Mohs Surgery Fellowship

The Advanced Dermatologic Surgery Post-Graduate Fellowship

The section of Dermatologic Surgery and Cutaneous Oncology within the Department of Dermatology at the Yale School of Medicine sponsor an Advanced Dermatologic Surgery Fellowship. The fellowship is approved by the American College of Mohs Micrographic Surgery and Cutaneous Oncology. The Section started in 1988 and has grown to the largest cutaneous surgery program in New England. Close collaborative relationships exist with the sections of plastic surgery, otolaryngology, radiation therapy, and medical oncology. The faculty and staff serve a catchment area of greater than 3,000,000 people, and regional dermatologists, plastic surgeons, head and neck surgeons, and ophthalmologists refer most of the patients we treat. The Unit performed approximately 3,500 Mohs surgery cases in the past year. Approximately 70% are reconstructed in the Mohs Unit. A specially developed electronic medical record and a digital imaging archive system enhance the ability to take advantage of the case material for educational and research purposes.
