Erythrasma

Erythrasma is a common, chronic, superficial bacterial infection of the integumentary system primarily caused by *Corynebacterium minutissimum*, a normal cutaneous commensal The condition predominantly affects adults and manifests in warm, moist, intertriginous areas—most frequently the axillary, inguinal, inframammary, and interdigital spaces Pathophysiologically, the organism proliferates within the stratum corneum under humid or occlusive conditions, producing sharply demarcated, reddish-brow...

Erythrasma is a common, chronic, superficial bacterial infection of the integumentary system primarily caused by *Corynebacterium minutissimum*, a normal cutaneous commensal A hallmark clinical feature is the production of coproporphyrin III by the proliferating bacteria, which elicits a characteristic coral-red fluorescence under Wood’s lamp examination

The condition predominantly affects adults and manifests in warm, moist, intertriginous areas—most frequently the axillary, inguinal, inframammary, and interdigital spaces

The condition predominantly affects adults and manifests in warm, moist, intertriginous areas—most frequently the axillary, inguinal, inframammary, and interdigital spaces

Pathophysiologically, the organism proliferates within the stratum corneum under humid or occlusive conditions, producing sharply demarcated, reddish-brown to violaceous macules and plaques with fine scaling A hallmark clinical feature is the production of coproporphyrin III by the proliferating bacteria, which elicits a characteristic coral-red fluorescence under Wood’s lamp examination
