目的：分析先天性泪腺皮肤瘘伴异位泪腺的临床表现，总结其治疗方案。方法：采用病例研究与文献回顾方法，记录1例确诊为先天性泪腺皮肤瘘伴异位泪腺患儿的外观照片、泪道探查冲洗情况、泪腺瘘管数字减影检查、泪腺瘘管CT造影检查等结果。予患者行泪腺瘘管下段及异位泪腺切除+泪腺瘘管上段转位结膜囊吻合代泪腺导管术，术中切除的病变组织行病理检查，术后随访。以“泪腺瘘”、“异位泪腺”为检索词，在 PubMed、CNKI 数据库中进行文献检索，检索到相关文献共 25 篇。结果：患儿为男性，5岁，眼科检查于左眼上睑中外1/3处见直径约1 mm瘘口，瘘口皮肤凹陷并有簇状毛发生长，有透明液体从瘘口阵发性流出。泪器检查示左上睑皮肤瘘管开口朝外上方，瘘管探查从瘘口进针，瘘管先是内下方走行再向外下走行，在距皮面3.5 mm处有一软性抵抗，加压不能突破，冲洗液原路反流，无脓液或血性液体反流。左眼泪腺瘘管数字减影检查示左眼泪腺瘘管造影剂存留，瘘管深部存在扇形腔隙。泪腺瘘管CT造影结果显示左眼外侧泪腺高密度影。术后随访6个月，患儿左眼上睑切口愈合好，未见瘘管复发，转位的泪腺瘘管成功将泪液引流入上穹隆结膜囊内。结论：先天性泪腺瘘同时合并先天性泪腺异位和毛发异位者临床上罕见，术前详细检查和精确诊断对指导治疗很有帮助；在明确主泪腺是正常的情况下，完整切除异位的泪腺组织，并行泪腺瘘管转位吻合于上穹隆结膜囊代泪腺导管术，是一种较好的治疗选择。

Objective: To demonstrate the clinical characteristics and surgical effects of congenital lacrimal gland cutaneous fistula with ectopic lacrimal gland. Methods: Observational case study and literature review. The results of appearance photographs, lacrimal duct probing and irrigation, digital subtraction imaging of the lacrimal fistula, and CT scanning of lacrimal fistula in a patient diagnosed with lacrimal gland cutaneous fistula with ectopic lacrimal gland were recorded. The surgical treatment for the patient was explored. The surgical strategy entailed resecting the lower segment of the lacrimal gland fistula and ectopic lacrimal gland, combined with transposing the upper segment of lacrimal gland fistula for conjunctival sac anastomosis, instead of using lacrimal gland catheter. Pathological examination and postoperative follow-up were conducted. Results: Ophthalmic examination revealed a fistula with a diameter of approximatedly 1 mm in medial-temporal 1/3 of the upper eyelid of the left eye. The skin surrounding the fistula was sunken and covered with tufts of hair. There was a paroxysmal discharge of clear fluid from the fistula. Lacrimal examination showed that the opening of the fistula on the skin of the left upper eyelid was directed outward and upward. Fistula exploration was conducted through the opening. The fistula tract initially coursed medially and caudally, then laterally and caudally. At a depth of 3.5mm from the dermal surface, a soft resistance was encountered that could not be overcome with forced pressure. The irrigation fluid refluxed along its original pathway, with no pus or bloody fluid regurgination. Digital subtraction imaging of the lacrimal fistula in the left eye demonstrated that contrast media remained and formed fanshaped spaces in the depth of the fistula. CT results of lacrimal fistula revealed a high density of lacrimal gland in left eye. During outpatient follow-up six months after surgery, the incision on the left upper eyelid was observed to have healed well, with no recurrence of the fistula The transposed lacrimal fistula successfully diverted tears into the conjunctival sac of the upper fornix. Conclusions: Congenital lacrimal gland cutaneous fistula combined with congenital ectopic lacrimal gland and ectopic hair is rare in clinical practice. Detailed preoperative examination and accurate diagnosis are extremely beneficial for guiding treatment. When the main lacrimal gland is normal, a better treatment choice involves completely removing the ectopic lacrimal gland tissue and transferring the lacrimal gland fistula to the conjunctival sac of the upper fornix to replace the lacrimal gland catheter.

