Board-certified dermatologist Yan Wang, MD practices in Chula Vista's Eastlake corridor on East Palomar Street, providing medical dermatology through the Sharp Rees-Stealy Medical Group. As a Sharp Rees-Stealy physician with privileges at Sharp Chula Vista Medical Center, the practice coordinates within a multi-specialty system that includes ophthalmologic care from Gregory M. Steele, OD at the Otay Ranch campus. The dermatology scope includes diagnosis and treatment of skin cancer, psoriasis, eczema, acne, rosacea, and solar purpura, with surgical excision protocols for malignant and pre-malignant lesions. Topical and systemic dermatologic prescriptions frequently route through local dispensaries including Chula Vista Pharmacy for both standard fills and compounded formulations. The practice's most complex diagnostic work involves full-body skin cancer surveillance with dermoscopic evaluation, punch and excisional biopsy with specimen orientation marking, and cryosurgical destruction of actinic keratoses using liquid nitrogen at minus 196 degrees Celsius.
