Juvenile Forefoot Dermatitis
In
the summer months children who wear occlusive tennis shoe like footwear and who’s
feet sweat excessively, can present with this rash. It involves the forefoot
and sometimes the heels but spares the instep. It also spares the deep web
spaces between the toes. It is known as juvenile forefoot dermatitis. It was
first reported in the late sixties and may have been related to changing
fashions in footwear and socks. Histology shows an eczema and a blocking of
sweat glands. Sometimes the tips of the fingers can be fissured as well and
this is more common in atopic subjects which was the case in this boy. The
condition clears in late childhood or adolescence. He did have negative patch
testing to exclude a true footwear allergy. Treatment is cotton socks and
leather shoes plus a strong steroid ointment initially and good moisturising
thereafter. Tar such as 1% LPC in emulsifying ointment also works.
