Mohs Micrographic Surgery

Dr. Hyland Cronin is a board certified dermatologist, a diplomate of the American Academy of Dermatology and a fellow of the American College of Mohs Micrographic Surgery and Cutaneous Oncology. She specializes in treating all types of skin cancer onsite at Integrated Dermatology of Chevy Chase.

Mohs micrographic surgery is the most effective treatment for most types of skin cancer. The Mohs procedure involves surgically removing skin cancer layer by layer and examining the tissue under a microscope until healthy, cancer-free tissue around the tumor is reached–called clear margins.

Mohs surgery is unique and so effective because of the way the removed tissue is microscopically examined, evaluating all of the surgical margins. The pathologic interpretation of the tissue margins is done on-site by the Mohs surgeon, who is specially trained in the reading of these slides and is best able to correlate any microscopic findings with the surgical site on the patient.

Advantages of Mohs surgery include:

  • Ensuring complete cancer removal during surgery,
    virtually eliminating the chance of the cancer growing back
  • Minimizing the amount of healthy tissue lost
  • Maximizing the functional and cosmetic outcome
    resulting from surgery
  • Repairing the site of the cancer the same day
    the cancer is removed, in most cases
  • Curing skin cancer when other methods have
    failed
  • Other skin cancer treatment methods blindly
    estimate the amount of tissue to treat, which can result in the unnecessary
    removal of healthy skin tissue and tumor re-growth if any cancer is missed.
