Abstract
PURPOSE To determine the usefulness of melan-A, SOX10, HMB45, and p16 immunohistochemical stains in the distinction between the low-grade and high-grade conjunctival melanocytic intraepithelial lesions, either independently or as components of an immunohistochemical panel. DESIGN Retrospective observational case series. METHODS Institutional pathology records between 2014 and 2018 were searched for all patients with conjunctival melanocytic intraepithelial lesions. Biopsies without supporting clinical history or tissue available for review and immunohistochemical analysis were excluded. Clinical, histopathologic, and immunohistochemical (p16, SOX10, HMB45, and Ki-67) findings were recorded. RESULTS Thirty-one patients underwent 47 biopsies for conjunctival melanocytic lesions between 2014 and 2018. Pathologic diagnoses were low-grade conjunctival melanocytic intraepithelial lesion (n = 18, 38%) and high-grade conjunctival melanocytic intraepithelial lesion/melanoma in situ (n = 29, 62%). The addition of melan-A and SOX10 immunohistochemical stains resulted in an upgrade of conjunctival melanocytic intraepithelial lesion from low-grade to high-grade in 2 (4%) of 47 cases. The addition of melan-A and SOX10 immunohistochemical stains did not downgrade any of the histomorphologically high-grade lesions. In a clinical-pathologic multivariable model, the parameters most predictive of high-grade melanocytic intraepithelial lesion/melanoma in situ were involvement of the caruncle (odds ratio [OR] = 19, confidence interval [CI] 1.6-212; P = .02] and p16 cytoplasmic H-score >30 (OR = 81, CI 2.7 to >999; P = .01) CONCLUSION: Although the stains for melanocytic markers melan-A and SOX10 facilitate assessment of melanocytic intraepithelial lesions, the current immunohistochemical panels have limited value in distinction between the low-grade and high-grade intraepithelial melanocytic proliferations and need to be used judiciously.

Abstract
Purpose Conjunctival squamous cell carcinoma (SCC) is primarily treated with surgical resection. SCC has various stages, and local recurrence is common. The purpose of this study was to determine molecular localization of epidermal growth factor receptor (EGFR) and the possibility of EGFR as a biomarker for the management of conjunctival SCC. Methods In this retrospective study, we performed immunohistochemistry to evaluate EGFR expression and localization in tumor cells, EGFR mutation-specific expression (E746-A750del and L858R), and human papillomavirus expression in a series of 29 conjunctival SCCs. Results All 29 tumors in our cohort were EGFR positive (100%). Twenty-one of 29 tumors (72%) showed focal EGFR staining, and seven (28%) showed diffuse EGFR staining. In addition, we calculated the percentages of the two most important mutations in EGFR (exon 19 746-A750del (8/29, 27.5%), exon 21 (L858R mutant (2/29, 6.8%)) in conjunctival SCCs. We observed that the translocation of EGFR from the membrane into the cytoplasm was related to clinical prognosis, as we detected correlations between EGFR cytoplasmic staining and final orbital exenteration and between decreased EGFR membrane staining and progression-free survival. Conclusions EGFR is important in the pathology of ocular surface squamous neoplasia including SCC and is a prognostic factor. Increased understanding of EGFR mutations may have important implications for future treatment options.

Abstract
Purpose The aim of this study was to investigate HIF-1α, HIF-2α, and ProExC expression in conjunctival intraepithelial neoplasia (CIN), to differentiate between metaplasia and dysplasia, and to access their value as diagnostic and prognostic immunohistochemical markers. Recurrence and progression into SCC (squamous cell carcinoma) were defined as endpoints. Methods Forty-three specimens including CIN I (2), CIN II (9), CIN III (29), with and without metaplasia, and metaplasia alone (3), as well as 21 conjunctival control specimens, were stained with antibodies against HIF-1α, HIF-2α, and ProExC. The percentage of positively stained cells were calculated and used for further analysis. Results The mean percentages of HIF-1α and HIF-2α were not increased in CIN. In comparison, the expressions of these markers were even significantly elevated in control specimens (p < 0.001). Upper epithelial cells in CIN were more often ProExC-positive compared with normal conjunctiva or metaplasia (p = 0.06 and p = 0.07). Cox proportional-hazards analysis was performed for characterization of factors influencing the combined endpoint and showed a significant elevated hazard ratio for staining with ProExC (p = 0.04) compared with HIF-1α (p = 0.26) and HIF-2α (p = 0.49). Conclusion Our study shows that HIF-1α and HIF-2α do not serve as diagnostic or prognostic markers in CIN. ProExC seems to be a potential indicator for CIN, but not a reliable diagnostic marker. However, control specimens occasionally also display a high percentage of ProExC-positive cells and staining over the entire epithelial layer.

Abstract
The majority of ocular adnexal lymphomas are B-cell in origin. We report two cases of T-cell lymphoblastic lymphoma (T-LBL) involving the ocular adnexa. One patient presented with a painless pink conjunctival lesion and inferior orbital fullness. The second patient presented with a painless orbital mass. The diagnoses were confirmed by histopathology and immunohistochemistry. Both patients had extensive multifocal lesions during staging. Prompt intensified chemotherapy regimens were initiated. T-LBL is an aggressive disease with poor prognosis. This report emphasizes the importance of timely diagnosis by the ophthalmologist with co-management and treatment with an oncologist.

Abstract
PURPOSE To evaluate the clinical and pathologic characteristics of conjunctival myxoid lesions, with specific focus on PRKAR1A studies, in order to distinguish neoplastic conjunctival myxoma from other myxoid conjunctival lesions. METHODS A retrospective, interventional, multicenter study of all patients with conjunctival myxoma, conjunctival stromal tumor, or reactive fibromyxoid proliferation diagnosed during 1988-2018. Patient and family medical histories and clinical and pathologic characteristics of excised lesions were assessed. RESULTS There were 28 patients with conjunctival myxoid lesions diagnosed as myxoma (16/28), conjunctival stromal tumor (10/28), or reactive fibromyxoid proliferation (2/28). The patients with abundant myxoid matrix lesions (14/28, 50%) were younger (mean 49 [range 23-68] years) than those with scant-to-moderate myxoid matrix lesions (14/28, mean 61 [range 18-82] years; P = .04). Abundant myxoid matrix lesions more likely contained predominantly stellate cells (6/14 [43%] vs 0/14 [0%]; P = .05) and fibrillar collagen (13/14 [93%] vs 2/14 [14%]; P < .0001), conforming to the standard morphologic definition of myxoma. Absence of PRKAR1A protein expression was found in 2 lesions with morphologic features of myxoma (2/14, 14%), 1 of which demonstrated a pathogenic mutation in the PRKAR1A gene. There was no difference between the lesions with respect to other clinical and pathologic parameters. CONCLUSIONS PRKAR1A plays a role in the development of a subset of conjunctival myxomas, particularly in tumors fulfilling stringent morphologic criteria for myxoma. With the exception of PRKAR1A studies, current immunohistochemical panels cannot reliably distinguish between neoplastic conjunctival myxomas and other myxoid lesions, underscoring the importance of morphology in establishing accurate diagnosis.

