Özet

Aim: Demodex species are common ectoparasites inhabiting human hair follicles and sebaceous glands. While usually considered part of the normal skin flora, their overgrowth has been associated with dermatological conditions such as blepharitis, rosacea, and acneiform lesions. Methods: This retrospective study analyzed superficial skin biopsy samples from 938 patients referred to the parasitology laboratory of our hospital for Demodex testing between June 2020 and June 2025. Results: Of the 938 patients, 528 (56.3%) were positive for Demodex spp. Among positive cases, 74.8% (395/528) were female and 25.2% (133/528) were male, with no statistically significant difference between genders (p=0.12). The highest positivity rate was observed in the 46–60 age group (30.1%). Conclusion: This five-year retrospective analysis provides epidemiological data on Demodex spp. infestation in a large patient cohort. The findings emphasize the potential role of Demodex spp. in dermatological disorders and contribute to a better understanding of its prevalence in routine clinical practice, supporting future research on regional and population-based variations.
