Reviewer Information: Brandon Possum, HT(ASCP), is a histotechnologist with over a decade of specialized experience in Mohs histology at Memorial Sloan Kettering Cancer Center. He is board-certified by the American Society for Clinical Pathology (ASCP) and holds a New York State Histotechnician (HT) license.
Brandon began his career with a strong foundation in traditional histology through his formal college education before advancing into the specialized field of Mohs frozen sectioning. In addition to his clinical work, Brandon is actively engaged in professional education. He regularly participates in speaking engagements and educational sessions focused on Mohs histology.
Course Description: This course introduces the fundamental differences between routine histology and Mohs micrographic surgery. It will explore how each laboratory functions, compare workflows, and understand the distinct roles of diagnosis versus treatment in patient care.
