A Case of Nasal Cavity and Laryngeal Involvement of Rosai-Dorfman Disease.

Rosai-Dorfman disease (RDD) is a rare non-malignant disorder, characterized by painless multiple cervical lymphadenopathy, fever, and elevated inflammatory markers. Its diagnosis is difficult due to its rare incidence and various clinical presentations, especially in extranodal involvement. In this report, we demonstrate a patient with RDD who presented with a nasal septum and laryngeal tumor that caused dyspnea. We achieved a successful treatment outcome with combined surgical resection of the laryngeal mass and corticosteroid medication. The symptoms and tumors were resolved within 3 weeks after treatment. We reported our experiences with review of literatures.
