There are cases in which the presence of a foreign body (FB) is difficult to diagnose based on history taking or clinical examination. We report a case of subconjunctival FB confused with uveal prolapse. A 68-year-old man, who had the history of pterygium excision in his right eye, complained of irritation and congestion in that same eye. He also had the history of growing vegetables in a plastic greenhouse. It seemed to be a suspected uveal mass bulging through a focal scleral thinning site. On the basis of slit-lamp magnification, the lesion was presumed to be a hard and black keratinized mass embedded under the conjunctiva. Histopathologically, the removed mass was revealed to be a seed of the dicotyledones. Patients who show signs of prolapsed uvea or scleral thinning, possibility of a subconjunctival FB should be considered as differential diagnosis. In addition, a removed unknown FB should be examined histopathologically.
在某些情况下，根据病史采集或临床检查很难诊断出异物（FB）的存在。我们报告一例结膜下异物被误诊为葡萄膜脱垂的病例。一名68岁男性，右眼有翼状胬肉切除史，主诉同一眼有刺激感和充血。他还有在塑料温室种植蔬菜的经历。病变似乎是一个疑似葡萄膜肿物通过巩膜变薄部位突出。在裂隙灯放大检查的基础上，推测病变是一个嵌入结膜下的坚硬黑色角质化肿物。组织病理学检查显示，切除的肿物是双子叶植物的种子。对于表现出葡萄膜脱垂或巩膜变薄迹象的患者，应考虑结膜下异物作为鉴别诊断的可能性。此外，切除的不明异物应进行组织病理学检查。
