Erythrasma:
Information for adults

Erythrasma looks like a patch of pink to red, scaly skin. The border of erythrasma is well-defined, meaning there is a sharp border between the affected patch and the surrounding normal skin. Over time, the pink or red color fades to tan or brown.

Erythrasma is typically located in moist body folds such as:

• Under the arms (axillae)
• In the groin and inner thighs
• Between the toes, especially between the 4_^th and 5_^th toes

Less commonly, erythrasma can be found in the buttock crevice or in the folds underneath the breasts. In certain individuals, especially in those with diabetes, the infection can become widespread and can involve the trunk, arms, and legs.

Erythrasma usually causes no symptoms, but some people report mild itching or burning, especially in the groin area.
