Tinea nigra affects the skin of the palm and/or sole with persistent slowly growing brown or black patches.
They are slightly scaly and do not itch or sting.
Tinea nigra is most common in tropical regions and often infects those with a tendency to excessive sweating (hyperhidrosis).
Tinea nigra is due to infection with a brown mould, Exophiala phaeoannellomyces. This mold usually inhabits soil.
