We report 3 cases of extraocular muscle involvement by MALT (mucosa-associated lymphoid tissue) lymphoma. The first case was a 68-year-old woman who presented with mild proptosis of the left eye and diplopia caused by a lymphoma in the medial rectus. The other two cases presented with ptosis caused by a lymphoma in the most anterior aspect of the levator muscle. MALT lymphoma may involve extraocular muscles, either as a primary or secondary presentation. Although localization of orbital lymphoma in extraocular muscles is rare, this possibility should be considered in the differential diagnosis with other conditions involving extraocular musculature.
我们报告了3例黏膜相关淋巴组织（MALT）淋巴瘤累及眼外肌的病例。首例为一名68岁女性，因内侧直肌淋巴瘤出现左眼轻度眼球突出和复视。另外两例因提上睑肌最前部的淋巴瘤出现上睑下垂。MALT淋巴瘤可作为原发性或继发性表现累及眼外肌。尽管眼眶淋巴瘤定位于眼外肌的情况罕见，但在与其他累及眼外肌的疾病进行鉴别诊断时应考虑到这种可能性。
