Dermatopathology is the study of skin, hair, and nail samples under the microscope to diagnose diseases and tumors. Gwinnett Dermatology has a CLIA-certified, state-of-the-art dermatopathology laboratory located within our Loganville office. Skin biopsies are processed on site, and interpreted by our board-certified dermatopathologist, Jessica J. Mercer M.D. Dr. Mercer’s skill in dermatology and dermatopathology allow for thorough evaluation of biopsies, and diagnostic and therapeutic guidance to providers. The advantage of having an on-site laboratory and dermatopathologist are enhanced communication of clinical information, better delivery of biopsy results, and improved efficiency.
