Acne vulgaris is an inflammatory disease of the pilosebaceous unit, affecting about 85% of the young population. In the studies p. acne is a potent stimulator of the release of IFN-gamma (IFN-)) and IL-17 from CD4 + T cells, and the presence of IL-17 + cells in the perifollicular infiltrate has been shown in biopsies of inflammatory acne lesions. Therefore, acne is thought to be a Th17-related disease (1).

This study was aimed to evaluate the presence of enthesitis in patients with acne vulgaris.

Bilateral lower extremity tendon thicknesses and the presence of erosion, bursitis, etc. will be evaluated according to the criteria of Guess (Glasgow Ultrasound Enthesitis Scoring System) and Guess score will be determined for all participants. A total of 48 participants, 24 patients with acne vulgaris and 24 healthy controls, will be included in the study (2).
