Rosai Dorfman Disease —A rare case of cervical lymphadenopathy

Rosai Dorfman disease is a rare cause of sinus histiocytosis with massive lymphadenopathy. In developing countries, it often mimics some infectious diseases and malignancies and is often mismanaged. A high index of suspicion is necessary for its diagnosis. It is seldom life threatening therefore observation is currently the best advocated approach for its management.
