Abstract
Rosai–Dorfman disease (RDD) is a rare and self-limiting disease process that presents most commonly in young patients as massive, painless, cervical lymphadenopathy. Extranodal involvement may also occur. Histopathologic evaluation is the main diagnostic modality. We report an unusual presentation of RDD with cervical lymphadenopathy and an incidentally discovered sinonasal mass, clinically worrisome for malignancy. We emphasize that a high index of clinical suspicion is critical for accurate diagnosis of RDD. Clinicians and pathologists should consider RDD in a differential diagnosis of cervical lymphadenopathy, especially in young patients.
