Lacrimal gland tumors have the highest incidence rate among primary orbital tumors, and lacrimal gland mixed tumors are the most common among them, with two types: benign and malignant. Benign lacrimal gland mixed tumors are more common in middle-aged people, with a long course of disease, originating from the lacrimal duct or alveoli, and can also originate from the accessory lacrimal gland and congenital embryonic tissue residues (tear gland primordium). Malignant lacrimal gland mixed tumors lack or have no complete capsule, and the mass is adhered to the orbital margin, and there is tenderness at the orbital margin at the adhesion site. In addition to the structure of benign lacrimal gland mixed tumors, the tumor tissue also has cancerous tissue composition. The tumor tissue infiltrates into the orbit, destroys the bone, and can metastasize throughout the body. In severe cases, it metastasizes to the brain, endangering life.
