ABSTRACT
Primary cutaneous mucinous carcinoma (PCMC) is a rare low-grade malignant neoplasm derived from the eccrine glands. PCMC most commonly arises in the head and neck, with the eyelid being the most common site of origin. This case report describes a 51-year-old male with a painless, pigmented superficial nodular lesion over his right lower eyelid. The lesion was considered to be benign, and the initial treatment was simple excision with a 3-mm margin. However, histologic examination revealed the diagnosis of PCMC, and the patient underwent re-excision of the tumor site with an additional 3-mm margin from the initial scar. Histologic study of this second margin was free of any malignant cells. The patient experienced no postoperative complication or recurrence after 2 years. In our case, the skin lesion had benign morphologic findings and was strongly suspected to be a benign mass. Physicians should be aware of this tumor and be able to differentiate it from benign cystic or solid eyelid lesions.

ABSTRACT Introduction: Stromal cells interact with tumor cells and play an important role in cancer invasion and metastasis. Tumor-associated macrophages (TAMs) can exhibit M1 phenotype, important immune effector cells, or M2 phenotype, able to suppress the function of M1 macrophages and influence angiogenesis and tissue repair. The CD68 antibody recognizes M1 and M2 macrophages, whereas CD163 antibody is specific only to identify M2 macrophages. Objective: To investigate the presence of TAMs in a number of cases squamous cell carcinoma (SCC) of the tongue by associating it with the occurrence of metastasis. Material and methods: Immunohistochemistry was used to evaluate the immunopositivity for CD68 and CD163 in 27 cases of SCC of the tongue. Results: The percentage of CD68 positive macrophages was higher than CD163 positive macrophages in all specimens studied. Comparing CD163 and CD68 immunostaining in the studied groups, it was observed that cases without metastasis had a higher percentage of CD68 positive cells in relation to CD163 positive cells, which was statistically significant. Conclusion: Considering these results, there was a predominance of M1 macrophages in SCC of the tongue cases without metastasis, suggesting the influence of these cells in clinical behavior of the lesion.
RESUMO Introdução: As células do estroma interagem com as células neoplásicas e desempenham papel importante na invasão e na metástase do câncer. Os macrófagos associados ao tumor (TAMs) podem se apresentar com fenótipo M1, importantes células efetoras, ou fenótipo M2, capazes de suprimir a função dos macrófagos M1 e influenciar na angiogênese e no reparo tecidual. O anticorpo CD68 reconhece os macrófagos M1 e M2, enquanto o anticorpo CD163 é específico para a identificação apenas de macrófagos M2. Objetivo: Investigar a presença dos TAMs em uma série de casos de carcinoma epidermoide (CE) de língua, associando-a à ocorrência de metástase. Material e métodos: A técnica imuno-histoquímica foi utilizada para avaliar a imunopositividade ao CD68 e CD163 em 27 casos de CE de língua. Resultados: A porcentagem de macrófagos CD68 positivos foi maior do que a de macrófagos CD163 positivos em todos os espécimes estudados. Comparando a imunomarcação de CD68 e CD163 nos grupos estudados, verificou-se que nos casos sem metástase havia maior proporção de células CD68 positivas em relação às CD163 positivas, o que foi estatisticamente significativo. Conclusão: Diante desses resultados, observou-se a predominância de macrófagos M1 em casos de CE de língua sem metástase, sugerindo a influência dessas células no comportamento clínico da lesão.
ABSTRACT
Objectives: To evaluate the expression of sphingosine kinase 1 (SPK1) in the bladder wall in patients with neurogenic lower urinary tract dysfunction and its association with clinical, urodynamic and pathological features. Materials and Methods: The expression of SPK1 was studied in bladder wall specimens obtained from cystectomy using immunohistochemistry in ten patients with spinal cord injury (n=8) or multiple sclerosis (n=2) with urodynamically proven neuropathic bladder dysfunction, and in controls (n=5). Inflammation and fibrosis were analysed with histological criteria and SPK1 expression was determined by individual immunohistochemical staining. Results: Significant increased SPK1 urothelial immunoreactivity was shown in patients compared to control group (p=0.03). By contrast, SPK1 immunoreactivity in patients was significantly decreased in the sub-urothelium, muscles and nerves, p=0.02; 0.01 and 0.003, respectively. Patients with neurogenic detrusor overactivity (NDO) had higher SPK1 urothelium expression than those without any DO (p=0.04). Conclusions: SPK1 is expressed in the human bladder wall, specifically the urothelium, in bladder specimens from patients with NDO. The role of SPK1 in the pathophysiology of NDO needs further elucidation.

