“…Greasy scales and comma hairs were the most common findings in TC, as noted by Chimarel et al [14,22]. Light microscopy (×40), as well as trichoscopy in "Trichomycosis axillaris," showed golden yellow nodules adherent to the axillary hair shafts in all patients, as was previously described by Almazan-Fernandez and Fernandez-Crehuet [23].…”

Background: Trichoscopy is a simple, non-invasive procedure practiced in the diagnosis of a multitude of scalp and hair disorders. Hair shaft abnormalities usually represent a diagnostic challenge to dermatologists. Objectives: To determine the practicality, versatility and value of using the hand-held dermoscope in assessment of hair shaft abnormalities and the diagnosis of different hair/scalp disorders. Methods: Eight hundred and seven patients of both sexes, aged from 1 to 76 years, with complaints pertaining to scalp and hair were the subjects of the study. All patients were examined by the hand-held dermoscope and 400 were additionally examined by the folliscope, digital dermoscope or their hairs mounted for light microscopy. Results: Based on trichoscopic findings, more than half the patients demonstrated thinned terminal hairs and predominance of single-haired scalp pilosebaceous units, 57%and 55.5% respectively. Over a quarter of the patients showed hair diameter heterogeneity, upright regrowing hairs and increased vellus hairs, 37%, 31% and 25% respectively. Other trichoscopic findings included scalp scaling (19%), hair weathering (12%), thinned wavy hairs (10.5%), brush-like hair fractures (9%), exclamation mark hairs (9%) and longitudinal cleavage (trichoptilosis) (8%). The clinical diagnostic spectrum was topped by the following diagnoses in order of frequency; female pattern hair loss, telogen effluvium, traction alopecia and trichotillomania. Trichodynia appeared significantly associated with numerous hair shaft abnormalities. Conclusion: Most hair shaft abnormalities can be reliably diagnosed with high accuracy using a handheld dermoscope in an office setting. Skillful knowledge of Dermoscopy is an important aid in diagnosis of hair and scalp disorders.

“…Paxton thought that he had detected spores like those found in favus or tinea favosa but was unable to find the mycelial structures [ 7 ]. Later, in 1927, Castellani observed that the flava variety was apparently caused by “a very thin fungus,” with a bacillary appearance, which he named Nocardia tenuis , but he was unable to cultivate it [ 9 , 10 ]. He attributed the rubra and nigra varieties to a symbiosis of this fungus with chromogenic cocci; a black pigment-producing cocci ( Mycrococcus nigricans ) in the nigra variety and red pigment-producing cocci in the rubra variety [ 11 , 12 ].…”

“…The family of these bacteria is usually part of the skin microbiota, representing around 50% [ 2 , 18 ]. Other agents involved are Corynebacterium propinquum or Serratia marcenscens [ 6 , 9 ]. Recently a case reported by Larrondo et al in 2017 caused by D. hominis was described, which is also part of the usual skin microbiota [ 19 ].…”

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.

Dermoscopy is becoming an indispensable tool in everyday practice, with an expanding range of applications. Trichoscopy is effective not only in establishing the diagnosis of scalp disorders but also in the follow-up of treatment. The MEDLINE database was searched using the terms "dermoscopy" and "trichoscopy" in combination with each of the following: "axilla," "pubic area," "beard," "eyebrows," "eyelashes," and "body hairs." We included case reports, case series, and review articles mentioning the previous terms. By providing an updated review from the literature, we aimed to emphasize the potential uses of trichoscopy in detecting diseases in hairy locations other than the scalp. Various inflammatory conditions, infections, and infestations are discussed.