Abstract
Malignant melanoma of the conjunctiva (CM) is an uncommon but potentially deadly disorder. Many malignancies show an increased activity of the epigenetic modifier enhancer of zeste homolog 2 (EZH2). We studied whether EZH2 is expressed in CM, and whether it may be a target for therapy in this malignancy. Immunohistochemical analysis showed that EZH2 protein expression was absent in normal conjunctival melanocytes and primary acquired melanosis, while EZH2 was highly expressed in 13 (50%) of 26 primary CM and seven (88%) of eight lymph node metastases. Increased expression was positively associated with tumour thickness (p =0.03). Next, we targeted EZH2 with specific inhibitors (GSK503 and UNC1999) or depleted EZH2 by stable shRNA knockdown in three primary CM cell lines. Both pharmacological and genetic inactivation of EZH2 inhibited cell growth and colony formation and influenced EZH2-mediated gene transcription and cell cycle profile in vitro. The tumour suppressor gene p21/CDKN1A was especially upregulated in CM cells after EZH2 knockdown in CM cells. Additionally, the potency of GSK503 against CM cells was monitored in zebrafish xenografts. GSK503 profoundly attenuated tumour growth in CM xenografts at a well-tolerated concentration. Our results indicate that elevated levels of EZH2 are relevant to CM tumourigenesis and progression, and that EZH2 may become a potential therapeutic target for patients with CM. © 2018 The Authors.

Abstract
We analysed by immunohistochemistry the expression of p53 protein in a case of micro-invasive carcinoma of the conjunctiva. About 50% of tumor cells showed a strong nuclear positivity for p53. This suggests that p53 gene alterations play a role in the development of this type of tumor.

Abstract
Conjunctival melanocytic lesions encompass a group of clinically diverse, benign to malignant, neoplasms that may contain overlapping histopathological features, making definitive diagnosis challenging in some cases. In this series, we compared multiple immunohistochemical (IHC) markers in 11 conjunctival nevi, 10 primary acquired melanosis (PAM) lesions, and 11 conjunctival melanomas. Immunostains included the melanocytic markers HMB-45 and Melan-A, as well as the proliferative marker Ki-67. Loss of beta-catenin expression has been associated with more aggressive clinical disease in cutaneous melanoma, but its status in conjunctival melanocytic lesions is not known, therefore we incorporated beta-catenin immunohistochemical staining in our study. In this series, conjunctival melanomas had a higher Ki-67 proliferative index and HMB-45 immunoreactivity than did PAM lesions and conjunctival nevi (P<0.001). Melan-A was highly expressed in all 3 groups. Beta-catenin was more strongly expressed in melanomas and nevi than in PAM (P<0.001). There was high inter-grader reliability (Kappa=0.53). Overall, IHC labeling of HMB-45 and Ki-67 is increased in conjunctival melanomas compared to PAM or conjunctival nevi. Beta-catenin, an IHC marker previously unstudied in conjunctival melanocytic lesions, is not preferentially expressed in benign lesions and may play a different role in conjunctival atypia than it does in cutaneous melanoma.

Abstract
Benign hemangiomas are rare vascular tumors of the conjunctiva that typically present clinically in the first few weeks of life and resolve spontaneously. De novo presentation later in childhood has not been well documented. We present the unusual case of an 11-year-old boy with a rapidly growing benign de novo conjunctival hemangioma that was treated with surgical excision.

Abstract
PURPOSE To review the diagnostic categories of a group of conditions referred to as "primary acquired melanosis." DESIGN Literature review on the subject and proposal of an alternative diagnostic schema with histopathologic and immunohistochemical illustrations. METHODS Standard hematoxylin-eosin-stained sections and immunohistochemical stains for MART-1, HMB-45, microphthalmia-associated transcription factor (MiTF), and Ki-67 for calculating the proliferation index are illustrated. RESULTS "Melanosis" is an inadequate and misleading term because it does not distinguish between conjunctival intraepithelial melanin overproduction ("hyperpigmentation") and intraepithelial melanocytic proliferation. It is recommended that "intraepithelial melanocytic proliferation" be adopted for histopathologic diagnosis. Atypical proliferations are characterized either by bloated dendritic melanocytes with enlarged cell components (dendrites, cell bodies, and nuclei) or by epithelioid melanocytes without dendrites. Atypical polygonal or epithelioid pagetoid cells may reach higher levels of the epithelium beyond the basal layer. Immunohistochemistry defines the degree of melanocytic proliferation or the cellular shape (dendritic or nondendritic) (MART-1, HMB-45) or identifies the melanocytic nuclei (MiTF). Intraepithelial melanocytic proliferation without atypia represents increased numbers of normal-appearing dendritic melanocytes (hyperplasia or early neoplasia) that generally remain confined to the basal/basement membrane region. Intraepithelial nonproliferative melanocytic pigmentation signifies the usually small number of conjunctival basal dendritic melanocytes that synthesize increased amounts of melanin that is transferred to surrounding keratinocytes. CONCLUSION All pre- and postoperative biopsies of flat conjunctival melanocytic disorders should be evaluated immunohistochemically if there is any question regarding atypicality. This should lead to a clearer microscopic descriptive diagnosis that is predicated on an analysis of the participating cell types and their architectural patterns. This approach is conducive to a better appreciation of features indicating when to intervene therapeutically. An accurate early diagnosis should forestall unnecessary later surgery.

Abstract
SWNHs induces accumulate with the levels of cytotoxic effects on different cell types and organs in animal models; it in a wide range may used for biomedical imaging. Conjunctival melanoma is a rare but potentially fatal ocular surface tumor. Recent studies of us have indicated the ability of SWNHs to inhibit proliferation of conjunctival melanoma cell line CRMM-1. But the role and molecular mechanisms of it was unclear. To address this question, the research about direct role of SWNHs on the growth, proliferation and apoptosis of CRMM-1 had been performed. Our results indicate that followed with the increasing concentrations of SWNHs, the number of cells decreased and apoptotic cells increased significantly. SWNHs delayed obviously mitotic entry of cells, and these effects followed the cultured time and the gradually increasing concentrations of SWNHs. SWNHs inhibited proliferation of cells at each time point in a time and dose-dependent manner, too. The TEM images showed that individual spherical SWNHs particles smaller than 100 nm in diameters were localized inside cytoplasma of cells. In summary, SWNHs inhibited mitotic entry, growth and proliferation of conjunctival melanoma cells and promoted its apoptosis, inhibited energy metabolism of cells in a dose-dependent manner. The roles of SWNHS on conjunctival melanoma cells were implicating energy metabolism. It may be the effective methods for treatment to conjunctival melanoma.

