A Case of High-Grade B Cell Lymphoma, Not Otherwise Specified Originating From Interior Turbinate / 대한이비인후과학회지

ABSTRACT

High-grade B cell lymphoma not otherwise specified (HGBL, NOS) is a new diagnostic category of non-Hodgkin lymphoma (NHL) based on World Health Organization statement in 2016. Up to 40% of NHLs are located in the extra-nodal area, commonly involving the gastrointestinal tract, head and neck region, bone and skin. The diagnosis of NHL originating from the inferior turbinate (IT) is rare, and there have been no reported cases yet of HGBL, NOS in IT. In this study, we report on a 43-year-old female who had a nasal polyp in IT and was diagnosed with HGBL, NOS after surgery. Endoscopic polypectomy under general anesthesia was performed. A histopathological report confirmed the resected specimen as HGBL, NOS, with a clear resection margin. Nasal obstruction was improved immediately after surgery and the patient was followed up for 10 months without any recurrence or complications.
