Cystic Chromoblastomycosis: An Unusual Presentation and Diagnostic Challenge.

Chromoblastomycosis (CBM), also known as chromomycosis, is a rare, granulomatous fungal infection caused primarily by pigmented fungi. It typically affects the skin and subcutaneous tissue and is usually acquired through traumatic implantation of fungal spores from contaminated soil, wood, or vegetation. The most common manifestations are verrucous or nodular lesions. Cystic forms are rare and can mimic other dermatologic conditions, leading to diagnostic challenges. We report a case of CBM in a 43-year-old male presenting with an unusual cystic lesion.
