The word "tumor" is used in medicine whenever there is an unusual growth of tissue. For patients, however, this word is usually synonymous with malignant cancer. Please do not confuse these two terms.

First, a distinction should be made between inflammatory swelling in the eyelid area and "extra tissue." The eyelid tissue is delicate and even a slight inflammation can lead to a massive swelling of the eyelids. There are many causes for such an inflammation, for example an inflamed lacrimal gland or an infection caused by a minor injury.

If there is a real "extra tissue", i.e. a tumor, it is often a benign change such as an encapsulated sty, a wart, or a so-called molluscum contagiosum, caused by a harmless but contagious virus.

However, various malignant tumors (carcinomas) can also occur on the eyelids. The most common malignant tumor of the eyelids is basal cell carcinoma (90%). Other types are squamous cell carcinoma (about 5%) and sebaceous gland carcinoma (about 5%). In all cases, if a malignant tumor is suspected, prompt action should be taken. If necessary, we will consult specialists from other disciplines such as internists, dermatologists or oncologists (cancer specialists).

Malignant forms of cancer on the eyelid

Basaliomas: 90% of all malignant eyelid tumors. Basaliomas develop when the skin is exposed to intensive sunlight for many years, preferably in fair-skinned people. Basaliomas grow locally and only extremely rarely form daughter tumors (metastases) to other parts of the body.

Squamous cell carcinomas: account for about 5% of malignant eyelid tumors. Excessive sun exposure also plays a role here. The lower eyelid, as with basal cell carcinoma, is more commonly affected because it receives a lot of sunlight. Squamous cell carcinoma metastasizes in about 20% of cases, first to the lymph nodes of the ear and jaw.

Sebaceous gland carcinomas: account for about 5% of malignant eyelid tumors. Develops when a sebaceous gland degenerates. This tumor is aggressive and metastasizes early.

the operation

For small tumors, a biopsy is taken first. This requires a short outpatient procedure. The material is sent to a laboratory and examined under a microscope to confirm the diagnosis. In a second operation, the tumor is removed.

For large tumors, the tumor is removed with a safety margin. This often requires general anesthesia. This is followed by a frozen section diagnosis, i.e. the pathologist immediately examines the removed material under the microscope and informs us 1-2 hours after removal whether the cut edges are free of the tumor. Subsequently, the reconstruction of the eyelid is performed in a second operation on the same day.
 

After removal of the tumor and frozen section diagnosis, the eyelid can be reconstructed. There are a variety of surgical options for eyelid reconstruction. In general, eyelid reconstruction has made tremendous progress in the last 2 decades. Previously, large plastic surgeries of the entire midface were performed to replace one eyelid, or even the eyelids and eye were removed entirely. Fortunately, thanks to improved techniques, this "radical" surgery is no longer used in the vast majority of cases.

Nowadays, defects of all sizes up to complete eyelid replacements can be covered by material originating from the area around the eyelids. Which method is used depends on how much eyelid needs to be removed, i.e. how large the defect to be covered is. Modern surgical techniques range from direct closure to grafts of skin, muscle or connective tissue sheets taken from the upper/lower eyelid of the same side or from the eyelids of the other, healthy eye.

In rare cases, skin is necessary, which is taken from behind the ear.

In some of the modern procedures it is also necessary to operate on two sides: the eyelid is reconstructed and the eye cannot be opened for about 10 days. Then another (short) operation is performed to complete the reconstruction.

The priority in tumor surgery of the eyelids is that the carcinoma is completely removed. Of course, cosmetics are also taken into account, but the former is vital, the latter is not. In the case of large tumors, it may have to be expected that even after successful surgery, the eyelid will not look exactly as it did before surgery.

If a skin graft is required, the graft may also have a different shade than the surrounding skin as a long-term consequence.

Even after complete removal of the carcinoma, there is still a risk of its recurrence years after surgery. Please be prepared for the fact that in the first 3 years after the operation, 6-monthly check-ups with us will be necessary. Later, the intervals between the controls can be increased.
