Rare Extranodal Manifestation of Rosai-Dorfman Disease Presenting as Nasal Obstruction and its Management.

Rosai-Dorfman disease (RDD) is a rare and benign lymphoproliferative disorder that commonly presents as painless, bilateral neck swelling. Extranodal presentations are considered rare, but the most common extranodal locations involved include skin, subcutaneous followed by nasal/paranasal sinuses. Although it is a benign condition, it may be mistaken as a malignant lesion and requires a biopsy for diagnostic confirmation.
