Medical Care

After tinea nigra is diagnosed on the basis of the findings from the patient's history, physical examination, and appropriate laboratory test, a topical medication designed to eradicate the fungal infection should be applied to the respective area. Topical application of antifungal agents usually resolves tinea nigra within 2-4 weeks. Topical ketoconazole cream may be a good choice, [16, 30]  as well other antifungals. [31, 32, 33] Prolonged therapy may be necessary to prevent relapse. Repeated vigorous scrubbing or topical application of keratolytic agents can reduce pigmentation. [25]

Spontaneous healing has been described but is rare. [34]


Surgical Care

To aid the effectiveness of the topical medication in eradicating the dermatomycosis, the affected skin area should be scraped with a No. 15 scalpel blade prior to the initial application of the medicine.



Because infection is believed to occur after inoculation subsequent to trauma, patients should avoid potentially contaminated sources, such as soil, sewage, compost, and decaying wood.
