Synopsis

Pitted keratolysis (also known as keratoma plantare sulcatum and ringed keratolysis) is a noninflammatory bacterial infection of the plantar stratum corneum caused by any of the following bacteria: Kytococcus sedentarius (formerly Micrococcus sedentarius), Dermatophilus congolensis, or species of Corynebacterium or Actinomyces.

Affected areas are generally asymptomatic but can emit a foul odor due to the production of isovaleric acid by the bacterial metabolism of the leucine in sweat. Rarely, pruritus, pain, or burning may be present. Predisposing factors are excessive sweating and prolonged occlusion in a warm, humid environment. Although rare, the hands may be affected.
