# Cystic Chromoblastomycosis: An Unusual Presentation and Diagnostic Challenge

## TL;DR

This paper describes a rare case of a fungal skin infection that presented as a cyst, making diagnosis difficult.

## Contribution

The novelty lies in reporting an unusual cystic presentation of chromoblastomycosis, which is rarely seen.

## Key findings

- CBM typically presents as verrucous or nodular lesions, but cystic forms are uncommon.
- The case highlights diagnostic challenges due to the lesion's resemblance to other dermatologic conditions.

## Abstract

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.
