Eyelid swellings are common ophthalmic disorders that manifest as raised masses on the eyelid. The swellings vary in location, size range, and color and can basically be divided into two categories: benign and malignant tumors. Benign tumors of the eyelid are more commonly seen as pigmented tumors (black or brownish-black); hemangiomas (red or dark red, usually soft); and yellow tumors (yellowish-white, usually located on the nasal side of the upper eyelid). 2. Malignant tumors of the eyelid When swellings appear on the eyelid in the elderly, we should be alert to whether they are malignant or not. The more common ones are: 1. Basal cell carcinoma of the eyelid: a mild elevation on the skin surface of the eyelid with uneven edges, surface ulcers, easy bleeding, and may be accompanied by pigmentation; 2. Adenocarcinoma of the lid: rough conjunctival surface of the eyelid, yellowish-white spotted hard nodules, not smooth, congested, and may break down when the tumor is necrotic; 3. Squamous cell carcinoma of the eyelid. Mostly seen as a limited elevation on the lid margin, irregular in shape, dark in color, hard in texture, can also be significantly larger, can be papillary or cauliflower-shaped, and can also form ulcers and infections; 4. Malignant melanoma of the eyelid: mostly starts at the lid margin, develops toward the skin or conjunctival surface, has varying shades of pigmentation, often breaks down and bleeds, small nodular or larger masses. Eyelid swellings should be examined promptly, and because they are close to the eye, they are usually difficult to treat with laser therapy and usually require surgical removal. After removal of the swelling there will be varying degrees of tissue loss, and the surgeon will have to repair the defect depending on the size of the area, so if the swelling is large before considering surgery, it will make the surgery more difficult and increase the post-operative scarring, affecting the post-operative results and appearance. After the swelling is removed, it should also be sent for pathological examination to clarify the nature of the lesion.
