JAMA Dermatology (formerly the Archives of Dermatology) has been in continuous publication since October 1882. It began publication by the American Medical Association in 1920 as Archives of Dermatology and Syphilology; in 1955, it continued publication as Archives of Dermatology. It is an international peer-reviewed journal published 12 times a year; the online version is published on the third Wednesday of the month. A Middle Eastern and an Indian edition are published bimonthly. The journal publishes material that helps in the development and testing of the effectiveness of diagnosis and treatment in medical and surgical dermatology, pediatric and geriatric dermatology, and oncologic and aesthetic dermatologic surgery. Annually, the journal publishes theme issues on topics selected by the editors of The JAMA Network as being of importance to the health of the nation, such as comparative effectiveness research (2012), infectious disease and immunology (2011), and cancer of the skin (2010).
