Pitted keratolysis in Child
Alerts and Notices
Synopsis

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.
