Massachusetts General Hospital's Dermatologic Surgery Unit offers world-class expertise in Mohs micrographic surgery and a number of other cosmetic surgical procedures.

As the rates of skin cancer have increased in recent years, we have developed streamlined processes that allow us to effectively treat more than 10 cases every day.

What to Expect

Our patients are usually referred to a general dermatologist by their primary care physician if skin cancer is suspected. During their initial consultation here, patients meet with a dermatologist to discuss their medical history and to have their skin cancer lesion examined and analyzed. Using this information, the dermatologist determines whether the patient is a good candidate for Mohs surgery.

The surgery itself is an outpatient procedure. We begin the process by applying a local anesthetic to the affected area (no sedation is required). Next, we excise the tumor for immediate examination and evaluation while the patient waits.

If we discover any cancer cells, the patient returns to the surgical area for the removal of a second layer. Excising all traces of cancerous tissue usually requires one or two cycles, but occasionally more are required. At each step of the process, we are careful to minimize the amount of normal tissue removed. The entire process usually takes just a few hours.

After performing the Mohs technique and the tumor is removed, we discuss with the patient whether reconstructive surgery is necessary. If the wound is small enough, it can be left to heal on its own. If this option is not possible, immediate reconstruction is performed by our cancer surgeon, who is also trained in cosmetic facial surgery.

Communication & Due Diligence

Mohs is a relatively common procedure. Our surgeons frequently exchange findings and best practices with doctors in other hospitals who also perform the surgery. This due diligence allows us to stay abreast of challenges our colleagues are encountering—and to refine our practices accordingly.

Some patients who undergo Mohs or another cosmetic procedure at our unit will require further treatment unavailable in our unit. If so, they benefit from access to the world-class medical professionals and treatment programs available at Mass General.

The Dermatologic Surgery Unit at Massachusetts General Hospital is dedicated to the surgical treatment of skin cancer. We specialize in a minimally invasive procedure known as Mohs micrographic surgery.

In addition, we offer a number of other cosmetic dermatology and aesthetic services, such as:

  • Photodynamic rejuvenation, in which we use intense pulsed light to treat various skin conditions
  • Liposculpture, in which we sculpt areas of the body through fat removal
  • Anti-aging cosmetic dermatology

What Is Mohs Surgery?

When people learn they have a skin cancer lesion on their face or another prominent area, they are usually worried about their health—and potential scarring associated with surgery. Mohs surgery was developed to address both of these concerns.

Cancer surgery involves the excision of both healthy and nonhealthy tissue for analysis and tumor removal. The microscopically controlled Mohs technique limits the amount of tissue that must be removed for these purposes. In addition, it allows the surgeon to analyze the tissue as it is removed, minimizing the wait time for the patient.

Patients undergoing Mohs surgery can experience less scarring compared to traditional surgery; in fact, 50 to 60 percent lose less normal tissue using this technique. Mohs also is highly effective—its cure rate in treating both basal cell carcinoma (the most common type of skin cancer) and squamous cell carcinoma is at least 98 percent.

The Mohs Experts

The Mass General Dermatologic Surgery Unit was one of the first programs in Boston to offer Mohs surgery. Director Victor Neel, MD, PhD, a board-certified dermatologist, has completed more than 17,500 Mohs procedures, making him one of the city's most experienced and knowledgeable Mohs surgeons.

Our doctors are also involved in clinical research and trials. Dr. Neel has a particular interest in skin cancer, and his research into the disease is ongoing.

Basal Cell Carcinoma

Basal cell cancer, sometimes called non-melanoma skin cancer, usually appears as a small, fleshy bump or nodule on the head, neck, or hands. Occasionally, these nodules appear on the trunk of the body, usually as flat growths.

Basal Cell Nevus Syndrome (Gorlin Syndrome)

Basal cell nevus syndrome is caused by a tumor suppressor gene, called PTCH, located on chromosome 9. Mutations in this gene may increase the risk of ovarian cancer.

Excessive Sweating

Excessive sweating, also called hyperhidrosis, can affect the entire body, but usually occurs in the palms, soles, armpits, and/or groin area.

Merkel Cell Cancer

Merkel cell cancer is also known as neuroendocrine cancer of the skin, or trabecular cancer.

Skin Cancer

Skin cancer is a malignant tumor that grows in the skin cells and accounts for more than 50 percent of all cancers.

Squamous Cell Carcinoma

Squamous cell skin cancer (sometimes referred to as non-melanoma carcinoma) may appear as nodules, or as red, scaly patches of skin.
