Trichomycosis or palmelin trichobacteriosis it is an infrequent reason for consultation in dermatology services, important to recognize and differentiate it from other pathologies since it can be difficult to diagnose.

Trichomycosis or trichobacteriosis is a rare, asymptomatic superficial infectious condition, caused in most cases by Corynebacterium flavescens (also called Corynebacterium tenuis), belonging to the Corynebacteriaceae family, which are gram-positive, pleomorphic, immobile, non-encapsulated bacteria, aerobic or facultative anaerobic. It affects hairs in the axillary region, pubic, scrotal and intergluteal area; It is due to the increase in the bacterial population of the normal microbiota, attached to the hair cuticle. This affectation is typical of humid climates, predominantly affecting young adults, males, athletes and homosexuals in an environment of poverty and overcrowding.

The objective of this article is to report a case of trichomycosis palmellina flava in the pubic region present in a young adult and to present the clinical characteristics of this relatively unrecognized condition.

Keywords : Corynebacterium flavescens; Corynebacterium tenuis; trichomycosis; hair shaft; microbiota.
