Definition

Noun: A chronic fungal infection of the skin and subcutaneous tissues, typically characterized by the formation of slow-growing, itchy, warty (verrucous), or cauliflower-like nodules, usually on the lower limbs. It is caused by traumatic inoculation of certain dematiaceous (darkly pigmented) fungi.

Usage

This is a medical term used specifically in dermatology, infectious disease, and clinical microbiology contexts. It describes a distinct clinical condition.

Examples

• The patient presented with a long-standing, crusted lesion on the foot, which was diagnosed as chromoblastomycosis.
• Chromoblastomycosis is more common in tropical and subtropical regions.
• Treatment of chromoblastomycosis can be difficult and often requires a combination of antifungal therapy and physical methods like cryotherapy.

Advanced Usage

• The term is often used in differential diagnoses when a clinician encounters chronic, verrucous skin lesions in individuals from endemic areas.
• In histopathology, the finding of "sclerotic bodies" or "copper pennies" (thick-walled, brown, septate fungal cells) in tissue samples is diagnostic for chromoblastomycosis.

Variants and Related Words

• Chromomycosis: A synonym for chromoblastomycosis, though some sources use it to refer to a broader category of infections caused by dematiaceous fungi.
• Mycetoma: A different deep fungal infection that can cause similar localized swelling but is characterized by grain formation and sinus tract drainage, distinguishing it from chromoblastomycosis.

Synonyms

• Chromomycosis (in many clinical contexts)