Abstract
A 63-year-old man presented with an asymptomatic papillary, sessile lesion of the juxtalimbal bulbar conjunctiva that was surgically excised with cryotherapy. Histopathologically, the lesion created some diagnostic confusion as it displayed an endophytic, or inverted, growth pattern-with squamous cells pushing into the substantia propria around fibrovascular cores, but without significant cytologic atypia, consistent with a conjunctival inverted papilloma (IP). Unlike previously reported cases of conjunctival IP, there were no goblet cells or cysts within the tumor. Immunostaining was diffusely positive for cytokeratin (CK) 7, and CK14 stained the basilar and suprabasilar cells, as in normal conjunctiva. CK17 weakly and non-uniformly stained the tumor, ruling out a dysplasia, which is usually strongly positive. The lesion's cytokeratin profile therefore paralleled that of normal conjunctiva. The proliferation index with Ki67 nuclear staining was extremely low (<1%), as was p53 nuclear staining (10-20%), both in contrast to squamous cell dysplasias or carcinomas that have a much higher percentage of positive cells. The lesion was negative for human papillomavirus subtypes associated with squamous neoplasias including carcinomas. We review the previous literature devoted to this comparatively rare condition and contrast its benign clinical course with that of inverted papillomas of the sinonasal, lacrimal drainage, and genitourinary systems and provide a set of criteria for establishing the diagnosis.

Abstract
PURPOSE To assess the role of androgen receptor detection in diagnosing eyelid sebaceous carcinomas and to compare it with that of adipophilin. DESIGN Retrospective, clinicopathologic study. METHODS Ten sebaceous carcinomas (8 invasive, 2 intraepithelial only) were stained immunohistochemically for androgen receptors and were compared with adipophilin staining. Receptor staining also was performed on benign sebaceous tumors (a sebaceoma and an adenoma) and as controls on eyelid basal cell carcinomas, eyelid squamous cell carcinomas, conjunctival squamous dysplasias, and conjunctival melanomas. RESULTS All 8 patients with an invasive component of sebaceous carcinoma underwent a biopsy in which the tumor cells showed diffusely positive results for androgen receptors (>20% of cells and usually >40%) and positive results for adipophilin. Eight cases displaying an intraepithelial (or pagetoid) component of spread also showed diffusely positive results for androgen receptors and adipophilin in at least 1 of multiple biopsy samples from each patient. However, in 8 of 21 separate conjunctival biopsy specimens with intraepithelial cytologic atypia, adipophilin results were negative. A sebaceoma and a sebaceous adenoma also showed positive results for both of these biomarkers. Among the controls, squamous carcinomas and melanomas showed negative results for androgen receptors and adipophilin. Basal cell carcinomas displayed focal receptor positivity in fewer than 5% of cells and showed negative results for adipophilin. CONCLUSIONS Androgen receptors and adipophilin can separate sebaceous tumors immunohistochemically from squamous carcinomas and melanomas, which showed negative results for both, and from basal cell carcinomas, which showed positive receptor results in a distant minority of cells. Regarding intraepithelial (or pagetoid) spread, androgen receptor detection was more sensitive and reliable than adipophilin in highlighting this component of the disease.

Abstract
PURPOSE To investigate the presence of KIT gene mutations and immunoreactivity in 85 conjunctival melanocytic tumours and to clarify the role of KIT as a potential therapeutic target in this group of patients. METHODS Eighty-five conjunctival pigmented tumours [27 melanomas, 12 primary acquired melanosis (PAMs) and 46 nevi] were immunostained for KIT. Intensity and pattern of expression were evaluated. Molecular analysis to identify KIT mutations was performed in 15 selected cases (tumour-rich areas >50%). KIT immunostaining score and pattern were statistically related to patients' age, sex, diagnostic category, presence of relapse, disease-free survival, presence of metastases, metastasis-free survival, limbal versus nonlimbal tumour location and thickness of melanomas. RESULTS KIT stains were documented in 48% of melanomas, 50% of PAMs and 24% of nevi. The mean score of KIT staining in the melanomas/PAMs group was significantly different from nevi (p = 0.0076). No statistically significant differences were detected between either c-kit immunostaining score or pattern and each of the other clinico-pathologic parameters considered. No KIT gene mutations were detected in melanomas and nevi. A silent mutation/polymorphism in KIT exon 13 was found in one PAM. CONCLUSIONS Despite the high level of KIT immunostains in PAMs and melanomas, this parameter seems not to be a good predictor of the presence of molecular mutations. KIT-activating mutations should be considered an uncommon event in this tumour.

Abstract
BACKGROUND Since it has been observed that melanocytic lesions can alter their appearance during pregnancy, we analyzed whether hormone receptors are expressed in conjunctival nevi as well as conjunctival melanoma. We further analyzed whether the number of estrogen (ER) or progesterone receptors (PR) might be associated with the disease course in conjunctival melanoma. METHODS Twenty-seven paraffin-embedded samples of conjunctival nevi and 27 conjunctival melanoma specimens were examined using immunohistological analysis with antibodies against PR and ER. The percentage of stained cells were analyzed, taking into account patient gender and age. Out of the melanoma group, all patients with complete data for tumor thickness, tumor localization, age at diagnosis, gender, and follow-up including recurrence, metastasis and tumor-related death were included in the second part of the study (n = 15), where hormone receptor rates were associated with tumor outcome, regarding recurrences, metastasis or death. Written consent was received from all included patients. RESULTS Both nevi and melanomas showed high rates of PR- and ER-positive cells. In Nevi, 64 ± 25 % of cells stained positive for PR and 35 ± 34 % for ER. In melanoma specimens, 68 ± 30 % showed PR and 44 ± 34 % ER expression. Differences between men and women in expression rates were not statistically significant. Out of 15 melanoma patients (nine female, six male), 53 % (five women and three men) experienced 1-4 recurrences, and four patients developed metastases. The median estimated survival time was 12.2 years. A multivariate survival model taking into account known risk factors for prognosis in conjunctival melanoma confirmed tumor location to be an important predictive factor for outcome (p = 0.05). The rate of PR or ER did not show a statistically significant correlation with the disease course in our cohort. CONCLUSIONS We observed that conjunctival melanocytic lesions express hormone receptors, which could explain why these tumors can alter their appearance under hormonal changes. Regarding the prognosis of conjunctival melanoma, no statistically significant correlation between hormone receptor expression and event-free survival was found in this analysis.

Abstract
AIM To examine the expression of αB-crystallin and vascular endothelial growth factor (VEGF) in conjunctival squamous cell carcinoma (CSCC). MATERIALS AND METHODS Seven CSCCs and three normal conjunctivas that were surgically excised were studied. Paraformaldehyde-fixed, paraffin-embedded tissue sections were processed for immunohistochemistry with antibodies against αB-crystallin, its phosphorylated forms, and VEGF. In vitro experiments were conducted to investigate the effects of mitomycin C (MMC) treatment on the expression of αB-crystallin and VEGF secretion. RESULTS αB-Crystallin and VEGF were strongly expressed in CSCCs compared to normal conjunctivas. αB-Crystallin immunoreactivity was co-localized with that for VEGF in CSCCs, whereas these signals were reduced in CSCC tissues treated with MMC before excision. MMC treatment suppressed the αB-crystallin expression and VEGF secretion in cultured conjunctival cells in a dose-dependent manner. CONCLUSION This study demonstrated αB-crystallin and VEGF expressions in human CSCCs, which may play a role in the pathogenesis. αB-Crystallin expression, and VEGF secretion were reduced by MMC, indicating a novel therapeutic mechanism in MMC treatment for human CSCC.

