Non-Hodgkin’s lymphoma of nasal cavity or sinuses is rare. Usually, it is a NK/T cell lymphoma. The B cell lymphoma is extremely rare in Koreans. B cell lymphoma usually occurs in western people in the paranasal sinuses. Because it presents as a mass in the paranasal sinus, unlike NK/T cell lymphoma, B cell lymphoma can cause sinusitis like symptoms or eye symptoms such as optic neuropathy, telecanthus, exophthalmos. We report a rare case of a huge diffuse large B cell lymphoma in the paranasal sinus with acute visual loss in a 72 year-old female. The patient was successfully treated due to a fast diagnosis and immediate treatment via chemotherapy. (J Clinical Otolaryngol 2011;22:250-254)
