Inherited Basaloid Neoplasms Associated With SUFU Pathogenic Variants

期刊介绍:
JAMA Dermatology is an international peer-reviewed journal that has been in continuous publication since 1882. It began publication by the American Medical Association in 1920 as Archives of Dermatology and Syphilology. 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.
JAMA Dermatology is a member of the JAMA Network, a consortium of peer-reviewed, general medical and specialty publications. It is published online weekly, every Wednesday, and in 12 print/online issues a year. The mission of the journal is to elevate the art and science of health and diseases of skin, hair, nails, and mucous membranes, and their treatment, with the aim of enabling dermatologists to deliver evidence-based, high-value medical and surgical dermatologic care.
The journal publishes a broad range of innovative studies and trials that shift research and clinical practice paradigms, expand the understanding of the burden of dermatologic diseases and key outcomes, improve the practice of dermatology, and ensure equitable care to all patients. It also features research and opinion examining ethical, moral, socioeconomic, educational, and political issues relevant to dermatologists, aiming to enable ongoing improvement to the workforce, scope of practice, and the training of future dermatologists.
JAMA Dermatology aims to be a leader in developing initiatives to improve diversity, equity, and inclusion within the specialty and within dermatology medical publishing.