Abstract
Conjunctival melanoma is a relatively rare malignancy. It is presented as pigmented nodule in any area of conjunctiva, amelanotic tumors are pink with smooth appearance. The authors describe an amelanotic melanoma of the conjunctiva in an 82-year-old female patient. Cytological, histopathological and immunohistochemical studies revealed an invasive amelanotic melanoma exhibiting S-100 and MART-1 positivity. The patient undervent surgical and chemotherapy treatment and three years after the initial treatment is in the terminal stage of metastatic disease. Absence of pigmentation delayed early clinical detection and treatment. Awareness of this nonpigmented melanoma is crucial for early recognition and appropriate management.

Abstract
PURPOSE To characterize the differentiating histopathologic and immunophenotypic features of reactive lymphoid hyperplasia (RLH) and follicular lymphoma of the ocular adnexa. DESIGN Retrospective case study with clinical follow-up and review of the literature. METHODS Clinical records of 9 cases of RLH and 6 cases of follicular lymphoma from 2 institutions were reviewed. Light microscopic evaluation and immunohistochemical stains including CD20, CD3, CD5, CD21, CD23, BCL-2, BCL-6, CD10, kappa, lambda, and Ki67 were used to distinguish the 2 categories. RESULTS RLH preferentially involved the conjunctiva, whereas follicular lymphoma had a propensity to involve the lacrimal gland. Microscopic analysis with immunohistochemical staining distinguished RLH from follicular lymphoma. BCL-2 was positive in follicular centers of follicular lymphoma but not in RLH. CD10 identified follicular center cells and Ki67 quantified cells in S-phase. CD21 and CD23 detected dendritic cell scaffoldings of indistinct germinal centers. None of the patients with RLH developed lymphoma during their clinical courses (up to 18 years). However, 3 patients with orbital, but not conjunctival, RLH developed immunohistochemically proven multifocal nonophthalmic supradiaphragmatic adnexal RLH (sites included lung, parotid, axillary nodes, and uvea). All 6 patients with follicular lymphoma had disseminated disease. CONCLUSIONS A correct diagnosis of RLH vs follicular lymphoma can be reliably established employing immunohistochemical methods. A heretofore undescribed "multifocal RLH" syndrome must be distinguished from follicular lymphoma. Conjunctival RLH can usually be managed surgically without radiotherapy, but "multifocal RLH" required systemic treatment in 2 of 3 patients. Follicular lymphoma requires systemic chemotherapy if discovered beyond stage 1E.

Abstract
The authors report a localized (primary) conjunctival marginal zone B-cell lymphoma (mucosa-associated lymphoid tissue (MALT)-type), with amyloid deposition with relapse in the stomach, 14 months after the initial diagnosis. Ocular adnexal marginal zone B-cell MALT lymphoma is often localized at diagnosis; some relapse in typical MALT sites. There are few reports of localized conjunctival lymphoma with a relapse in the stomach. The authors suggest that all patients with localized ocular adnexal lymphoma be followed for an extended period.

Abstract
PURPOSE To examine the expression of glucose transporter protein-1 (GLUT-1) in ocular surface squamous neoplasia and to study its relationship with degree of neoplasia and cell proliferation index (Ki-67 labeling index). METHODS Twelve cases diagnosed as ocular surface squamous neoplasia (4 invasive and 8 intraepithelial tumors) at Inonu University Faculty of Medicine, Department of Pathology, were included in this study. There were 3 squamous cell carcinomas, 1 basosquamous cell carcinoma, and 8 conjunctival intraepithelial neoplasms. Immunohistochemically, GLUT-1 and Ki-67 antibody staining were performed. RESULTS GLUT-1 membranous immunoreactivity was seen in all tumors except in 1 case. GLUT-1 immunostaining was observed in all layers of the neoplastic epithelium of squamous cell carcinoma. Intense staining for GLUT-1 was determined in the upper two thirds of the severe dysplastic squamous epithelium. Although immunoreactivity for Ki-67 nuclear antigen was present throughout the epithelium, it was higher in the lower two thirds. Ki-67 labeling index ranged between 6% and 80%, and the mean value was 35% for invasive tumors and 20% for intraepithelial tumors. CONCLUSIONS Marked GLUT-1 and Ki-67 immunoreactive cells throughout the neoplastic epithelium of ocular surface squamous neoplasia were observed. In most cases, it was observed that GLUT-1 expression was severe in cases having >10% Ki-67 labeling index. These findings indicate that glucose uptake was increased in dysplastic cells, especially by GLUT-1. To our knowledge, this is the first study on the subject in the literature, and further studies with more cases are needed with GLUT-1 and other GLUT members.

Abstract
The aim of the study is to discuss the pattern and risk factors for metastatic disease in conjunctival melanoma. We draw comparisons with cutaneous metastatic melanoma. We describe the clinical course of a patient with recurrent conjunctival melanoma in the context of primary acquired melanosis with atypia. The local disease was eventually treated with a lid splitting exenteration. The patient suffered from an isolated distant metastasis to the gastric wall that was managed by partial gastrectomy. Conjunctival melanoma has many similarities with its cutaneous counterpart. In both conditions the regional lymph nodes are the most common site for metastases, however, isolated distant metastases can occur. Gastric metastases are frequently seen in cutaneous melanoma. This is the first report of an isolated gastric metastasis from a conjunctival melanoma.

