A board-certified dermatologist and former faculty member in Immunology, Molecular Oncology, and Dermatology at Washington University School of Medicine, Benjamin Yu, MD earned his MD from Washington University in St. Louis in 1998 and completed his dermatology residency through the Washington University/B-JH/SLCH Consortium in 2002 before relocating his clinical practice to San Diego. At the UCSD Hillcrest dermatology practice at 200 W Arbor Dr, his patient panel includes full-body skin cancer screenings, mole evaluation, and treatment of actinic keratoses for patients cross-managed with internists at Scripps Coastal Medical Center Hillcrest for diabetes and cardiovascular risk factors that influence wound healing after skin cancer removal. His published peer-reviewed research in the Proceedings of the National Academy of Sciences covers the p16INK4a–cyclin D:cdk4/6–retinoblastoma pathway in melanocyte survival and melanoma transformation, supported by CIRM-funded stem cell research on skin cancer biology. Hospital affiliations include UCSD Hillcrest Medical Center and the Jennifer Moreno Department of Veterans Affairs Medical Center, covering inpatient dermatology consults and veteran dermatology care. Outpatient cryosurgery for actinic keratoses, shave biopsies, and excisions for basal cell carcinoma are handled chairside, while subspecialty ambulatory coordination for complex oncologic dermatology routes through nearby UCSD sites including the UC San Diego Health 4th & Lewis Medical Offices. His most scientifically complex work pairs translational melanoma research with clinical management of high-risk pigmented lesions in patients with strong family histories of skin cancer who need genetic counseling and longitudinal surveillance photography.
