简介：AbstractIntroduction:Pterygium inversum unguis (PIU) refers to a disorder that distal portion of the nail bed adheres to ventral surface of the nail plate, leading to the absence of the distal groove. This is not a common condition in existing literature, thus its pathogenesis has not been elucidated. The occurrence can be congenital, idiopathic, or secondary. Here we present a case of PIU associated with systemic lupus erythematosus (SLE).Case presentation:A 33-year-old woman presented with distal nail bed of the bilateral fingers (excluding the thumbs) adheres to the ventral surface of the nail plate, associated with a malar rash, photosensitivity, and arthritis, whose further laboratory examinations confirmed immunologic disorders. All these clinical characteristics and laboratory results point to the diagnosis of PIU secondary to SLE. Treatment of SLE and topical application of tretinoin 0.025% were performed and resulted in the improvement of most discomforts but PIU. There has no aggravation or alleviation of the PIU during a year of follow-up.Discussion:Acquired form of PIU is reportedly associated with connective tissue diseases or other conditions, which may be caused by abnormal distal circulation or exposure to certain chemical stimuli. Some therapies may be available, while the most effective strategy is to treat potential disorder. Clinicians should be vigilant to find out the underlying causes of PIU, so as to obtain better therapeutic efficacy.Conclusion:We observed a rare disorder of PIU associated with SLE. Hence when identifying a patient of PIU, comprehensive evaluations and long-term follow-up are imperative to to detect the development of connective tissus diseases, such as SLE.

简介：AIMTo把主要、周期性的pterygium外科的长期的结果与三种不同技术作比较：联合结膜自体移植和覆盖羊膜的膜移植(有AMT的猫)，结膜自体移植移植(猫)独自一个、羊膜的膜移植(AMT)alone.METHODSIn这回顾的研究，142个pterygium病人的142只眼睛(104主要，38周期性)经历了猫(组A)，AMT(组B)或有AMT(组C)的猫分别地后面的外科的切除基于复发和手术后的complications.RESULTSThe数字被考察并且比较一样的描述在下面)，18(10，8)并且2(1，1)在组A，B，和C分别地；干燥眼睛是22(16，6)，27(18，9)并且7(3，4)；结膜发炎是30(17，13)，27(16，11)并且11(6，5)。在组C(主要或周期性的任何一个或两个)的病人主要在组A或B比那些显示出显著地更好的结果(P<0.05)关于上述临床的effects.CONCLUSIONCombined猫并且过分AMT比猫或AMT为主要、周期性的pterygium外科有复发和手术后的复杂并发症的显著地更低的率独自一个。
