Posalfilin is a drug containing podophyllin and salicylic acid that is used to treat the plantar wart.
Skin striae go around plantar warts; if the lesion is not a plantar wart, the striations continue across the top layer of the skin.
Evidence on the relation of barefoot physical education, whether in senior girls schools or elsewhere, to the spread of plantar warts is conflicting.
It is applied directly to the wart (especially plantar warts) and covered (for example: with tape).
Plantar warts are often similar to calluses or corns, but can be differentiated by close observation of skin striations.
