Commentary: Erythrasma Capitis and Hair Loss – An Underdiagnosed Entity?

Corynebacterium minutissimum, typically part of normal skin flora, is known to cause erythrasma in various body regions but is rarely reported on the scalp. There is only one case report involving two young women where this bacterium caused diffuse and patched hair loss on the scalp, suggesting the possibility of underdiagnosis. Oral antibiotics used for other infections and acne might reduce the risk of scalp erythrasma, potentially preventing this rare outcome.
