Liang Deng, MD, PhD

I am a board-certified dermatologist who specializes in the diagnosis and treatment of various skin conditions — particularly skin cancers including melanoma (the most dangerous form of skin cancer), genetic skin disorders, drug hypersensitivity reaction, therapy-induced skin toxicity, and skin manifestations of infections in immune-compromised individuals.

Most of the patients I care for have prior histories of skin cancers. I have several goals as their dermatologist:  1) to provide the best care possible for the treatment of their newly diagnosed skin cancers; 2) to examine their skin carefully in order to detect skin cancers at an early stage; and, 3) to educate them about sun protection and skin self-examination. Early detection of melanoma can save lives. For patients with many atypical moles and who carry high risks for developing melanoma, whole-body photography is a useful tool to assist dermatologists and patients to identify new or changing moles. I work closely with my colleagues on the melanoma disease management team, which is made up of doctors from medical oncology, clinical immunology, surgery, dermatology, and radiation oncology.
