title: [Unexpected Diseases in Two Patients with False-Positive Dengue Immunoglobulin M Antibody Test Results].
abstract: In 2014, an outbreak of 162 domestic dengue fever infections occurred in Tokyo, Japan; the first outbreak of its kind in 70 years. Nineteen of these cases were confirmed in our center. Advancements in diagnostic methods have enabled an earlier diagnosis of dengue fever; however, unfamiliarity with the clinical course and characteristics of diagnostic tests for dengue fever can lead to misdiagnosis. We herein describe 2 cases of Japanese patients with false-positive dengue immunoglobulin M antibody test results, who were finally diagnosed as having dermatomyositis and acute hepatitis A infection, respectively.
