A personal message from Dr. Tomayko to her patients:

During this time of the COVID-19 pandemic, please know that I continue to be available to work with you to maintain your skin health. I am scheduling video visits and telephone visits. The goal is to protect your health by minimizing physical face-to-face contact while maximizing our continued communication.

If you would like to do a video visit, please contact our office. We will provide specific instructions to you about how to prepare to ensure the visit is as productive as possible. For a video visit, you will need an Epic MyChart account and have the MyChart app installed on your mobile device. Our office can help you with this. If you are unable to do this, we will do a telephone visit instead. Please take care of yourselves and loved ones by practicing social distancing by sheltering at home. Take you temperature twice daily, wash your hands frequently and avoid touching your face, nose and mouth. If you have an elevated temperature, cough, sore muscles or other symptoms of even mild illness, distance yourself from your loved ones and call your primary doctor. This is a challenging time, but we will get through it together.

Mary M. Tomayko, M.D., Ph.D

Mary Tomayko M.D., Ph.D., is a physician scientist who brings insight from her inflammation and immunity research to her medical dermatology practice. Dr. Tomayko is an attending physician at Yale New Haven Hospital, Yale Health and  Yale Dermatology Associates. She evaluates and treats adults and children with complex dermatologic conditions, including autoimmune and inflammatory disorders. particularly autoimmune blistering disease, psoriasis, atopic dermatitis, vitiligo and  lupus. She employs a range of treatment modalities, including systemic immunomodulators, targeted “biologic” agents and phototherapy. Additionally, performs surgical excisions of skin cancers and other skin lesions.

Dr. Tomayko directs a dermatology research laboratory that works to understand how the immune system functions in health and how dysregulation can lead to autoimmune skin disease.  She has identified molecular pathways required for the development of lasting immunity, including durable antibody titers. She has uncovered unexpected diversity in phenotype and function of the cells that maintain immunity, suggesting exciting new therapeutic approaches to enhance or suppress immunity. She has received funding from the National Institutes of Health, the Arthritis Foundation and the Dermatology foundation. Dr. Tomayko publishes peer-reviewed articles and regularly presents her work at national and international meetings. She is a reviewer for scientific and medical journals and foundations.
