It is characterized by histiocytic proliferation of lymphatic sinuses, which primarily involves the lymph nodes, but has an extranodal tendency. Frequently encountered extranodal sites in the head-and-neck region is paranasal sinuses and nasal cavity, orbit, parotid gland, and middle ear. We present a case of RDD occurring in the nasal cavity of a 28-year-old female from Nigeria. RDD should be considered a differential diagnosis in any patient with benign sinonasal mass especially arising from the nasal septum with massive cervical lymphadenopathy. ER -
