Trichobacteriosis (trichomycosis) is an asymptomatic infection at the axillary hair level caused by a bacterium of Corynebacterium spp. The aim of this study is to identify the clinical, epidemiological, and microbiological characteristics of previously reported cases. A review was conducted including the cases of trichomycosis (trichobacteriosis) reported in the PubMed database up to June 2023. Twenty-nine articles were included, involving 365 patients in total. A higher incidence was observed in men, representing 94% of the cases, most of which were in the age range of 20-50 years. The most frequently affected clinical topography was the axillar (90% of the cases). Most of the patients presented change in hair texture and bromhidrosis, some other frequent clinical manifestations were hyperhidrosis, hair color change, and cromhidrosis; 6% of the patients were asymptomatic. The etiological agent most frequently identified was Corynebacterium spp., the flavescens variety being the most prevalent. The most common form of treatment was shaving and topical clindamycin. In conclusion, trichobacteriosis is an infection that most frequently affects men at the axillary level; it manifests clinically with few symptoms and usually has a good response to treatment.
