Chinese expert consensus on the diagnosis and treatment of epithelial tumors of the lacrimal gland (2021)

Orbital tumors frequently occur in the regions where the lacrimal gland is located. Lacrimal gland tumors account for about 10% of orbital space-occupying lesions. Among them, 20% to 50% were epithelial tumors, with benign tumors accounting for 55% and malignant tumors accounting for 45%. Epithelial lacrimal gland tumors usually have a special location with relatively distinctive manifestations, and the treatment principle is different from other orbital space-occupying lesions. Improper treatment often leads to recurrence and even malignant transformation, which compromise the prognosis and life quality of patients. In view of this, the Oculoplastic and Orbital Disease Group of Chinese Ophthalmological Society has put forward the expert consensus on the diagnosis and treatment of epithelial lacrimal gland tumors after serious discussion, in order to improve the level of diagnosis and treatment of this disease in China.
