■上球脉络膜瘤是一种良性的先天性病变,在异常的异位位置包含组织学上正常的组织。球外脉络膜瘤分为球外皮样,皮脂瘤,或基于组织学检查的复杂脉络膜瘤。出现的病例是假定的上皮脂瘤,影像学上没有骨化的迹象,考试,或术中直到对标本进行组织学检查,明确病变为球外复杂脉络膜瘤。令人放心的是,此类病变中骨的存在不应改变治疗方式.
一位母亲注意到她9岁女儿的上颞球结膜上有一个小的肉质肿块。MRI证实了可疑的球上皮皮脂瘤,并最初进行了保守治疗。两年后,她因明显的增长和美容问题而被推荐,她接受了手术切除.
■我们介绍这个病例的异常表现和组织学发现。眼眶外科医生应意识到球外脉络膜骨化的可能性,并避免与其他诊断混淆。提供了最新的球外脉络膜瘤分类系统的澄清。
UNASSIGNED: Epibulbar
choristoma is a benign congenital lesion containing histologically normal-appearing tissue in an abnormal ectopic location. An epibulbar
choristoma is classified as either epibulbar dermoid, dermolipoma, or complex
choristoma based on histological examination. The
case presented was a presumed epibulbar dermolipoma with no signs of ossification on imaging, examination, or intraoperatively until the specimen was examined histologically, clarifying the lesion as an epibulbar complex
choristoma. Reassuringly, the presence of bone in such lesions should not change management.
UNASSIGNED: A mother noticed a small fleshy mass on her 9-year-old daughter\'s superotemporal bulbar conjunctiva. The suspected epibulbar dermolipoma was confirmed with MRI and initially managed conservatively. Two years later, she was referred for apparent growth and cosmetic concerns, and she underwent surgical debulking.
UNASSIGNED: We present this
case for its unusual presentation and histological findings. Orbital surgeons should be aware of the possibility of ossification of epibulbar choristomas and avoid confusion with alternative diagnoses. Clarification of the latest classification system for epibulbar choristomas is provided.