目的：探讨爱先蓝(Alcian Blue，AB)和细胞角蛋白(cytokeratin，CK)双重染色技术在泪腺腺样囊性癌组织中的应用, 提高泪腺腺样囊性癌染色效率。方法：选取中山大学中山眼科中心临床病理科2015年1月至2017年1月期间诊断为泪腺腺样囊性癌病例标本23例，在同一张切片上先进行AB染色，再进行CK染色，观察染色效果。结果：23例泪腺腺样囊性癌标本组织中黏液物质全部呈蓝色；癌细胞胞质CK阳性，呈棕黄色。结论：AB和CK双重染色方法稳定，颜色对比鲜明，能够良好显示癌细胞及黏液的关系，并且比分开的两次单种染色省时、经济。

Objective: To investigate the application of Alcian Blue (AB) and cytokeratin (CK) double staining technique in adenoid cystic carcinoma to improve the staining efficiency. Methods: Twenty-three specimens of adenoid cystic carcinoma from January 2015 to January 2017 in the Clinical Pathology Department of Zhongshan Ophthalmic Center, Sun Yat-sen University were stained with AB first and CK then on the same slide. Results: Mucinous substance showed blue. And the cytoplasm of the cancer cells presented with brown yellow in all the specimens.Conclusion: The method of double staining with AB and CK is stable and displays bright color contrast. It can effectively reveal the relationship between the mucus and cancer cells. It proves to be more time-saving and economical than the individual staining of AB and CK respectively.

目的：研究雌二醇(estradiol，E2)和丙酸睾酮(testosterone propionate，TP)对兔泪腺上皮细胞凋亡及对MMP-9蛋白表达的影响，探讨雌二醇及丙酸睾酮对干眼的作用机制。方法：体外培养兔泪腺上皮细胞，分别给予雌二醇及丙酸睾酮处理，双氧水(H₂O₂)诱导细胞凋亡，流式细胞仪检测细胞凋亡和免疫细胞化学法检测细胞MMP-9蛋白表达。实验分4组：凋亡对照组(AC组)、雌二醇组(E2组)、丙酸睾酮组(TP组)和空白对照组(BC组)。AC组只给予H₂O₂诱导凋亡，E2组给予1×10^-5mol/L雌二醇处理，TP组给予丙酸睾酮处理，BC组未加药物干预及未加H2O2诱导凋亡。结果：经H₂O₂诱导细胞凋亡后，泪腺上皮细胞早期凋亡率和MMP-9蛋白表达累积光密度值与BC组相比，AC组、E2组及TP组均显著增加；同比AC组，E2组及TP组细胞凋亡率和MMP-9蛋白表达量降低；E2组凋亡率及蛋白表达量比TP组明显降低；其差异均具有统计学意义(P<0.01)。结论：雌二醇和丙酸睾酮对H₂O₂诱导兔泪腺上皮细胞凋亡有一定的抑制作用，同时泪腺上皮细胞中MMP-9表达含量也降低，提示雌二醇和丙酸睾酮抑制兔泪腺上皮细胞凋亡的作用机制可能与MMP-9有关。

Objective: To investigate the effects of estradiol (E2) and testosterone propionate (TP) on apoptosis and matrix metalloproteinase-9 (MMP-9) expression in rabbit lacrimal gland epithelial cells. Methods: The rabbit lacrimal gland epithelial cells were cultured in vitro. H₂O₂ was used to induce apoptosis in cultured lacrimal gland epithelial cells and then treated with E2 and TP respectively. Cell apoptosis was detected by flow cytometer (FCM) and MMP-9 expression was evaluated by immunocytochemistry. There were four groups: apoptosis control group (AC), estradiol group (E2), testosterone propionate group (TP) and blank control group (BC) respectively. The cells of group AC were administrated with H₂O₂ only, group E2 and group TP with 1×10^_5 mol/L E2 and TP respectively and group BC in treated. Statistical analysis were performed with one-way analysis of variance (ANOVA test)using SPSS 16.0, P<0.05 was considered statistically significant. Results: Compared with group BC, the early cells apoptosis rate and integrated optical density of MMP-9 expression of lacrimal gland in group AC, E2 and TP increased significantly after the cells were induced by H₂O₂; Compared with group AC, group E2 and TP reduced; group E2 were significantly lower than group TP; the differences were all statistically significant (P<0.01). Conclusion: E2 and TP had a certain inhibitory effect on rabbit lacrimal gland epithelial cells apoptosis induced by H₂O₂. Meanwhile, MMP-9 expression of the lacrimal gland cells was decreased. These results indicated that E2 and TP on the apoptosis inhibitory mechanism of lacrimal gland cells may be related with MMP-9. 