Abstract
We studied the cases of 353 patients with lymphoma involving the ocular adnexa diagnosed at the Massachusetts General Hospital between 1974 and 2005. The patients included 153 males and 200 females, aged 7 to 95 years, with a mean age of 64 years. In 277 cases, there was no known history of lymphoma. Seventy-six patients had a history of lymphoma, with the ocular adnexa being involved at relapse or with progression of the previously diagnosed lymphoma. The patients had marginal zone lymphoma (182 cases), follicular lymphoma (80 cases), mantle cell lymphoma (18 cases), small lymphocytic lymphoma/chronic lymphocytic leukemia (13 cases), lymphoplasmacytic lymphoma (4 cases), splenic marginal zone lymphoma (2 cases), low-grade B cell, not subclassified (19 cases), precursor B lymphoblastic lymphoma (3 cases), diffuse large B-cell lymphoma (26 cases), and 1 case each of high-grade B-cell lymphoma, not subclassified, peripheral T-cell lymphoma, unspecified type, extranodal NK/T-cell lymphoma, nasal type, and Hodgkin lymphoma, nodular sclerosis type. Almost all marginal zone lymphoma patients (168 of 182, 92%) had primary ocular adnexal lymphoma. Fourteen marginal zone lymphoma patients (8%) had a prior history of lymphoma, usually arising in another extranodal site. Twenty-five of 80 (31%) follicular lymphoma patients had a prior history of lymphoma, usually arising in lymph nodes. Patients with mantle cell lymphoma, chronic lymphocytic leukemia, lymphoplasmacytic lymphoma, and splenic marginal zone lymphoma almost always had a prior history of lymphoma or were known to have widespread disease at the time of diagnosis of ocular adnexal lymphoma. A subset of the diffuse large B-cell lymphomas were associated with large destructive masses involving adjacent structures such as paranasal sinuses, raising the possibility that they may have arisen from one of the adjacent structures and involved the ocular adnexa by direct extension. The relatively high proportion of low-grade lymphoma, not subclassified, highlights the difficulty that may arise in distinguishing different types of low-grade lymphoma, particularly when biopsies are small and artifactually distorted. Ocular adnexal lymphoma is primarily a disease of older adults, with a slight female preponderance. Most lymphomas are low-grade B-cell lymphomas, with marginal zone lymphoma being by far the most common type. Marginal zone lymphoma typically involves the ocular adnexa primarily, whereas other types of low-grade B-cell lymphoma often involve the ocular adnexa secondarily. High-grade B-cell lymphomas only occasionally involve the ocular adnexa, and T-cell lymphoma, NK-cell lymphoma, and Hodgkin lymphoma are only rarely encountered in this site.

Abstract
BACKGROUND Conjunctival melanoma is a rare occurrence in the Negroid race. PURPOSE To report a case of a 55 year old security man with right conjunctival melanoma. METHOD A 55 old man was operated on to remove a pigmented right bulbar conjuctival growth. The specimen was submitted to Lagos University Teaching Hospital Lagos and Harold Wood Hospital England for histopathologic examination and confirmation. RESULTS Surgery was successful and histopathologic and immunohistochemical studies confirmed a diagnosis of a nodular malignant melanoma. CONCLUSION The need for the provision of definitive investigative tool (immunohistochemical studies) to facilitate definitive diagnosis and management of such cases in some recognised centres in Nigeria cannot be overemphasised.

Abstract
PURPOSE To describe a case of conjunctival malignant melanoma associated with pseudomelanomatous alteration of the apposing tarsal conjunctiva. METHODS A 93-year-old woman presented with an elevated, pigmented mass on her superior bulbar conjunctiva. The tumor was associated with increased pigmentation of the apposing superior tarsal conjunctiva. An excisional biopsy of the epibulbar melanoma and pigmented tarsal conjunctiva was performed. RESULTS Histopathologic evaluation of the epibulbar tumor revealed epithelioid melanocytes diagnostic of malignant melanoma. Histopathologic evaluation of the pigmented tarsal lesion showed large areas of ulceration and foci of granulation tissue composed of neovascular sprouts arising in the background of a loose connective tissue, with a moderate chronic inflammatory infiltrate. The infiltrate was composed of mature lymphocytes, plasma cells, and scattered histiocytes. Densely packed intracytoplasmic, brown pigment granules that stained positive with HMB 45 were found, attesting to adjacent melanocytes' releasing melanin-laden granules. There was no evidence of malignancy in the pigmented tarsal specimen. CONCLUSION Noncontiguous pigmented conjunctival tumor can be found in apposition to an epibulbar melanoma. Although a limited biopsy could be considered, only a complete resection and histopathologic evaluation can determine whether the entire lesion is free of malignant melanoma.

Abstract
PURPOSE To determine whether the tyrosine kinase epidermal growth factor receptor (EGFR) is expressed in squamous cell carcinoma of the conjunctiva. METHODS A retrospective, observational case series of 5 patients with biopsy-proven conjunctival squamous cell carcinoma treated at one institution between January 1996 and April 2004. Medical records and tissue specimens from the 5 patients were reviewed. A control specimen of normal conjunctiva was also obtained from one of the 5 patients. Immunohistochemical analysis was performed using antibodies against EGFR. RESULTS Immunohistochemical staining showed that EGFR expression was moderate to strong in all tissue specimens, both in the normal mucosa and in the in situ and invasive components of the conjunctival squamous cell carcinomas. CONCLUSIONS An intense expression of EGFR occurs in squamous cell carcinoma of the conjunctiva. Further study is needed to determine whether an EGFR inhibitor that targets this expression would have potential therapeutic benefit in treating squamous cell carcinoma of the conjunctiva.

Abstract
Fibrous histiocytomas are mesenchymal tumours composed of cells with fibroblastic to histiocytic differentiation. They can occur in any part of the body including the orbital tissues. To date, there are 18 cases of fibrous histiocytoma arising from the corneoscleral limbus reported in the literature. Eleven of these were classified as benign, and the rest were malignant fibrous histiocytomas. Benign fibrous histiocytomas have been reported in the orbit, eyelid, episclera and conjunctiva. Malignant fibrous histiocytoma has been well described in the orbit, but rarely as a primary conjunctival tumour. The rarity of the tumour makes its diagnosis and management a challenge. Herein, the clinicopathological features of a case of malignant fibrous histiocytoma are presented and its management with wide excision and cryotherapy followed by ocular reconstruction with amniotic membrane transplant is discussed.

Abstract
AIM To summarise the main causes and associations of conjunctival intraepithelial neoplasia (CIN) found in the literature to date. METHOD Literature search using Ovid databases on the NHS Scotland E-library, Medline, and the Cochrane Library. The internet search engine Google Scholar was also used to identify relevant articles. RESULTS The main causes and associations of CIN in the literature are sun exposure and distance from the equator; human papillomavirus infection, increased p53 expression, and HIV seropositivity. It has been found that in HIV positive individuals CIN is on the increase with people being affected with more aggressive tumours at younger ages. CONCLUSION Given that CIN is becoming more common in HIV infected populations and that it has the potential to cause severe disability, it is important to improve our understanding of the condition. Early identification of CIN by an understanding of its aetiology and associations may enable the implementation of preventative measures to reduce its incidence and potentially lead to the diagnosis and further management of conditions such as HIV. Young people presenting with CIN in particular may benefit from HIV testing.

