Background: Atopic dermatitis (AD) is a chronic inflammatory skin disorder characterized by intense itching and eczematous lesions. Interleukin 17 (IL-17) has been implicated in the pathogenesis of AD, but its expression in the skin tissues of AD patients compared to normal controls remains to be fully elucidated. Understanding the role of IL-17 in AD is crucial for the development of targeted therapies and improved management strategies. This study aimed to assess the level of tissue IL-17 in AD compared to normal control before and after topical mometasone fumarate cream
