The incidence of erythrasma is reported to be around 4%. This infection is observed all over the world; the widespread form is found more frequently in the subtropical and tropical areas than in other parts of the world. [4] .The infection occurs less often in children and tends to be more prevalent among college students in dormitories, soldiers in barracks, and senior adults in nursing facilities. Erythrasma incidence may increase with age.

In a study conducted in Turkey, the rate of erythrasma was found to be 46.7% among 122 patients with interdigital foot lesions. [5]

In a cross-sectional study of 80 patients with confirmed superficial cutaneous intertriginous infections in Tehran, Iran, erythrasma was the second most common infection after dermatophytosis [6] ; it accounted for 35% of the cases. The toe-web spaces were the most common sites, followed by the groin and axillary vaults.

The occurrence of erythrasma on the palm of one patient has been reported and appears to be unique and rare. [7]
