosed as Tuberculosis verrucosa cutis. In
histopathology characteristic brown colored spores of the fungus
(also known as copper pennies) were seen within dermal abscess.
The organism isolated from culture of the biopsy material was
Fonsecaea pedrosoi thus confirming our diagnosis of cutaneous
chromoblastomycosis. The patient responded well to oral Itraconazole.
The dermatologists and pathologists should be aware of this
condition especially when dealing with verrucous lesion of the skin.
The pathologists should search for fungal spores in cutaneous lesion
with pseudoepitheliomatous hyperplasia and dermal abscess.
