Mohs Micrographic Surgery is a highly
specialized, tissue-sparing technique used to treat certain types of skin
cancer. It is considered the gold standard for treating basal cell carcinoma
(BCC), squamous cell carcinoma (SCC), and other select skin cancers,
especially those located on the face, ears, scalp, hands, or other
cosmetically and functionally sensitive areas.
What sets Mohs Surgery apart is its
precision. Unlike traditional excision, Mohs allows for 100% microscopic
examination of the tissue margins during the procedure. Cancerous tissue is
removed in thin layers, and each layer is examined immediately under a
microscope in an on-site lab. This process is repeated until no cancer cells
remain, ensuring complete removal while preserving as much healthy tissue as
possible.
With cure rates up to 98% for BCC and SCC,
Mohs Surgery offers the highest success rate of any skin cancer treatment. It
is particularly beneficial for tumors that are aggressive, recurrent, or
located in areas where cosmetic outcome is a priority.
Developed by Dr. Frederic E. Mohs in the
1930s, the technique has become a global standard in skin cancer care. It is
especially effective in identifying and removing cancer cells that extend
deeper than they appear on the surface, often growing along nerves, blood
vessels, or cartilage.
At Charlotte Dermatology, Mohs Surgery is
performed in-office as an outpatient procedure using local anesthesia. The
process is meticulous but efficient, and patients are encouraged to set aside
the full day in case multiple stages are required.
The procedure involves three main steps:
- Tissue Removal:
After numbing the area with local
anesthesia, the visible tumor is removed along with a thin layer of
surrounding tissue. A detailed map of the excised tissue (a “Mohs map”) is
drawn to track where each section came from.
- Microscopic Examination:
The tissue is color-coded and processed in
our on-site laboratory. A technician freezes the specimen, slices it thinly,
and places it on slides for microscopic examination. This step takes
time—often an hour or more—as it involves reviewing the entire edge and
underside of the tissue.
- Targeted Removal (if needed):
If cancer cells are still detected, only the
precise areas where cancer remains are re-excised. This step is repeated
until all tissue margins are clear, minimizing the removal of healthy skin
and reducing the size of the final wound and scar.
Reconstruction and
Recovery:
Once the cancer has been fully removed,
reconstruction is performed the same day. Depending on the wound's size and
location, this may involve sutures, skin flaps, or grafts. Patients typically
experience mild swelling or bruising, and stitches are removed at a follow-up
visit. Most individuals can return to normal activities within a few days.
Dr. El-Gamal at Charlotte Dermatology ensures
both medical and cosmetic outcomes are carefully addressed. Comprehensive
aftercare instructions are provided, along with guidance on sun protection to
help reduce the risk of future skin cancers.
Mohs Surgery is available at our Charlotte-area
clinics, including SouthPark and University City, where patients receive expert,
personalized care from providers with advanced training in skin cancer treatment.
