Abstract
AIMS Adenomas of the ciliary body epithelium, including adenoma of the pigmented ciliary body epithelium (APCE) and adenoma of the non-pigmented ciliary body epithelium (ANPCE), are extremely rare, and most knowledge about them comes from sporadic case reports. The purpose of this study was to provide a comprehensive understanding of adenomas of the ciliary body epithelium and to identify the similarities and differences between APCE and ANPCE. METHODS This study was a retrospective case series comprising data from 41 patients obtained from retrieved publications and five cases diagnosed at the Shanghai Ninth People's Hospital. The clinicopathological features, treatment and prognosis of APCE and ANPCE were compared using the non-parametric rank sum test, t-test and the χ2 test. RESULTS The clinical and histopathological features and treatment were analogous between APCE (n=23) and ANPCE (n=23). The overall visual prognosis associated with the two tumours was good, with 63% of the patients having stable or improved vision after treatment. Enucleation was the primary cause of eventual vision loss (three in APCE vs two in ANPCE, p=0.001). Notably, iris invasion was commonly observed in patients with APCE (six in APCE vs zero in ANPCE, p=0.014), and iris invasion was associated with decreased vision eventually (p=0.003). Tumour size was irrelevant to the vision outcome (p=0.65). Metastasis or recurrence did not occur in any of the patients. CONCLUSION In most cases, the clinicopathological features of ANPCE and APCE were similar. Iris invasion was commonly observed in patients with APCE, which was associated with poor visual prognosis.

Abstract
Purpose To report the unexpected finding of a membrane resembling a second anterior lens capsule during cataract surgery after previous pars plana vitrectomy (PPV) with silicone oil tamponade for retinal detachment. Observations A 26-year-old male with a history of two retinal detachment repairs of the right eye over a 5-month period, presented with decreased vision. The first retinal detachment repair was performed with a 23-gauge PPV and the second with a 25-gauge PPV, scleral buckle and placement of silicone oil. Additional ocular history includes bilateral megalocornea, high myopia, and temporal lens coloboma. Upon presentation, slit lamp exam showed migration of silicone oil to the anterior chamber and a nuclear cataract. A decision was made to perform combined silicone oil removal and cataract extraction with intraocular lens (IOL) implant of the right eye. After capsulorrhexis, hydrodissection of the lens was not completed successfully since the presence of a membrane was detected. This membrane was cut, achieving partial completion of the second capsulorrhexis, which was further advanced using a forceps following the contour of the first capsulorrhexis. The cataract was removed without further difficulty and the IOL was placed into the capsular bag with good centration. The membrane was submitted to pathology, and upon microscopic examination was found to represent fibrocellular tissue with some cells expressing PAX8 and cytokeratin AE1/AE3. Conclusions and importance This case reports the unusual finding of a membrane that behaved as a second anterior lens capsule intraoperatively and that expressed novel pathology markers. These findings may better prepare ophthalmologists for similar pathologies they may encounter during capsulorrhexis.

Abstract
BACKGROUND Deviations from the classic melanocytic immunophenotype in melanoma can present a diagnostic challenge. PAX8 and PAX2 are common markers for renal or Müllerian differentiation. While most PAX8+ or PAX2+ carcinomas are seldom confused with melanoma, some cases may show a more ambiguous immunophenotype, especially when MiTF family altered renal cell carcinoma (MiTF-RCC) is in the differential diagnosis. Neither PAX8 nor PAX2 expression has been reported in melanoma to date. We aimed to better characterize PAX8, PAX2, and cytokeratin immunoreactivity in a large series of melanomas. METHODS Tissue microarrays consisting of 263 melanomas were immunostained for PAX8, PAX2, and cytokeratin and graded by an h-score. RESULTS PAX8 expression was seen in 7.9% of melanomas and was significantly associated with spindle cytomorphology. PAX2 was positive in one (0.4%) melanoma. Cytokeratin positivity was seen in three (1.2%) cases and was associated with metastases. CONCLUSIONS PAX8 is expressed in a subset of melanomas and may be strong/extensive. As PAX8 positivity does not exclude a diagnosis of melanoma, it should be used in conjunction with other immunohistochemical markers, such as cytokeratin and PAX2, when melanoma, MiTF-RCC, and other PAX8+ tumors are in the differential diagnosis.

Abstract
Cancer is the second most common culprit of mortality in the United States and epithelial carcinomas are considered as one of the most predominant types of cancer. The association between epithelial cancers and paired-box gene 8 (PAX8) has been studied significantly before. PAX8 belongs to the paired-box gene family, which plays an important role in the organogenesis of different body organ systems, especially the thyroid gland, the renal system, and the Müllerian system. Immunohistochemical staining is being used to detect PAX8 expression in different epithelial cancers and differentiate them from PAX8-negative tumors. In follicular, papillary, and anaplastic thyroid carcinomas, targeting the PAX8/peroxisome proliferator-activated receptors (PPARs) fusion protein is being considered as a potential mechanism for therapy. Moreover, because of its high expression in primary ovarian cancers, PAX8 is being considered as a target for ovarian cancer treatment as well. More studies are needed to test the possibility of using PAX8 as a possible target for managing endometrial carcinomas. In this article, we review the functions of the PAX8 gene, how its mutations lead to the development of certain epithelial carcinomas, how it can be used as a diagnostic or a prognostic marker, and its potential as a therapeutic target for these cancers.
