Pitted keratolysis is a skin disorder characterized by crater-like pitting that primarily affects the pressure-bearing aspects of the plantar surface of the feet. The manifestations are due to a superficial cutaneous bacterial infection.

Symptoms
  • Punched out pits in the stratum corneum
  • malodor
  • hyperhidrosis (excessive sweating) or sliminess
  • occasionally,soreness or itching associated with the pits
Main contributing factors 

Caused by a cutaneous infection with Kytococcus sedentarius, Dermatophilus congolensis, ,or species of Corynebacterium and Actinomyces. Under appropriate conditions (ie, prolonged occlusion, hyperhidrosis, increased skin surface pH), these bacteria proliferate and produce proteinases that destroy the stratum corneum, creating pits


Treatment for Pitted Keratolysis
  • Twice daily applications of topical antibiotics such as Erythromycin or Bactroban creams or gels.
  • Use antibacterial soap on your feet twice daily.
  • Limit use of occlusive footwear or alternate shoes to allow them to dry out
  • Change socks regularly
  • Anti-perspirant deodorant applied to feet may limit hyperhidrosis
What can you do?

A recurrence of pitted Keratolysis may be prevented by:

  • Wearing appropriate shoes and changing socks regularly
  • Using antibacterial soap
  • Using antiperspirant on feet
