History: Pitted Keratolysis is a bacterial infection of the plantar stratum corneum . The thick, weight-bearing portions of the soles become gradually covered with shallow asymptomatic discrete round pits, some of which become confluent, forming furrows. Men with very sweaty feet during hot, humid weather are most susceptible. No discomfort is produced, though the lesions are often malodorous. Clinical diagnosis is not difficult, based on its unique appearance. This patient suffered typical pitted keratolysis. The condition is so alleviated by topical erythromycin treatment.