SUMMARY Primary osteosarcoma of the breast (POB) is an extremely rare and aggressive tumor. Differential diagnosis of POB includes osteosarcoma of the chest wall and metaplastic breast carcinoma. Imaging tests that exclude the existence of a direct connection between the tumor and chest wall, as well as histopathological and immunohistochemical studies that rule out the presence of an epithelial component are required for the diagnosis of POB. We report a case of a 69-year old woman with POB. Imaging and pathological findings are presented. Therapeutic approach is discussed in the light of current knowledge, including potential complications.

Objective: CD20 expression was reported at different rates in patients with multiple myeloma. The importance of this B-cell antigen for plasma cells is still unknown. This study aimed to investigate CD20 expression of myeloma cells in bone marrow, and any relationship between the stage of disease, isotype and clinical features. Methods: Sixty-one patients who were admitted to the hematology clinic of the Adnan Menderes Medical School with the diagnosis of multiple myeloma according to the criteria of the "International Myeloma Working Group" were enrolled in this study. Age, gender, Durie-Salmon stage, history of autologous hematopoietic stem cell transplantation, and the distribution pattern and positivity of CD20 expression on multiple myeloma cells in bone marrow were evaluated. The Mann-Whitney U and chi-square tests were used for statistical analysis with a p-value < 0.05 being accepted as statistically significant. Results: Thirty patients (48.9%) had positive scores for CD20 with the distribution pattern being most likely interstitial in 55.6% of the cases. There was no statistically significant difference between immunohistochemical positivity for CD20 expression on multiple myeloma cells, immunoglobulin type, and the stage of disease. Conclusion: The combination of immunohistochemical studies with flow cytometry may reveal the importance of CD20 positivity in patients with multiple myeloma more clearly. .

