Juvenile plantar dermatosis (JPD)
Dermatitis/eczematous disorder of ball of foot in young children.
Theory – due to constant cycle of wet macerated feet drying. Wet athletic footwear that does not dry is a factor to be considered.
Begins as patchy, symmetrical, smooth red macule, usually around great toe with some fissuring. Progresses to shiny, cracked, dry, scaly and erythematous areas over toes and plantar forefoot (heel occasionally).
May be associated with atopic dermatitis (debatable)
Differential diagnosis – tinea pedis, contact dermatitis
Dry shoes; foot powders; absorbent insoles; emollients; cork insoles; natural fibre socks
Most case clear at puberty.