Abstract
Squamous cell carcinoma (SCC), the most common primary malignant tumor of the conjunctiva, has a variable clinical presentation and immunohistochemical profile. Abundant cell cycles exist, including MIB-1 (Ki67 antigen), p16, p53, and p63, within the conjunctiva SCC. This investigation first reports the expressions of cell cycle markers in SCC. A retrospective study was conducted between December 1976 and June 2004, comprising 13 consecutive patients with conjunctiva SCC who were treated with surgical excision. Detailed clinical parameters were also reviewed. Overexpression of MIB-1, p16, p53, and p63 genes were studied by immunohistochemistry. Genechip containing 39 subtypes was used to elucidate human papillomavirus (HPV). The study group contained 13 (100%) men, with a mean age of 68+/-18 years and follow-up period of 20+/-17 months. The sample included four (33%) SCC located in the left eye and two (17%) recurrent SCC. Overexpression of the p53 and p63 was considerably higher than that of the p16 (P<0.01). HPV DNA was not detected in any of the 13 cases. This work first examined the immunohistochemical overexpression of cell cycle (MIB-1, p16, p53, and p63) in SCC. This investigation then showed that the expression of cell cycles in SCC was associated with key tumor clinicopathological features. This approach can help distinguish the potential roles of cell cycle in the development of SCC.

Abstract
BACKGROUND Virotherapy represents a novel therapeutic modality for the treatment of malignant diseases. Vesicular stomatitis virus (VSV) has been shown to exert antitumor effect in several tumor types. Since the potential oncolytic activity of VSV has not yet been evaluated in epithelial tumors of the conjunctiva, we set out to investigate the susceptibility of the immortalized Wong-Kilbourne derivative of the Chang conjunctival cell line (WK) to VSV and analyze the role of apoptosis in VSV-mediated induction of cell death. METHODS WK cells were infected with VSV at various multiplicities and maintained for different periods of time. VSV-infected cells were analyzed by inverted microscopy for the development of cytopathic effects (CPE). Virus replication was measured by indirect immunofluorescence assay, Western blot analysis and plaque titration. The apoptotic response of the infected cells was quantitated by ELISA detecting the enrichment of nucleosomes in the cytoplasm. Western blot analysis was used to determine the levels of Bcl-2 and Bax proteins. RESULTS The WK cell line was highly permissive to VSV replication and was highly susceptible for the CPE of this virus. VSV infection elicited the apoptotic death of WK cells. Mock-infected cells exhibited endogenous expression of Bcl-2 and p21 Bax proteins. VSV infection caused a significant decrease in the expression level of Bcl-2. Moreover, in parallel with a slight decrease in the level of p21 Bax, p18 Bax protein accumulated in VSV-infected WK cells. CONCLUSIONS VSV is a powerful inducer of apoptosis in immortalized WK cells. The VSV-mediated alterations in the expressions of Bcl-2 and Bax proteins may play important roles in the apoptotic responses of infected cells and may also sensitize to other apoptotic stimuli. This virus may possess oncolytic activity in epithelial tumors of the conjunctiva.

Abstract
PURPOSE To study BCL10 expression in ocular adnexal lymphoma in the US population and its association with clinical outcomes. DESIGN Institutional, retrospective study. METHODS Immunohistochemistry was performed with antibody against BCL10 on two tissue microarray blocks that were constructed with paraffin-embedded tissues from the same cohort of 48 patients with ocular adnexal lymphomas. The main outcomes that were measured include extraorbital involvement, recurrence rate, and time to recurrence. The median length of the follow-up period was 40 months. RESULTS Aberrant BCL10 expression (nuclear [moderate intensity] and cytoplasmic [weak to moderate intensity] staining) was observed in 10 of 33 cases (30.3%) of mucosa-associated lymphoid tissue (MALT) lymphoma, in 4 of 10 cases (40%) of follicular lymphoma (grade 1, 9 cases; grade 2, 1 case), in 0 of 2 cases of diffused large B-cell lymphoma, in 0 of 1 case of chronic lymphocytic leukemia/small lymphocytic lymphoma and in 1 of 1 case (100%) of mantle cell lymphoma. There were no differences in clinical parameters at examination (ie, average age, gender, site of occurrence, laterality, extraorbital involvement at diagnosis), recurrence rate, and time to recurrence for patients (MALT lymphoma or follicular lymphoma) with or without aberrant nuclear BCL10 expression. CONCLUSION Aberrant BCL10 expression can occur in other types of ocular adnexal lymphomas besides MALT lymphoma. Ocular adnexal MALT lymphoma may have slightly lower frequency of aberrant BCL10 expression than gastric/pulmonary MALT lymphomas that have been reported in the literature. Furthermore, aberrant BCL10 nuclear expression in ocular adnexal lymphoma does not seem to correlate with clinical outcome. Further studies that include a larger number of cases and longer follow-up period are needed to confirm our observation.

Abstract
Human papilloma virus (HPV) infection and loss of P53 function have been identified as frequent events in various human tumors. The aim of this study was to evaluate P53 protein expression and to detect HPV in the tissue samples of 45 benign (papillomas) and 38 malignant conjunctival and eyelid lesions (27 basal cell carcinomas and 11 squamous cell carcinomas). We also looked for eventual relationships between P53 expression and clinicopathological features such as age, histological type of tumor, grading and staging. HPV infection was detected using the PCR-RFLP method. Specific primers were engaged and PCR products of HPV 16, 18, and 33, underwent enzymatic digestion at 37 degrees C. We revealed P53 protein expression in 30 out of 45 (66.6%) squamous cell papillomas. In the SCC and BCC groups, P53 was present in 31 out of 38 carcinomas and there was a statistically significant correlation between histological type of tumor and P53 protein expression. Malignant type HPV 16 and 18 were detected in three squamous cell papillomas, two BCCs and one SCC. However, we observed P53 protein expression in only two HPV-positive papillomas and one infiltrative type of BCC. P53 is probably involved in the development of conjunctival and eyelid tumors due to its high rate of presence in both benign and malignant neoplasms of these organs. HPV seems to occur rarely. In some cases its role in the pathogenesis of conjunctival and eyelid tumorigenesis should be considered as auxiliary.

Abstract
PURPOSE The homeostatic chemokine, B cell attracting chemokine 1 (CXCL13), has been implicated in the pathogenesis of lymphocyte-mediated diseases. We investigated the cellular expression of this chemokine in the spectrum of ocular adnexal lymphoproliferative lesions. DESIGN Laboratory investigation. METHODS CXCL13 expression in paraffin-embedded adnexal biopsy specimens was determined by indirect immunohistochemistry with antigen retrieval. RESULTS In 15 of 16 biopsy specimens, including reactive lymphoid hyperplasia (n = 7), atypical lymphoid hyperplasia (n = 3), and B cell lymphoma (n = 6), CXCL13 was detected. CD20-positive B-cells, as well as dendritic cells and endothelial cells, expressed the chemokine. CONCLUSIONS B-cells in ocular adnexal lymphoproliferative lesions demonstrate expression of CXCL13, a chemokine that may participate in tumor pathogenesis and is a potential target for novel therapies.

