Kikuchi-Fujimoto disease (KFD) is a benign, self-limiting disease, with a specific histopathology. It can be diagnosed clinically, and specific symptoms include fever and cervical lymphadenopathy. The histological finding of KFD in cervical lymph nodes includes necrotizing lymphadenitis. KFD needs conservative treatments. If KFD persists for a long period, steroids or nonsteroidal antiinflammatory drugs can be used to control symptoms. Previous studies have reported the treatment of KFD with hydroxychloroquine (HC) in patients unresponsive to steroids. Herein, we report a case of a 25-year-old female patient diagnosed with KFD unresponsive to steroids, and was successfully treated with HC.

Rationale:When a gastric spindle cell tumor is observed, the possibility of synovial carcinoma, besides common mesenchymal tumor, should also be considered.Presenting concerns of the patient:The patient is a 51-year-old American woman who underwent medical check-up at a general hospital. Upper endoscopy showed a 2-cm sized mass covered with intact mucosa, and a central depression located on the posterior wall of the mid body. Biopsy of the mass showed focal atypical cells proliferation in mucosa on hematoxylin & eosin (H&E) staining. Endoscopic ultrasound showed a 17-mm homogenously hypoechoic mass within the submucosal layer.Interventions:After diagnostic endoscopic submucosal dissection was performed, H&E and immunohistochemical staining showed synovial sarcoma (SS). To confirm the diagnosis, reverse transcriptase-polymerase chain reaction was performed, revealing a chimeric transcript of the SYT-SSX1 fusion gene. The diagnosis of primary gastric SS was confirmed because no evidence of possible primary lesions or metastatic lesions was observed. Therefore, the patient underwent distal gastrectomy.Outcomes:After surgery, the surgical specimen demonstrated no residual tumor cells. The patient received no adjuvant therapy, and there has been no evidence of local recurrence or distant metastasis for 2 months after the operation.Lessons:When gastric subepithelial tumor is suspicious, we should also consider gastric SS.

Background/Aims: Many patients uses the internet to obtain information about their diseases. However, there is increasing concern regarding the quality of internet information. Thus, we aimed to systematically evaluate the quality of websites containing educational information about non-alcoholic fatty liver disease (NAFLD) in Korea. Methods: Naver, Daum, and Google search engines were searched using the term "non-alcoholic fatty liver disease" in Korean. Two reviewers independently evaluated website quality using the quality evaluation instrument (QEI), which awarded websites scores for specific information on various aspects of NAFLD, as well as a five-point Likert scale (1-5), the DISCERN instrument, and a global quality scale (GQS). Results: Forty-seven websites met the inclusion criteria. We found that the quality of the internet information about NAFLD is generally poor. The mean QEI score with standard deviation was 10.31 ± 5.09 (range, 4 to 22), with only 17% of websites scoring higher than 10 points. The median GQS of the websites was 2.0, with no website achieving a score of 4 or 5. The QEI score was highly associated with the GQS score (r = 0.74, p < 0.01). For each DISCERN question from question 1 to question 15, the mean score was less than 3. Conclusions: Overall, the internet health information for patients regarding NA-FLD is poor and in need of much improvement. There is a need for institutional support, qualitative regulation of internet information, and development of an accreditation system to provide patients with internet health information of appropriate quality.

Background:The Internet has a wide range of health information resources, and many
