Pitted Keratolysis

Pitted Keratolysis is caused by Corynebacterium species, Actinomyces or Micrococcus. Pitted keratolysis is a descriptive title for a skin condition affecting the soles of the feet. Pitted keratolysis affects those who sweat profusely (hyperhidrosis) especially if they wear occlusive shoes or boots for long periods. It is caused by corynebacteria, and/or possibly the bacteria Dermatophilus congolensis.

Pitted Keratolysis is a common term for a group of the superficial skin infections, which involves keratin layer.  Plantar surfaces are usually affected. The typical features of Pitted Keratolysis are crater-like skin lesions and frequent maceration of skin related to hyperhidrosis.

Pitted keratolysis is usually easily diagnosed because of its distinctive clinical appearance and odor. Pitted keratolysis can be successfully treated with topical antibiotics such as fusidic acid cream, or with oral erythromycin.

Effective long-term treatment and prevention require removal of the warm, moist conditions that promote bacterial growth. Patients of Pitted keratolysis should wear socks made of either cotton or absorbent synthetic material and change them frequently, taking extra socks to work or school. Socks should also be changed after strenuous workouts. Do not share footwear or towels with others.
