Chromoblastomycosis

Area of Science:

• Mycology
• Dermatology
• Infectious Diseases

Background:

• Chromoblastomycosis is a chronic subcutaneous fungal infection.
• It is caused by dematiaceous (pigmented) moulds found in the environment, commonly Fonsecaea pedrosoi and Cladophialophora carrionii.
• Infection occurs via traumatic inoculation, often from plant debris.

Purpose of the Study:

• To describe the etiologic agents, clinical presentation, diagnosis, and treatment of chromoblastomycosis.
• To highlight challenges in patient management and treatment outcomes.

Main Methods:

• Direct examination of skin scrapings.
• Histopathologic studies to identify muriform bodies.
• Microbiologic culture for etiologic agent determination.

Main Results:

• The infection presents as papules or nodules progressing to scaly plaques.
• Muriform bodies are characteristic findings in direct examination and histopathology.
• Microbiologic culture is essential for identifying the specific fungal agent.

Conclusions:

• Itraconazole combined with surgery is the primary treatment.
• Late presentation, financial constraints, and the disease affecting primary earners often lead to unsatisfactory outcomes.
• Accurate diagnosis and timely intervention are critical for effective chromoblastomycosis management.
