Background: The pathogenesis of granuloma annulare (GA) is unclear. Collagen fiber degeneration is commonly reported, and there are several conflicting studies on elastic fiber and vascular changes associated with GA. In this study, we aimed to evaluate histopathologic characteristics, collagen and elastic tissue changes and vascular changes in GA.
