Clinicopathologic review of 142 cases of lacrimal gland lesions

Abstract

A review of 142 lacrimal gland biopsies performed during a 25-year period at a major eye hospital showed that 78% of lacrimal gland lesions were of nonepithelial origin and only 22% were primary epithelial neoplasms. The nonepithelial lesions included inflammation (64%) and lymphoid tumors (14%), whereas the epithelial lesions included dacryops (6%), pleomorphic adenoma (12%), and malignant epithelial tumors (4%). These results contradict the much quoted dictum that 50% of lacrimal gland lesions are primary epithelial tumors and 50% are nonepithelial lesions.
