| description | Introduction: Trichoscopy is a well-acclaimed diagnostic tool
for numerous dermatoses. Scalp disorders contribute to a
significant percentage of daily visits to the outpatient dermatology
department, and a multitude of trichoscopic signs have been
documented in the literature. The consistency and repeatability
of these signs add weight to their diagnostic value.
Aim: To determine the various trichoscopic patterns observed in
classical cases of scalp dermatoses and to differentiate between
different scalp disorders.
Materials and Methods: The present observational crosssectional study included 100 newly diagnosed cases of scalp
dermatoses attending the Dermatology Outpatient Department
at Sree Balaji Medical College and Hospital, Chennai, India.
The study was conducted over a period of six months (180
days) from December 2021 to May 2022. After obtaining a
thorough history and conducting clinical examinations, patients
underwent trichoscopy. Photographs were taken, and the data
obtained were systematically tabulated. The scalp disorders
studied included Androgenetic Alopecia (AGA), Alopecia
Areata (AA), Telogen Effluvium, Tinea Capitis, Trichotillomania
(TTM), Seborrhoeic Dermatitis, Scalp Psoriasis, Discoid Lupus
Erythematosus (DLE), Lichen Plano-Pilaris (LPP), and scalp
verruca. All data were entered into Microsoft excel and analysed
using Statistical Package for Social Sciences software.
Results: Trichoscopic findings from the 100 cases were
categorised and tabulated according to pattern and condition
for better understanding and comparison. Trichoscopic patterns
observed were categorised as dots, vessels, shaft patterns,
and changes in the inter and perifollicular areas. Out of the 100
patients, 67 presented primarily with alopecia, of which 56 patients
(83.5%) had non scarring alopecia and 11 patients (16.4%) had
scarring alopecia. The highest number of cases was observed
in alopecia areata (n=20), where exclamation mark hairs were
seen in all individuals, followed by coudability sign, yellow dots,
and black dots. Among the androgenetic alopecia cases (n=18),
anisotrichosis, pearly white dots, yellow dots, and an increased
vellus-to-terminal hair ratio were observed in 100% of cases.
Conclusion: While certain signs/findings are specific, most
trichoscopic patterns overlap in various skin conditions. Therefore,
dermatologists should be aware of the patterns observed in
trichoscopy and the need to stay updated with the latest findings. |
