In the United States, approximately 1 person in 2500 seeks ophthalmic care for a tumor of the eyelid or ocular surface each year, or about 100,000 per year. Benign neoplasms of the eyelid and ocular surface are at least 3 times more common than malignant lesions. Most of these tumors arise from the eyelid skin; they are discussed in BCSC Section 4, Ophthalmic Pathology and Intraocular Tumors, and Section 7, Oculofacial Plastic and Orbital Surgery.
Tumors of the conjunctiva and cornea are considered together because the lesions can affect both tissues concurrently. These lesions are classified by cell type: epithelium, melanocytes and nevus cells, vascular endothelium, mesenchymal cells, and lymphocytes. Many are analogous to lesions affecting the eyelid.
