Extranodal natural killer (NK)/T-cell lymphoma, nasal type is a rare non-Hodgkin lymphoma originating in the nasal cavity or in the paranasal sinuses, and is etiologically closely related with the Epstein Barr Virus infection. It is more commonly found in East Asia, South America, and Mexico than in Europe or North America. Extranodal NK/T-cell lymphoma, nasal type typically shows a crust on the nasal mucosal surface, necrosis, and inflammation. Pathologically, it presents as significant vascular damage and destruction, with apparent tissue necrosis and cytotoxicity. These neoplasms are very aggressive and can show septal perforation, diffuse ulcer lesion on the nasal mucosa, fistula or epistaxis. We experienced a case of the extranodal NK/T-cell lymphoma, nasal type at the nasal septum, which was delayed in diagnosis due to septal perforation, which occurred after septoplasty in a 47-year-old female. Thus, we report this case with a review of literatures.

Purpose: The aim of this study was to identify the change in hand grip strength (HGS) for consecutive 6 months in breast cancer survivors (BCS) undergoing postoperative adjuvant chemotherapy (adjCTX) and to determine the factors relevant to HGS after chemotherapy completion Methods: This study was a retrospective observational cohort study. BCS (N=38) who underwent breast cancer surgery and subsequent adjCTX were enrolled. The HGS of both sides was measured before adjCTX and 3 weeks, 2 months and 6 months after adjCTX. And we also collected body composition, anthropometric measurements, social demographics and clinical data. Then we analyzed the changes in HGS over time, and correlation of collected data with HGS at 6 months. Results: A significant increase in HGS of the unaffected side was observed within the first 3 weeks of adjCTX and maintained up to 6 months. In correlation analysis, HGS of both sides was positively correlated with the ipsilateral HGS at 3 weeks, and contralateral HGS at 6 months. And skeletal muscle mass was also positively correlated with the HGS of the unaffected side. In addition, subjects treated with targeted therapy had lower HGS of the unaffected side. However, HGS of the affected side was significantly lower in subjects with breast reconstruction and treated without radiotherapy. Conclusions To maintain the early recovery of HGS, active and continuous exercise intervention for strengthening might be necessary.
