A bacterial infection usually seen in skin folds.
Causes, incidence, and risk factors
Erythrasma is a very specific chronic skin infection caused by Corynebacterium minutissimum. The typical appearance is a reddish-brown slightly scaly patch with sharp borders. The lesions occur in moist areas such as the groin, axilla and skin folds. The lesions may itch slightly or be asymptomatic. The incidence of erythrasma is higher in warm climates. It is most prevalent among heavier individuals and those with diabetes.
Treatment
Gently scrubbing the lesions with antibacterial soap may clear the disease. Topical erythromycin gel is very effective as well. In severe cases, your doctor may prescribe oral erythromycin.
Expectations (prognosis)
Complete recovery is expected following treatment.
Calling your health care provider
Call for an appointment with your health care provider if you or your child exhibit the scaly brown patches of erythrasma.
