Tinea nigra is a fungal infection that is mainly seen on the palms of the hands or soles of the feet causing a dark brown to black discoloration of the affected skin. The word tinea means a fungal infection and nigra means black.
Eczema is one such fungal infection but it can be dramatic and is easily identified. A better fit for small white patches on your hands is a mild fungal infection called tinea versicolor. This fungal infection is caused by Malassezia globosa and Malassezia furfur.
