Dermoscopic Features of Follicular Dermatoses: A Cross-Sectional Study.
Article in Dermatology practical & conceptual, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionFollicular dermatoses are conditions characterized by localization around hair follicles, often presenting as small papular lesions. These dermatoses can be challenging to diagnose with the naked eye, making dermoscopy an important adjunctive diagnostic tool. However, the literature on the dermoscopic features of follicular dermatoses remains limited.
objectivesTo evaluate dermoscopic findings in follicular dermatoses.
methodsThis cross-sectional study was conducted from November 2022 to January 2024 at the dermatology department of a tertiary hospital. Patients were categorized into inflammatory and keratinization follicular dermatosis. A fully developed lesion was dermoscopically examined using a DermLite DL-5 dermoscope. The data were statistically analyzed.
resultsWe studied 147 patients. Most follicular dermatoses on dermoscopy showed classical findings such as keratotic plugs, perifollicular white halo, or brown halo. However, they also exhibited characteristic features unique to each dermatoses. Keratosis pilaris exhibited coiled hair (77.41%). Reactive perforating collagenosis presented a central yellowish plug (100%), whitish rim (100%), and peripheral erythematous halo (87.5%). Follicular LP showed reduced follicular ostia (45.45%) and blue-gray globules (40.90%), with newer findings like radial white stria and rosette. Follicular psoriasis displayed regular red dots (100%), while follicular eczema showed red globules (50%) and irregular red dots (16.7%). Acne keloidalis nuchae exhibited radial white streaks (62.5%), perifollicular white globules (50%), V-shaped hair (50%), and radial linear vessels (18.75%). Darier disease showed central hyperpigmented and white keratotic plugs, comedo-like openings, and interfollicular exaggerated pseudo-pigment areas.
conclusionOur study highlights that each follicular dermatosis presents specific dermoscopic patterns, supporting dermoscopy as a useful, noninvasive tool for differentiation that can complement histopathology.
