Tinea pedis can be differentiated by clinical presentation and fungal examination. Tinea versicolor needs to be differentiated from a number of hand dermatoses, such as eczema, neurodermatitis, pemphigus, exfoliative keratolysis, chronic contact dermatitis, palmoplantar pustulosis, palmoplantar keratosis, and syphilitic rashes of the second stage. These rashes are negative for fungal microscopy and the rashes tend to be symmetrically distributed. Tinea versicolor should be distinguished from chronic eczema of the hand, tinea versicolor is usually unilateral, slow progress, clearer boundaries. Chronic eczema of the hands usually starts bilaterally at the same time, progresses faster, and the rash is hairy and the boundary is not clear. When suffering from tinea pedis, should consult a doctor in time, follow the doctor’s prescription medication.
