A conjunctival inclusion cyst is a colorless or whitish translucent cystic lesion, frequently occurring on the conjunctiva. Here, we describe a patient with a giant conjunctival cyst, mainly existing in the orbit, which clinically resembled lymphatic malformation. A 34-year-old male complained of a subconjunctival mass on his left infero-medial side persisting since childhood. It had gradually enlarged over the 3 months before the initial visit. He had no history of trauma, surgery, or conjunctivitis. The mass was dark red, with superficial dilated blood vessels. Magnetic resonance imaging showed a well-circumscribed mass in the inferior orbit, measuring 12 × 25 mm, which had an internal septum. The lesion was completely resected without rupture of the mass through a transcutaneous approach. Histopathologically, the mass was a cyst composed of columnar epithelium with goblet cells and lymphoid follicles adjacent to the wall. In conclusion, a giant orbital conjunctival cyst and a lymphatic malformation should be differentiated at diagnosis.
结膜包涵囊肿是一种无色或白色半透明的囊性病变，常发生于结膜。在此，我们描述一名患有巨大结膜囊肿的患者，该囊肿主要位于眼眶内，临床上类似于淋巴管畸形。一名34岁男性主诉自幼左眼内下侧存在结膜下肿物。在初次就诊前3个月内肿物逐渐增大。他无外伤、手术或结膜炎病史。肿物呈暗红色，表面有扩张的血管。磁共振成像显示眼眶下部有一个边界清晰的肿物，大小为12×25毫米，内部有隔膜。通过经皮入路完整切除肿物，未发生肿物破裂。组织病理学检查显示，肿物为一个囊肿，由含有杯状细胞的柱状上皮和与囊壁相邻的淋巴滤泡组成。总之，巨大眼眶结膜囊肿和淋巴管畸形在诊断时应加以鉴别。