Abstract
BACKGROUND p63 is a homologue of the tumour suppressor gene p53, which is expressed in human basal squamous epithelium. Some investigators maintain that p63 plays a role in the development of squamous epithelium and, despite its homology to p53, it is considered to act as an oncogene. This study investigated the expression of p63 in conjunctival intraepithelial neoplasia of different grades, and conjunctival squamous cell carcinoma and its correlation to the proliferation marker MIB-1. MATERIAL AND METHODS Seventeen conjunctival specimens excised with the suspicion of either conjunctival intraepithelial neoplasia (CIN) or squamous cell carcinoma were diagnosed histologically as follows: 2 squamous cell carcinomas of the conjunctiva, 2 CIN grade I, 3 CIN grade II, 7 CIN grade III, 2 CIN with beginning invasion and 1 normal conjunctiva with no dysplasia. Sixteen microscopically-normal postmortem conjunctival specimens and normal conjunctiva, CIN and carcinoma specimens were stained immunohistochemically with antibodies against p63 and MIB-1. At least 500 cells per specimen were counted and the percentage of positively-stained cells of each antibody was calculated. RESULTS A mean of 80% (57-89%) of the dysplastic cells from the CIN specimens stained positively with antibodies against p63, especially in the lower two-thirds of the epithelium, statistically significantly more compared with the normal specimens (9-55%, mean 36%, p<0.001). Nevertheless, we did not find a correlation between the percentage of p63-positive cells and the differentiation grade of the malignant specimens. MIB-1 positivity was shown by 0-1% of the cells in the normal postmortem controls, by 3-30% (mean 12%) of the cells in the basal and occasionally in the middle layer of the CIN specimens, and 16-61% (mean 23%) in the carcinoma specimens. CONCLUSION In conjunctival intraepithelial neoplasia and squamous cell carcinoma of the conjunctiva, p63 is preferentially expressed in the immature dysplastic epithelial cells. Its staining does not correlate with MIB-1-expression, and therefore does not appear to be linked to cell proliferation.

Abstract
BACKGROUND Both dermal and ocular melanocytic nevi have been reported to undergo changes during pregnancy. This has been proposed to be related to hormonal influences; however, few studies have provided any proof. We therefore set out to evaluate the expression of sex hormone receptors and cell cycle proteins in melanocytic lesions of the ocular conjunctiva. METHODS Formalin-fixed, paraffin-embedded material from 76 tumors--69 conjunctival nevi, 5 specimens of primary acquired melanosis (PAM), and 2 conjunctival melanomas--were included in a tissue microarray (TMA) format. The TMA sections were analyzed by immunohistochemistry with antibodies for progesterone and estrogen receptors, and cell cycle-related proteins (p16, MIB1-Ki67). RESULTS Progesterone receptors were highly (96%) and similarly expressed in all lesions. In addition, progesterone receptor expression showed a tendency to increase with age (p=0.06). In contrast, estrogen receptor expression was completely absent in all tumors. The cell cycle regulator p16 was expressed in 97% of the lesions. The proliferation marker MIB1-Ki67 was expressed at low levels (mean+/-SD: 13+/-14%) in 79% of the lesions. No differences of expression were found between the different lesions and nevi types. The mean age of the patients was highest in conjunctival melanoma (70+/-22 years), followed by PAM (60+/-19 years) and nevi (36+/-18 SD years). The different types of nevi also showed significant age dependency (junctional 25+/-17 years, compound 34+/-17 years, dermal 49+/-15 years). CONCLUSION Our findings reveal the expression of progesterone, but not estrogen, in melanocytic lesions of the ocular conjunctiva. In benign conjunctival lesions, p16 and MIB1-Ki67 expression was comparable to that in benign nevi of the skin.

Abstract
PURPOSE Malignant transformation of cells is frequently associated with abnormalities in HLA expression. These abnormalities may play a significant role in the clinical course of the disease because the cellular immune response to tumors relies on concomitant recognition of tumor antigens with self-HLA molecules. Since HLA molecules mediate interactions of tumor cells with specific receptors on T and natural killer (NK) cells, tight control of expression of HLA molecules is critical for initiation and implementation of an effective cellular immune response. There is not much information on HLA class I antigens in conjunctival carcinomas. We studied the immunoexpression of HLA class I antigen and beta2-microglobulin (beta2-m) in conjunctival dysplasias and conjunctival squamous cell carcinomas. METHODS HLA class I antigen and beta2-m expression were analyzed in 10 conjunctival dysplasias, 6 carcinomas in situ, and in 11 conjunctival carcinomas by immunoperoxidase staining with monoclonal antibodies to HLA class I antigen and beta2-m on the archival clinical samples. Immunoanalysis was done according to the International Histocompatibility Working Group Project Description. RESULTS HLA class I antigen and beta2-m were heterogeneous in 10 conjunctival dysplasias, negative in 6 carcinomas in situ, and 11 conjunctival squamous cell carcinomas. The difference of immunoexpression for HLA class I and beta2-m among the 3 groups was statistically significant (P <0.001). CONCLUSIONS HLA class I antigens and beta2-m are decreased in conjunctival dysplasias and negative in carcinomas in situ, and carcinomas. The findings support the role of cytotoxic T lymphocyte-mediated control of tumor growth in the clinical course of conjunctival squamous cell carcinomas.

Abstract
Cell proliferation and programmed cell death are considered to be important events in carcinogenesis. The object of our study was to evaluate the expression of the Bcl-2 protein family (Bcl-2, Bak, Bax), p53, proliferating cell nuclear antigen (PCNA), and Ki-67 protein immunoexpression as well as the correlation between the examined markers and some clinicopathological features in papillomas and cancers of conjunctiva and eyelid. Forty-five squamous cell papillomas (SCP), 11 squamous cell cancers (SCC), and 27 basal cell cancers (BCC) were estimated. In the SCP group, p53 protein expression was observed in 30 cases (66.6%), Ki-67 in 14 (31.1%), PCNA in 44 (97.8%), Bcl-2 in 24 (53.3%), Bak in 28 (62.2%), Bax in 31 (68.9%), and Bcl-xl in 11 (100%). In the SCC group, p53 protein expression was evaluated in 8 cases (72.8%), Ki-67 in 2 (18.2%), PCNA in 8 (72.7%), Bcl-2 in 5 (45.4%), Bax and Bak both in 10 (90.9%), and Bcl-xl in 100%. In the BCC group, p53 protein expression was estimated in 23 cases (85.1%), Ki-67 in 13 (48.1%), PCNA in 26 (96.2%), Bcl-2 in 13 (48.1%), Bak in 21 (77.8%), Bax in 22 (81.5%), and Bcl-xl in 23 (85.2%). We observed a correlation between some clinicopathological features and the examined markers of apoptosis and cell proliferation, which seemed to be important events in cancer development.

