Pitted keratolysis.

Pitted keratolysis (PK) is a common superficial bacterial skin infection confined to the stratum corneum. It is clinically characterized by multifocal, discrete, pits or crater-like punched-out lesions, commonly over the pressure-bearing aspects of the foot. It is asymptomatic and associated with malodor. The surface is often moist and macerated. The diagnosis of PK is often clinical and unnecessary diagnostic procedures are not warranted. Lifestyle modifications form the cornerstone of the management of PK. It responds well to topical antimicrobials.
