Lacrimal gland tumor

Lacrimal gland tumors have the highest incidence among primary orbital tumors, and mixed lacrimal gland tumors are the most common, with benign and malignant tumors. Benign lacrimal gland tumors are more common in middle-aged people and have a long course of disease. They originate from lacrimal ducts or acinars, and can also originate from para-lacrimal glands and congenital embryonic tissue residues (primary lacrimal glands). Malignant lacrimal gland tumors lack or have no intact capsule, and the masses adhere to the orbital margin, and there is tenderness at the orbital margin of the adhesion. In addition to the structure of benign lacrimal gland tumors, the tumor tissue is also composed of cancerous tissue. Tumor tissue infiltrates into the orbit, destroys bone, and can lead to systemic metastasis. In severe cases, metastasis to the skull can be life-threatening.
