Eyelid lesions (eyelid lumps and bumps) are very common and can be benign or malignant (cancerous). Clinical examination and/or biopsy are required for the definitive diagnosis as to whether they are benign or malignant. There are five main types of benign tumors and five main types of malignant tumors. There are also rarer tumors.
- pigmented lesions
- benign epithelial tumors
- pre-cancerous epithelial tumors
- adnexal and cystic tumors
The majority of small lumps and bumps around the eyelids are benign and can be easily removed in their entirety. However, even a benign looking lump can be a tumor masquerading as benign and the cells have to be analyzed under the microscope to exclude a malignant tumor (histopathological analysis).
The treatment of eyelid lesions depends on the diagnosis which is obtained by biopsy. Benign eyelid lesions are excised in full and ocular reconstruction performed using direct closure, flaps or grafts.
Malignant tumors may require adjuvant treatment with either radiotherapy or chemotherapy after excision, depending on their diagnosis.
Surgery of eyelid lumps and bumps can frequently be done under local anesthetic, with the surgeon assisted by magnification, in the form of surgical loops worn on spectacles, in order to place very fine stitches which are almost invisible.
The result of the histological analysis (examination of the cells) is usually available within a week if deemed necessary by the surgeon.
