Abstract
Background: Dermoscopy is a non-invasive tool widely used to improve the diagnostic accuracy of general dermatological conditions. Objective: To determine the dermoscopic features and their diagnostic value in distinguishing common inflammatory and infectious dermatoses. Materials and Methods: A cross-sectional study was conducted on patients clinically diagnosed with common inflammatory or infectious skin diseases. Baseline characteristics and clinical and dermoscopic findings were recorded. Dermoscopic variables were analyzed using a correlation matrix. A skin biopsy was performed for each patient for a definitive diagnosis. Results: Of 102 patients, 43 with dermatitis, 30 with psoriasis, 14 with lichen planus (LP), 5 with pityriasis rosea (PR), and 10 with others were included. Dull red background, patchy vessels, and scales showed significant positive correlations with dermatitis (r = 0.401, 0.488, and 0.327, respectively; p < 0.01), whereas bright red background, glomerular vessels, regular vascular distribution, and diffuse scales revealed significant positive correlations with psoriasis (r = 0.412, 0.266, 0.798, and 0.401, respectively; p < 0.01). For LP, whitish reticulate structures, purplish background, and dotted vessels mixed with linear vessels in the peripheral distribution were significantly positively correlated (r = 0.831, 0.771, 0.224, and 0.558, respectively; p < 0.05). Yellowish background and peripheral scales were predictive of PR diagnosis (r = 0.254 and 0.583, respectively; p < 0.01). Conclusion: Dermoscopy can be used as an adjunctive tool to differentiate conditions among common inflammatory and infectious dermatoses in order to minimize unnecessary invasive diagnostic procedures.
