Mohs Micrographic Surgery

Mohs micrographic surgery, also known as Mohs chemosurgery, is a highly specialized procedure for the total removal of skin cancers. This surgery uses a layer-by-layer method of removing skin cancer along with microscopic examination of 100% of the removed tissue margins to ensure complete removal. The procedure yields a cure rate of over 99%.

Together, Dr. Papadopoulos and Dr. Kim have performed more than 20,000 cases of Mohs micrographic surgery. Both are fellows of the American College of Mohs Micrographic Surgery and Cutaneous Oncology, the American Society for Dermatologic Surgery, and the American Academy of Dermatology.

Frequently Asked Questions about Mohs Surgery

How does Mohs surgery work?

Once the affected area is numbed with a local anesthetic, your Mohs surgeon will remove the visible tumor and a thin layer of surrounding tissue (safety margin). The tissue is taken immediately to our in-house laboratory where it is processed and examined by the Mohs surgeon under a microscope. If no evidence of skin cancer exists, the procedure is completed. If the tissue tests positive for skin cancer, the precise location is marked and the physician removes another layer from the area where the cancer was detected. The same process is repeated until the doctor reaches a cancer-free layer.

How long does the procedure take?

Each layer may take 30-60 minutes to process. As a result, Mohs surgery requires patience by both the patient and the physician. Patients should plan to spend half a day at our office.

For what types of skin cancer is Mohs Surgery recommended as a treatment?

Basal cell carcinomas, squamous cell carcinomas and lentigo maligna melanomas are the cancers most commonly treated by Mohs surgery. Less common tumors treated by Mohs surgery include adnexal neoplasms (including desmoplastic trichoepitheliomas), atypical fibroxanthomas, merkel cell carcinoma and dermatofibrosarcoma protuberans (DFSP).

If Mohs Surgery has a 99% cure rate, why isn’t it used to treat all skin cancers?

There are certain and specific criteria that justify the utilization of Mohs surgery to treat a skin cancer. Your dermatologist will evaluate your specific case and suggest the treatment that is most appropriate.
