Bilateral tinea nigra in a temperate climate.
Tinea nigra is a superficial mycosis associated with a dematiaceous fungus called Phaeoannellomyces werneckii. It is clinically characterized by asymptomatic non-scaly brown and black macules, the most common localization is the palmar region. Only one bilateral case occurring on the plantar skin and four palmar bilateral cases have been reported. We report the case of a 5-year-old boy presenting two hyperpigmented lesions with an irregular contour in both palmar regions, which appeared three months prior to presentation. Topical treatment with ketoconazole was effective.
