When intertrigo in the skin folds is complicated by Corynebacterium minutissimum superinfection, it requires targeted antibiotic management beyond standard skin-fold care. Wood lamp examination is key to confirming the diagnosis before selecting a treatment approach.
Intertrigo complicated by cutaneous erythrasma — a bacterial superinfection caused by Corynebacterium minutissimum. Skin lesions fluoresce coral-red on Wood lamp examination, distinguishing this from uncomplicated intertrigo and directing antibiotic therapy.
Erythromycin — available in both topical and oral formulations — is the primary treatment for cutaneous erythrasma complicating intertrigo. Oral therapy is generally considered more effective than topical application alone.
Additional antibiotic agents may also have a role. The complete regimen — including formulation selection, sequencing, and all evidence-based alternatives — is available in the full protocol.
Treatment goal: Resolution of the rash in the affected skin folds.
