Skin cancer
often involves the skin of the eyelid or adjacent face. Eyelid
skin cancers occur most often on the lower eyelid, but may
be found anywhere on the eyelid margins, corners of the eye,
eyebrow skin, or adjacent areas of the face. Usually, they
appear as painless elevations or nodules. Occasionally, the
eyelashes are distorted or missing. There may be ulcerations
of the involved area, along with bleeding, crusting, and/or
distortion of the normal skin structure. Such findings need
to be evaluated and may require a biopsy to confirm the diagnosis
of skin cancer.
Causes of Skin Cancer
Excessive exposure to sunlight is the single most important
factor associated with skin cancers on the face, eyelids,
and arms. Fair-skinned people develop skin cancers far more
frequently than dark-skinned people. Skin cancers may also
be hereditary.
Types of Skin Cancer
The most common types of skin cancers are basal cell carcinoma
and squamous cell carcinoma. Both types enlarge locally and
usually do not spread (metastasize) to distant parts of the
body. However, with time, if not completely removed, either
type will invade adjacent structures. It is important to know
that basal and squamous cell carcinomas are relatively slow
growing. Thus, when detected early and treated in a prompt
and appropriate manner, there is a better chance of removing
the tumor completely and minimizing the amount of tissue affected
by the carcinoma. Sebaceous gland carcinoma and malignant
melanoma are more serious forms of skin cancer because they
may spread (metastasize) to other parts of the body. These
types of skin cancer require prompt, aggressive treatment
because of the threat of early spread.
Treatment
There are two very important principles in the management
of eyelid skin cancers--complete removal and reconstruction.
Complete removal of the tumor is critical to minimize the
possibility of recurrence, which is even more difficult to
manage. The surgeon may remove the tumor and have a pathologist
check the tissue margins ("frozen section") to be
sure the tumor is completely removed. In another method, a
dermatologic surgeon excises the tumor in a special way ("Mohs
technique") to ensure total removal. Once the tumor has
been completely removed, reconstructive surgery is usually
necessary. Occasionally, the wound can heal on its own through
a process called "granulation." More commonly, reconstructive
surgery is performed to make a new eyelid or repair the defect.
Many excellent techniques are available to reconstruct almost
any surgical defect. The operation will be specifically tailored
to the defect that is present following removal of the tumor.
Regardless of technique, the goals remain the same: to reconstruct
the eyelid so that it functions properly, protects the eye,
preserves vision, and has a satisfactory cosmetic appearance.
Any form of therapy for eyelid skin cancer will leave a scar.
However, an effort is always made to minimize scarring and
obtain optimal cosmetic results. After surgery, the healing
process may take six months to one year. Once the wound has
healed, follow-up with your physician is necessary to be sure
that the skin cancer does not recur. Should there be development
of a new cancer, it can then be detected early and treated
promptly.
Eyelid skin cancers are most commonly
treated by ophthalmic plastic and reconstructive surgeons
who specialize in diseases and conditions affecting the eyelids,
the lacrimal (tear) system, the orbit (bone cavity around
the eye), and adjacent facial structures. Fellowship in the
American Society of Ophthalmic Plastic and Reconstructive
Surgery (ASOPRS) indicates that the surgeon has special training
and expertise in this subspecialty and that he or she is board
certified by the American Board of Ophthalmology or its equivalent.
