Picture of Ringworm of the Hand

Ringworm infection can occur on the hands, especially on the palms and between the fingers. Often, just one hand is affected. Affected skin may have a rough, thickened (hyperkeratosis) appearance. Ringworm on the hands is called tinea manus. When ringworm occurs on the feet it is called tinea pedis. The two often occur at the same time.
