title: [Case report of rheumatoid arthritis associated with type A gastritis and Hashimoto thyroiditis].
abstract: A 59-year-old woman was initially thought to have either type A gastritis, or autoimmune gastritis by upper-gastrointestinal-tract endoscopy and a serological examination. Furthermore, the patient was also suspected to have Hashimoto disease based on a positive antithyroid-antibody test. Rheumatoid arthritis was diagnosed 1 year later. Pernicious anemia, gastric-carcinoid and stomach cancer are the primary complications of A type gastritis. However, we hypothesized that the development of other autoimmune diseases, such as autoimmune thyroid disease, was the primary complication experienced in this case. Therefore, we report the findings of this case while taking into consideration the findings of several other previously published studies.
