Chapped fissured feet

 

Chapped fissured feet (sweaty sock dermatitis, peridigital dermatitis, juvenile plantar dermatosis) are seen initially with scaling, erythema, fissuring, and loss of the epidermal ridge pattern. The tendency to severe chapping declines with age and is gone around the age of puberty. The mean age of onset is 7.3 years; the mean age of remission is 14.3 years. Onset is in early fall when the weather becomes cold and heavy socks and impermeable shoes or boots are worn. An artificial intertrigo is created when moist socks are kept in contact with the soles. The skin in pressure areas, toes, and metatarsal regions becomes dry, brittle, and scaly, and then fissured . The chapping extends onto the sides of the toes. Eventually, the entire sole may be involved; sometimes the hands are also affected .
