Common Signs and Symptoms

Most people with Gorlin syndrome have the following symptoms and signs.

Basal cell carcinomas

Also known as basal cell skin cancer, basal cell carcinomas (BCCs) is the most common feature of Gorlin syndrome. About 90% of people with Gorlin syndrome will have one or more BCCs by the age of 35.

BCCs happen when the cells in the bottom layer of the skin (the basal layer) become cancerous. Most basal cell cancers occur on skin that is regularly exposed to sunlight or other ultraviolet light radiation such as what is generated by tanning beds and certain types of lasers. In people with Gorlin syndrome, BCCs can develop in areas of the body that have not been exposed to much sunlight.

Basal cell carcinomas have raised borders that can appear glossy and shiny. BCCs can also be pink, red or skin-colored, and may have darker flecks in them and be dome-shaped, flat, bumpy or scaly. Some BCCs develop a small crater in the center, ooze or bleed easily and crust over.

Basal cell carcinoma is the most common form of skin cancer in the US. One in five Americans (without Gorlin syndrome) will develop a BCC. This type of BCC is called sporadic basal cell carcinoma.

Treatment for basal cell carcinomas (BCCs)

Treatment for BCCs depends on the size, depth and location of the BCCs on the body, the patient’s age and health status. BCC treatment is typically managed by a dermatologist.

A basal cell carcinoma can be classified into subtypes. “Superficial” is the least invasive type of BCC. The other BCC types include nodular, sclerosing and morpheaform, which is the most aggressive. A biopsy and pathology report are the only definitive way to know the subtype.

For more advanced BCCs, surgery may be required.

Knowing the BCC subtype is important to determining treatment. Because a person with Gorlin syndrome is likely to undergo multiple treatments for BCCs over his or her lifetime, the treatment approach is necessarily different than that of the “typical” skin cancer patient who may only undergo one or two surgeries.

There are several different types of treatments for basal cell carcinomas. These include surgery, topical treatments and oral medications. Surgery for BCCs are typically “outpatient” done in the provider’s office with local anesthesia. The patient returns home that day.

Treatments for basal cell carcinomas include:

Mohs surgery removes a thin layer of the BCC tissue. This layer is analyzed for cancer cells while the patient waits. If there is presence of cancer cells, the Mohs surgeon removes another layer for analysis. Once a layer is free of cancer cells, the wound is closed and the surgery is complete. Learn more about Mohs surgery.

Excisional surgery is the removal of the entire BCC growth and some skin around it for a safety margin. The incision area is closed with stitches and the growth is sent to the lab for analysis.

Curettage and electrodesiccation, where the BCC growth is first removed with a special tool and then the area underneath is dessicated, or burned, with a fine needle used specifically for this purpose.

BCC surgery is usually an outpatient procedure.

Cryosurgery destroys the BCC growth by freezing it. Liquid nitrogen is applied directly to the BCC causing the growth to blister, scab over and eventually fall off.

Photodynamic therapy (PDT) destroys BCCs by zapping them with a strong blue light after a topical “activating” agent is applied. Sunlight must be avoided for at least 48 hours after the procedure. PDT is used for superficial (thin BCCs) as it not effective on large or raised (nodular) BCCs. Photodynamic therapy is safer for people with Gorlin syndrome as it does not contain radiation.

Laser surgery, while not yet approved by the FDA for the treatment of superficial BCCs, uses a strong beam of light (the laser) to destroy BCCs.

Topical medications (imiquimod or 5 flurouracil) are applied to the tumor site multiple times of day for up to six weeks, depending on the type of medication.

Oral medications vismodegib and sonidegib are used for advanced cases of BCCs, especially those that are metastatic (spread to other parts of the body). Both of these medications cause severe birth defects and women must take caution to avoid pregnancy while on these medications.

Keratocystic odontogenic tumors

KCOTs grow in the jawbone and can cause tooth loss if not treated promptly.

A keratocystic odontogenic tumors (KCOT) is a benign (non-cancerous) cyst or tumor that grows in the lower or upper jaw bones. The cysts are formed from the cells and tissue that help develop teeth.

KCOTs are often found during routine dental x-rays or when pain, swelling and drainage develop in the area. They may be associated with impacted baby teeth, and can cause problems with the new teeth coming in.

KCOTs can return and must be treated aggressively. If KCOTs are left untreated they continue to grow, pushing out permanent teeth and damaging the jaw bones. They can expand into the sinus cavity and cause discomfort in the cheek(s).

Treatment for KCOTs

Keratocystic odontogenic tumors are treated by oral and maxilla-facial surgeons or otolaryngologists (ear, nose and throat physicians). Treatment for KCOTs is surgery to remove the cysts.

Palmoplantar pits

Pits on the palms of the hands are a common symptom of Gorlin syndrome.

Palmoplantar pits (palmar planter) are small depressions or dots on the palms of the hands or soles of the feet. Most people with Gorlin syndrome have pits – some may have a few of them and others may have hundreds.

The pits look similar to large pores and can be more noticeable when the skin has absorbed water (like after a bath). The words palmar and plantar refer to the areas where they are found most often – on the palms of the hands and the bottoms of the feet.

Treatment for palmoplantar pits

Generally, palmoplantar pits are painless and cause no problems. If the pits grow or change or become infected, consult a health care provider.