眼眶泪腺淋巴上皮癌是一种非常少见的恶性肿瘤。本例为一位46岁女性患者，表现为左眼睑红肿、眼球突出和视力下降，临床和影像学表现类似于泪腺炎型假瘤。手术完整切除后送检病理检查，其特征是未分化的癌巢之间有大量分化成熟的淋巴细胞、浆细胞浸润，确诊为淋巴上皮癌。术后行化学治疗和局部放射治疗，随访6.5年无复发。眼眶泪腺淋巴上皮癌的临床表现容易与泪腺炎型假瘤相混淆，应该进行病理学检查以明确其恶性表型，完整切除后辅助放化学治疗有较好的效果。

Lymphoepithelial carcinoma of the orbital lacrimal gland is a rare carcinoma. A 46-year-old female patient presented with red and swollen left eyelid, proptosis and blurred vision. The clinical and imaging manifestations were similar to inflammatory pseudotumor. Pathological examination was performed after complete resection.Pathological features showed undifferentiated carcinoma nests surrounded by obvious infiltration of non-neoplastic lymphocytes and plasma cells, which was consistent with the diagnosis of lymphoepithelial carcinoma.Chemotherapy and local radiotherapy were performed after the resection. The case did not relapse after 5 years of follow-up. The clinical manifestations of orbital lacrimal lymphoepithelial carcinoma were easily confused with inflammatory pseudotumor. Pathological examination should be performed to clarify its malignant phenotype.Adjuvant radiotherapy and chemotherapy after complete resection had a good effect.

Objective: To investigate the differences in bone destruction, nerve invasion, and prognosis of lacrimal gland adenoid cystic carcinoma (LGACC) among different histologic types and grades. Methods: A retrospective analysis was performed on 30 cases of lacrimal gland adenoid cystic carcinoma confirmed by histopathology who were admitted to the Department of Ophthalmic Oncology, Beijing Tongren Hospital, Capital Medical University from April 2010 to April 2019. The general data, imaging findings, histological examination and prognosis were collected and analyzed, with the focus on the relationship between the histological characteristics and the prognosis of lacrimal gland adenoid cystic carcinoma. Results: Among the 30 patients, 9 cases of cribriform type (30.0%); 10 cases of solid type (33.3%); 11 cases of mixed type (36.7%), including 4 cases of solid and glandular (13.3%), 4 cases of solid and cribriform (13.3%), 3 cases of cribriform and glandular (10.0%). The histopathological grade was I in 12 cases (40.0%), II in 4 cases (13.3%) and III in 14 cases (46.7%). There was statistical difference in the incidence of bone destruction among different histological types (P=0.046). There was no significant difference in the incidence of bone destruction among different histological grades (P=0.513).There was no significant difference between different histological grades and types and the incidence of nerve invasion and distant metastasis (all P>0.05). After surgery combined with radiotherapy, there was a statistical difference in the recurrence-free rate of different histological types, and the recurrence-free rate of solid type was the lowest within 36 months (P=0.037). Histological grade was not associated with recurrence-free rate after surgery combined with radiotherapy (P=0.059). Conclusion: The histological type of adenoid cystic carcinoma of lacrimal gland was significantly correlated with the incidence of bone destruction and recurrence rate, in which solid type was more likely to relapse. And the histological type was not associated with the incidence of nerve invasion or distant metastasis. Histopathological grade was not significantly associated with the rate of bone destruction, nerve invasion, distant metastasis, and recurrence.
