Extranodal Sinonasal Rosai-Dorfman Disease-A Rare Entity

Rosai-Dorfman disease is a distinct non-malignant clinicopathological entity involving both nodal and extranodal tissue. Its clinical presentation can mimick other benign and malignant lesions. We report a lady presented with sinonasal mass suspicious of malignancy. Various investigation modalities were employed to achieve the diagnosis. She was managed conservatively and remained well. This report serves to highlight such rare clinical entity which follows a significantly different natural course than malignant disease despite sharing similar initial presentation.International Journal of Human and Health Sciences Vol. 02 No. 04 October’18.
