Erythrasma

Erythrasma is a chronic superficial infection of the intertriginous areas of the skin. The incriminated organism is Corynebacterium minutissimum, which usually is present as a normal human skin inhabitant. It is usually a benign condition. Axillae, submammary area, periumbilical region, and intergluteal fold are less commonly involved. It can last from months to years. Antibacterial and/or antifungal agents are used to eradicate C minutissimum and possible concomitant infection. Erythromycin is the drug of choice.
