Tumors of the lacrimal gland fossa comprise roughly 10% of all orbital masses. There are a wide variety of etiologies for these masses, including infectious, inflammatory, and neoplastic. Furthermore, neoplastic lesions can either be benign or malignant. This activity will focus on benign lacrimal gland tumors. Since the lacrimal gland fossa is in the anterior superolateral orbit, space-occupying lesions of this area of the orbit typically cause inferior and medial globe displacement. Proptosis is not always seen but can be present if the posterior growth of a mass pushes the eye forward. Most benign lesions grow slowly and without pain, so these changes may manifest over long periods of time, averaging 1 to 2 years before diagnosis, compared to 6 months or less for malignant lesions. Many patients report a vague asymmetry of the middle third of the face as their initial, primary concern. Occasionally, lacrimal gland masses are noted incidentally during a routine eye exam or on imaging for an unrelated issue.
泪腺窝肿瘤约占所有眼眶肿物的10%。这些肿物有多种病因，包括感染性、炎症性和肿瘤性。此外，肿瘤性病变可以是良性的，也可以是恶性的。本活动将聚焦于良性泪腺肿瘤。由于泪腺窝位于眼眶前上方外侧，该区域眼眶的占位性病变通常会导致眼球向下和向内移位。并非总是能看到眼球突出，但如果肿物向后生长将眼球向前推，则可能出现眼球突出。大多数良性病变生长缓慢且无疼痛，因此这些变化可能在很长一段时间内才会显现，平均在诊断前1至2年，而恶性病变则为6个月或更短时间。许多患者最初主要关注的是面部中三分之一部位隐约的不对称。偶尔，泪腺肿物会在常规眼科检查期间或因无关问题进行成像时偶然被发现。
