As a dual board-certified dermatologist and dermatopathologist practicing in Chula Vista since 1975, Dr. Cole B. Willoughby, MD operates the Dermatology and Laser Center on F Street. His skin cancer program includes Mohs micrographic surgery and electronic brachytherapy for non-melanoma carcinomas — a treatment sequence that may involve post-surgical radiation coordination with South Bay Radiation Oncology for complex or recurrent lesions. He earned his medical degree from Ohio State University College of Medicine in 1968, completed a dermatology residency at Brooke Army Medical Center in San Antonio, and trained in dermatopathology at the Armed Forces Institute of Pathology in Washington, D.C. before serving as assistant chief of the dermatology training program at Tripler Army Hospital in Hawaii. His practice handles cosmetic procedures including Botox, dermal fillers, and photofacials alongside medical dermatology and in-house surgical pathology interpretation, with operating privileges at Sharp Chula Vista Medical Center for excisions requiring hospital-level anesthesia. The electronic brachytherapy unit delivers targeted superficial radiation in fractionated doses to treat basal cell and squamous cell carcinomas without the deep-tissue disruption of traditional wide-margin excision.
