“…8 Moreover, abnormal Demodex mite proliferation in patients with other known skin or systemic diseases can cause secondary demodicosis, which is often mistaken for inflammatory dermatoses. [9][10][11] The diagnosis criteria should include a correlation between clinical skin lesions and abnormal Demodex mite proliferation, confirmed by complete clinical improvement and normalization of Demodex mite density with acaricidal agents. A dermoscopy can be used to detect Demodex tails and follicular openings of Demodex mites on suspicious skin lesions.…”

“…A dermoscopy can be used to detect Demodex tails and follicular openings of Demodex mites on suspicious skin lesions. 11,12 Demodex mite density is critical for diagnosing demodicosis. Standardized skin surface biopsy (SSSB) is commonly used to determine the density of Demodex mites per square centimeter, and a diagnosis of demodicosis is made when the density exceeds 5 mites /cm 2,8,13 A method known as "superficial needle scraping" (SNS) is used to assess the density of Demodex mites in papulopustular lesions.…”

An abnormal density of Demodex mites can trigger many skin disorders known as demodicosis. Clinical manifestations of demodicosis may resemble other skin diseases and can coexist with other skin disorders, resulting in underdiagnosis and a more challenging diagnosis. Here, we report three cases of demodicosis in acne vulgaris patients. These case series have discussed their clinical features along with optimal strategies for diagnosis and treatment.

“…There is growing evidence on the potential role of dermoscopy in diagnosis of demodicosis [1][2][3][4][5][6]. Dermoscopy proved to be an effective diagnostic tool and to correlate with standard skin surface biopsy results in cases of facial, scalp and truncal disease [4,7,8].…”

Introduction: There is growing evidence of the potential uses of dermoscopy in diagnostics of demodicosis. No previous studies have analyzed dermoscopic features in patients with ocular demodicosis. Objectives: To evaluate the potential usefulness of videodermoscopy in diagnostics of ocular demodicosis. Methods: It was a single-center prospective observational study in which results of videodermoscopic examination of the eyelids were compared to the results of classic microscopic examination in patients with suspected ocular demodicosis and healthy volunteers. Results: Study group included 16 women and 15 men. In fifteen (48.4%) patients, microbiological examination of epilated eyelashes was positive. The results of forms filled by the patients concerning known subjective clinical symptoms of ocular demodicosis revealed no significant differences between the group with positive and negative results of microscopic examination. The presence of Demodex tails and madarosis observed during dermoscopic assessment correlated positively with positive results of microscopic examination. At least one Demodex tail was found in 86.7% (13/15) cases with positive results of microscopic examination. In the two remaining cases microscopic evaluation showed the presence of Demodex brevis. In 37.5% (6/16) of patients with negative results of microscopic examination, videodermoscopy showed the presence of Demodex tails. Conclusions: Videodermoscopy may facilitate the diagnostics of ocular demodicosis. Patients reporting clinical symptoms suggesting ocular demodicosis but negative results of videodermoscopic examination should be referred to classical microscopic examination to exclude the presence of Demodex brevis. In patients with negative microscopic examination results and symptoms suggesting ocular demodicosis, dermoscopy-guided microscopic re-evaluation could be considered.
