What is tinea nigra?

Tinea nigra is a superficial fungal infection caused by the soil-dwelling fungus, Cladosporium werneckii. The primary symptom of tinea nigra is a single or multiple brown to black patches on the palms of the hands or soles of the feet. The patches are usually asymptomatic, but can be associated with mild itching or burning. Tinea nigra is most common in young children and adolescents, but can occur in any age group. The diagnosis is typically made based on clinical appearance, but can be confirmed by fungal culture or skin biopsy. Treatment is generally not necessary, as the condition is self-limited and will resolve without intervention within 4-12 weeks. However, topical antifungal therapy may be used for cosmetic purposes or if the lesions are symptomatic.
