Abstract

Abstract – Introduction: Rosai-Dorfman disease (RDD) is a rare, benign histiocytic disorder that can present as isolated cutaneous RDD (CRDD), often mimicking other dermatologic conditions and complicating diagnosis. Case Presentation: We report two cases of CRDD: one with palms and soles involvement, and another as an exophytic facial mass, initially misdiagnosed and unsuccessfully treated. Dermoscopy revealed distinctive features, including yellow ovoid structures, linear vessels, and cotton-like white globules. Histopathological and immunohistochemical analyses confirmed CRDD with histiocytic infiltration and emperipolesis, key histological markers of CRDD. Conclusion: A review of 53 cases (2018–2023) highlights CRDD’s clinical variability, common anatomical sites, and diverse treatment responses, emphasizing the need for individualized management and early recognition for optimal treatment. These findings contribute to a broader understanding of CRDD and support a multidisciplinary approach to optimizing patient care. © 2025 S. Karger AG, Basel
