B38.3
Cutaneous coccidioidomycosis
Clinical Classification Guidelines
Medical Intelligence & Overview
Cutaneous coccidioidomycosis is a skin infection caused by the fungus Coccidioides, which is typically found in certain desert regions. This condition represents a form of coccidioidomycosis that affects the skin, often developing from a primary infection or as a complication of a systemic infection. Recognized by its distinctive skin lesions, this condition requires proper medical evaluation and management to prevent complications.
Causes & Symptoms
Clinical Causes: Inhalation of spores from the Coccidioides fungus commonly found in soil of arid regions like the southwestern United States, parts of Mexico, Central and South America. Dissemination of the fungus from a primary lung infection to the skin. Less commonly, direct inoculation of the fungus into the skin through trauma or skin injury.
Key Symptoms: Localized skin lesions which may appear as: - Papules or nodules - Ulcers with raised borders - Erythematous (red) plaques - Scaly patches Lesions may be itchy or painless. Possible presence of abscesses or persistent ulcers. Lesions can vary in size and number, often appearing on the face or extremities.
Diagnostic & Treatment
Diagnosis Path: Skin biopsy to examine tissue samples microscopically for fungal elements. Fungal cultures from skin lesions to identify Coccidioides species. Serological tests measuring antibodies against Coccidioides. Molecular methods like PCR for detecting fungal DNA. Imaging studies, such as chest X-ray, may be performed to evaluate for systemic involvement.
Treatment Protocols: Oral antifungal drugs, such as fluconazole or itraconazole, are commonly used for skin infections. In some cases, topical antifungal agents may be applied for localized lesions. Severe or disseminated cases may require hospitalization and intravenous antifungal therapy. Duration of treatment can range from several months to over a year, depending on response. Surgical intervention may be considered for excising persistent or non-healing lesions.
