A Case of Diffuse Large B-Cell Lymphoma of Sinonasal Tract with Acute Visual Disturbance / 대한이비인후과학회지

ABSTRACT

Malignant lymphoma of the sinonasal tract is relatively uncommon. In particular, B-cell lymphoma is hardly found in the Asian population although the NK/T-cell type of lymphoma is relatively commonly found. The authors experienced a case of diffuse large B-cell lymphoma originating from the ethmoid sinus, which caused the unexpected visual disturbance without nasal symptoms and/or systemic B symptoms, such as fever, night sweat, and weight loss. Diagnosis of B cell lymphoma is often delayed because it does not always show the specific symptoms of lymphoma. Therefore, starting with careful physical and imaging studies are always important while higly suspecting malignancy. Furthermore, early precise biopsy is of great important for precise diagnosis and proper management for the treatment of malignant lymphoma.
