Rosai Dorfman Disease: A Rare Cause of Cervical Lymphadenopathy

Abstract

Rosai Dorfman disease, a sinus histiocytosis, is rare to find and difficult to diagnose. It may masquerade as commoner diseases including infections and malignancies. Imaging may yield ambiguous results and it is often the histopathology that clinches the diagnosis. Hereby, we report two cases of Rosai Dorfman disease both presented with nasal mass and neck nodes. We present these cases to emphasise the difficulty in clinical diagnosis and to illustrate the pathognomonic pathological findings.
