Rosai‐Dorfman Disease in a 4‐Month‐Old Female Presenting With Cervical Lymphadenopathy

Abstract

ABSTRACT Rosai‐Dorfman disease is a rare histiocytic disorder that can mimic malignancies. This case highlights the importance of immunohistochemistry in distinguishing RDD from lymphoproliferative neoplasms, ensuring accurate diagnosis and management. Clinicians should consider RDD in unexplained soft tissue masses to avoid misdiagnosis and unnecessary interventions.
