The most common eyelid malignancy is:

Explanation:
Basal cell carcinoma is the most common eyelid malignancy because sun exposure frequently affects the eyelid skin, and basal cells are the cell type from which these tumors arise. It tends to grow slowly and cause local destruction rather than spreading elsewhere, which is characteristic of its behavior. Clinically, it often presents as a pearly, nodular lesion with fine telangiectasias on the lower lid, a region most exposed to sunlight. While squamous cell carcinoma, melanoma, and sebaceous carcinoma can occur on the eyelid, they are less common, with squamous cell being the next most frequent but still far less common than basal cell carcinoma.
