Nasal lymphoma is an uncommon neoplasm in the sinonasal tract. The NK/T-cell type of lymphoma is more commonly found in Asian populations. However, B-cell lymphoma is more common in the western countries whereas it is rare in Asia. Recently, we experienced two cases of sinonasal B-cell lymphoma, which are rare cases in Korea, one in an advanced stage and one in an early stage. Both patients had no specific nasal symptoms or systemic B symptoms (fever, night sweat, weight loss). As our cases demonstrate, diagnosis of B cell lymphoma is often delayed in many cases because B-cell lymphoma does not show any specific symptoms. Thus, careful physical examination and biopsy under suspicion of malignancy are important for early diagnosis of nasal lymphoma.
