Tinea Manuum
Tinea manuum, sometimes referred to as two feet–one hand syndrome, is similar to moccasin tinea pedis and often develops after the occurrence of tinea pedis or tinea unguium. The same fungal species that cause tinea pedis and tinea unguium also can result in tinea manuum. Typically, the hand used to scratch the foot with the rash is affected. The palm appears hyperkeratotic, with a fine white scale emphasizing the normal lines of the hand. The dorsal surface of the hand may exhibit a classic ringworm appearance. Tinea manuum may mimic eczema, contact dermatitis, palmar psoriasis, or dryness of the hand. Overall, tinea manuum occurs less frequently than either tinea pedis or tinea unguium. Preventive and treatment strategies, which are the same as for tinea pedis, are summarized in Table 1 and Table 2.
