Trichomycosis (trichobacteriosis) is an asymptomatic superficial bacterial colonization of the hair shaft that is clinically characterized by pale yellowish, reddish or blackish sticky, cylindrical concretions surrounding the hair shaft in the axillary or pubic region. As far as we know, the first and only case of trichomycosis capitis was reported in a 8-year-old boy in 2011. We encountered no cases of trichomycosis in infancy in the literature. The current case displays an atypical presentation of trichobacteriosis involving head hair in a 10-month-old male infant.
