Dermoscopic findings of rosacea and demodicosis

Rosacea is a common chronic inflammatory disorder affecting the facial skin.Dermoscopy is a noninvasive procedure that is commonly used for the diagnosis of dermatological diseases. This article aims to determine the clinical and dermoscopic manifestations of the rosacea patients and the presence of the accompanying Demodex.The study evaluated 23 patients who were diagnosed with rosacea through clinical and dermoscopic findings. The patients were clinically and dermoscopically photographed and were classified according to the rosacea classification. The presence of Demodex was demonstrated both dermoscopically and through biopsy.There were a total of 23 participants (17 females and 6 males). The ages of the participants ranged between 28 and 75, with an average of 49. Among the 23 participants, 14 were erythematotelangiectatic, 7 were papulopustular, and 2 were rhinophyma. A total of 12 participants (4 males and 8 females) had ocular involvement. The most common dermoscopic finding was a linear vascular structure. A total of 15 patients (11 females and 4 males) had the demodicosis finding.The diagnosis of rosacea and demodicosis through dermoscopic findings is as reliable as a biopsy and it has the advantage of being noninvasive.
