Mario E. Lacouture is a board-certified dermatologist with special interest in the dermatologic side effects of cancer treatments. His clinical focus is the recognition and management of the side effects and conditions of the skin, hair, and nails that may arise in cancer patients and survivors as a consequence of chemotherapy, radiation, or transplantation. His research focuses on exploring new skin treatments that do not interfere with the effectiveness of anticancer drugs. Dr. Lacouture received his MD degree in 1997 from Javeriana University, in Colombia. He completed residencies at Cleveland Clinic Foundation and the University of Chicago Hospital, and a fellowship at Brigham and Women’s Hospital.
