Tinea nigra in Child
After contamination from an infected source (eg, soil, sand, waste, or wood), the mycosis infects the stratum corneum, resulting in a dark macule or patch as the fungal hyphae produce melanin. The incubation period is typically 10-15 days.
The most frequently affected populations are children and adolescents (children are more prone to exposure to the fungus); however, persons of any age may be affected.
Immunocompromised Patient Considerations
The fungus involved in causing infections of tinea nigra can lead to serious infections in immunocompromised patients. There is a risk of disseminated disease from superficial cutaneous fungal infections noted in transplant patients.