Abstract
PURPOSE To evaluate the relationships among histopathological type, clinical malignant grade, and Ki-67 labeling index (LI) in sebaceous gland carcinoma (SGC), conjunctival squamous cell carcinoma (SCC), and conjunctival intraepithelial neoplasia (CIN), with pterygium and normal conjunctiva as controls. METHODS This retrospective study was conducted at the Department of Ophthalmology, Kyoto Prefectural University of Medicine, Kyoto, Japan. We used tissue specimens obtained from 20 patients (four SGC, four SCC, four CIN, four pterygium, and four normal conjunctiva). Ki-67 immunohistochemical analysis was performed in all 20 cases. RESULTS The Ki-67 labeling index (LI) was 46.1 +/- 3.0% (average +/- SD) in SGC, 28.4 +/- 4.5% in SCC, 20.0 +/- 7.2% in CIN, 9.0 +/- 2.2% in pterygium, and 6.8 +/- 2.3% in normal conjunctiva. Ki-67 LI was significantly (Mann-Whitney U test, P < 0.05) higher in SGC than in SCC, and higher, but not significantly, in SCC than in CIN. Ki-67 LI was significantly (P < 0.05) higher in SCC and CIN than in pterygium. CONCLUSIONS These results suggest that Ki-67 LI may be a sensitive marker for ocular malignant tumor grading.

Abstract
AIM Very little is known about the immunology of conjunctival melanoma. We investigated the expression of cell adhesion molecules and the grade of tumour infiltration with lymphocytes and macrophages as important members for the communication between tumour cells and the immune system. METHODS Archival material from 35 conjunctival melanomas was used for immunohistochemical detection of intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), neural cell adhesion molecule (NCAM), CD3 and CD68 using monoclonal antibodies. Histological and clinical data for these tumours were assessed. RESULTS ICAM-1 was expressed in 34 of 35 tumours; in 20 cases, more than 50% of the cells stained ICAM-1 positive. VCAM-1 was expressed in 21 of 34 tumours; in 17 cases, only a small proportion (1-25%) stained VCAM-1 positive. NCAM was expressed in 14 of 34 tumours; in 11 cases, only a small proportion (1-25%) stained NCAM positive. CD3-positive leucocytes were found in 26 of 32 tumours, whereas CD68-positive leucocytes were present in 33 of 34 tumours. Cox regression analysis revealed that patients with NCAM-positive tumours had a 6.4-fold higher risk of dying from conjunctival melanoma (P = 0.02). NCAM-positive tumours were preferentially (P = 0.03) located in prognostically 'unfavourable' areas (i.e. fornices, palpebral, caruncle) and had no or only a weak CD3-positive infiltrate (P = 0.03). CONCLUSIONS ICAM-1, VCAM-1 and NCAM are differentially expressed in conjunctival melanoma. Leucocytes were present in almost every tumour. The association between NCAM expression and prognosis may be related to the differential anatomical tumour location of NCAM-positive and NCAM-negative tumours, and should be considered a preliminary observation due to the limited statistical power of this study.

Abstract
The aim of our study was an evaluation of the expression of cell proliferation markers (PCNA and Ki-67) in conjunctival and eyelid papillomas and squamous and basal cell cancers. A series of 9 cases of squamous cell cancer (SCC), 15 cases of basal cell cancer (BCC) and 43 cases of squamous cell papilloma (SCP) were assessed using the immunohistochemical method with monoclonal antibodies. PCNA overexpression was observed in 100% of SCP, in 88.8% of SCC and in 100% of BCC cases. Ki-67 overexpression was seen in 32.5% of cases of SCP, in 22.2% of SCC and in 66.6% of BCC. The results showed that an evaluation of Ki-67 expression is the most valuable cell proliferation marker.

Abstract
Marginal zone lymphoma of the mucosa-associated lymphoid tissue (MALT) occurring in the conjunctiva has yet not been described in pediatric patients. We present a case of a 10-year-old girl with a MALT lymphoma involving the conjunctiva. The tumor consisted of plasma cells and marginal zone cells with discrete epitheliotropism. Immunohistochemical studies revealed positivity for CD20 and cytoplasmic immunoglobulin lambda light chain restriction. Polymerase chain reaction-based molecular analysis of the infiltrate showed a monoclonal rearrangement for the hypervariable complimentary determining region III immunoglobulin region; whereas, a polyclonal pattern was seen for the T-cell receptor gamma chain. Extensive further examination, including molecular techniques, revealed that the lymphoma was restricted to the conjunctiva (stage IA) and was not associated with any specific infection. The patient was treated with surgery and additional local cryotherapy. After 15 months of follow-up, the patient remains in complete remission.

Abstract
PURPOSE To report a patient who was diagnosed with combined adult inclusion conjunctivitis (AIC) and mucosa-associated lymphoid tissue (MALT) lymphoma. METHODS This is a case report. RESULTS An 18-year-old male patient presented with chronic conjunctivitis and giant follicles. Evaluation by chlamydial antigen assay was positive. Conjunctival biopsy for the immunohistochemical stain and polymerase chain reaction of the left eye showed MALT lymphoma. CONCLUSIONS MALT lymphoma can masquerade as other ocular surface diseases. Chlamydial infection causes chronic inflammation of the conjunctiva. Both of these diseases should be considered as a differential diagnosis of refractory follicular conjunctivitis. It is worthy of further study to determine whether chronic inflammation resulting from chlamydial infection increases the risk of MALT lymphoma or it is coincidental.

Abstract
BACKGROUND To determine the prognostic value of cell-cycle associated markers in ocular adnexal lymphoma (OAL). METHODS Two hundred sixty-one consecutive cases of ocular adnexal lymphoproliferative lesions were subdivided into reactive lymphoid hyperplasia (RLH), atypical lymphoid hyperplasia (ALH) and OAL. The latter were sub-typed according to the new WHO Lymphoma Classification. All lesions were investigated applying standard immunohistochemical methods with antibodies specific for pRB, p53, p16, p21, BCL-6 and for multiple myeloma oncogene-1-protein (MUM1, also known as IRF4). The main endpoints included the development of a local recurrence, of systemic disease and of lymphoma-related death. The association of prognostic variables with endpoints was assessed by multiple logistic and Cox regression models, respectively. RESULTS The ocular adnexal lymphoproliferative lesions were categorised as OAL ( n=230; 88%), RLH ( n=29; 11%), and ALH ( n=2; 1%). The major lymphoma subtypes included 136 extranodal marginal zone B-cell lymphoma (EMZL), 31 diffuse large cell B-cell lymphomas, 27 follicular lymphomas, 9 plasmacytomas, 9 lymphoplasmocytic lymphoma/immunocytomas and 8 mantle cell lymphomas. The median follow-up time was 44.5 months. Most OAL patients had Stage IE disease and were treated with radiotherapy. Thirty-seven (25%) Stage IE patients had tumour relapses: these were significantly associated with an increased BCL6 blast percentage. Sixty-two (42%) Stage IE patients developed systemic disease: they had "non-EMZL" with large growth fractions and increased blast percentages for BCL6. Fifty-seven (25%) OAL patients died because of their lymphoma; lymphoma-related death was significantly associated on multivariable analysis with advanced clinical stage, an age >60 years and large tumour growth fractions. CONCLUSION Subtyping of OAL according to the new WHO Lymphoma Classification, the stage of disease and tumour cell growth fraction aided the prediction of (1) tumour relapse, (2) the development of systemic disease and (3) lymphoma-related death in OAL.
