Allergic contact dermatitis in patients with frontal fibrosing alopecia: An international multi‐center study

2020

Frontal fibrosing alopecia (FFA) mainly affects the anterior hairline and eyebrows and its etiology and associated factors remain obscure. The aim of this study was to evaluate the allergic contact dermatitis with patch test in patients with FFA. In this prospective study, 20 patients with FFA and 24 age and sex-matched healthy individuals were evaluated with patch testing. Diagnosis was made histologically, clinically and based on dermoscopic findings. Demographic data, age of onset, disease duration and FFA severity index are evaluated in all patients. Positive patch test reaction to one or more allergen was observed in 65% of patients while it was 37.5% in control group (P = .003). There…

Trichoscopy features of trichotillomania

2019

Trichotillomania is a form of traction alopecia resulting from repetitive and compulsive hair pulling and plucking. Trichotillomania and patchy alopecia areata may have similar clinical and dermoscopic features in some cases. On trichoscopic examination, the presence of black dots, coiled or hook hair, shafts of varying lengths with fraying or split ends (trichoptilosis), and an absence of exclamation mark hairs and yellow dots are suggestive of trichotillomania.

Differentiation of frontal fibrosing alopecia and Lichen planopilaris on trichoscopy: A comprehensive review.

2021

Trichoscopy in dermatology has opened up the new concept in overcoming the optical challenge faced clinically. It reveals the diagnostic details to the depth of superficial dermis, and thereby increasing the clinician's diagnostic accuracy and the level of confidence. The importance of trichoscopy in cicatricial alopecia is very evident in the current scenario for its precise diagnosis. The clinical picture in delineating lichen planopilaris (LPP) and frontal fibrosing alopecia (FFA) from each other and also from other close mimickers such as androgenetic alopecia, alopecia areata, female patterned hair loss, and other cicatricial alopecia is bewildered due to its varied presentation and co…
