Overview

Trichomycosis axillaris is a superficial bacterial colonization of the hair shafts in sweat gland–bearing areas, such as the armpits and the pubic area. It is a trivial disease of worldwide occurrence that is believed to be caused by the genus Corynebacteria (mostly Corynebacterium tenuis).

Presentation

It is characterised by yellow, black or red granular nodules or concretions that stick to the hair shaft. Usually the condition is symptomless and all that is noticed are sweaty, smelly armpits.

Treatment

Daily cleansing with soap and water and application of benzoyl peroxide generally cures the infection. Regular use of antiperspirants aids in prevention. Topical erythromycin is occasionally required to eliminate the infection.
