Pitted keratolysis: a common infection of active feet.

Pitted keratolysis usually presents no diagnostic difficulties because of its distinctive clinical appearance and odor. Participating in a sport that makes the feet hot and sweaty often contributes to this dermatologic condition. Sometimes simple measures such as proper foot drying and ventilating procedures are enough to clear the infection. The next line of treatment involves the use of topical agents such as erythromycin 2% solution.