ABSTRACT
Background Extracellular matrix (ECM) has various kinds of types and important biological function.The important role of ECM during choroidal neovascularization (CNV) arouse attention.Intercellular adhesion molecule-1 (ICAM-1), which is one of ECMs, involves in the formation of blood vessels, but the relationship between CNV and ICAM-1 is still unknown.Objective This study was to observe the dynamic expression of ICAM-1 in krypton laser-induced CNV and explore the effect of ICAM-1 on CNV.Methods Forty-eight healthy male clean BN rats were randomly divided into post-photocoagulation 1-week group,2-week group,3-week group,4-week group, 5-week group, 6-week group, 7-week group and 8-week group.Laser-induced CNV models were monocularly established and the fellow eyes served as the normal controls.Fundus fluorescein angiography (FFA) was carried out to quantitate the leakage degree (absorbency).The eyeballs were enucleated on various time points,and CNV areas were assessed by hematoxylin and eosin staining;immunohistochemistry and in situ hybridization assay were employed, respectively, for the detection of relative expression levels of ICAM-1 protein and mRNA (absorbency).The use and care of the animals complied with the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Committee.Results After laser photocoagulation,the retinal inner and outer nuclear layers were ruptured and invaginated.Disruption of Bruch membrane and macrophages migrating to the photocoagulation zone were seen under the optical microscope.The proliferation of fibroblasts and vascular endothelial cells was exhibited.ICAM-1 protein was mainly expressed in vascular endothelial cells,retinal pigment epithelium (RPE) cells and macrophages,and ICAM-1 mRNA was mainly expressed in the outer nuclear layer.Statistically significant differences were found in the fluorescence leakage degree, the relative expression levels of ICAM-1 protein and mRNA as well as CNV areas among the groups (F=178.839, 739.077,2 463.508,194.434, all at P＜0.05).The gradually enlarged CNV area, increased fluorescence leakage, up-regulation of ICAM-1 protein and mRNA expressions were matched with the extension of time after photocoagulation and peaked in the post-photocoagulation 8-week group.Conclusions The expressions of ICAM-1 protein and mRNA up-regulate upon the increase of CNV area and fluorescein leakage, suggesting that ICAM-1 might play an important role in CNV development.
ABSTRACT
Background Venous malformation damages the local tissue severely because of the progressive development and often presents with invasive biological behavior.Galectin-3 (Gal-3) is proved to be closely associated with local invasion of malignant tumor.Studying the role of Gal-3 on tissue invasion in venous malformation of ocular region is of important clinical significance.Objective This study was to explore the role of Gal-3 protein and mRNA expression in venous malformation of ocular region.Methods One hundred and eighteen pathological sections were collected from ocular venous malformation patients who received surgery in Department of Hemangioma Surgery,People's Hospital of Henan Province and Henan Eye Institute from June 2009 to June 2014.The specimens were further diagnosed by histopathological examination.Then the expressions of Gal-3 protein and mRNA in venous malformation of ocular region were detected by using immunohistochemistry and in situ hybridization and compared with 20 pieces of distal cutting edge specimens which were evidently normal.The associations of Gal-3 positive expressions with invasion and configuration of lesions were analyzed.Results Pathological examination showed that venous malformations tissues contain many big blood vessels lacuna, lined with fiat endothelial cells.Immunochemistry and in situ hybridization exhibited that Gal-3 protein and mRNA were expressed in the cytoplasm and nuclei.The positive expression rates of Gal-3 protein and mRNA in the venous malformation tissues were 55.93％ (66/118) and 59.32％ (70/118) , but those in the normal tissue were 15.00％ (3/20) and 20.00％ (4/20) ,showing significant differences between them (x2 =11.461, 10.633, both at P＜0.05).No significant differences were seen in the positive expression rates of Gal-3 protein and mRNA between the patients aged ≤ 12 years and ＞12 years or different genders (age: x2 =0.334,0.128;both at P＞0.05.gender:x2 =0.606,1.155;both at P ＞0.05).The incidence rate of invading ocular deep tissues was significantly higher in the Gal-3-positive groups than that in the Gal-3-negative groups of protein and mRNA (protein :x2 =32.688, P＜0.05;mRNA : x2 =23.695, P＜0.05).In the Gal-3-negative groups,96.15％ (Gal-3 protein negative group) and 97.92％ (Gal-3 mRNA negative group) lesions showed the spherical shape with clear boundaries.The lesions texture with the fuzzy boundaries and the incidences of vague structure in lesions were significantly higher in the Gal-3-positive groups than that in the Gal-3-negative groups of protein and mRNA (protein :x2 =28.255, P＜0.05;mRNA : 28.186, P＜0.05).Conclusions Gal-3 expression rate is raised in the deep tissue-invaded and texture disorder ocular venous malformation.These results suggest that invasion and damage of ocular venous malformation are associated with the up-regulation of Gal-3.

Introdução: A literatura indica uma correlação entre estrogênio elevado no soro e sintomas nasais ou alterações inflamatórias na mucosa nasal. Os receptores de estrogênio tendem a ser controlados por retroalimentação negativa, para evitar um estímulo nocivo sobre as diversas funções corporais em períodos de hiperestrogenismo. Propomos uma hipótese em que os mecanismos que regulam a expressão de receptores de estradiol na mucosa nasal estão ausentes em alguns pacientes, e a sua concentração permanece estável mesmo em períodos de elevada concentração sérica hormonal, o que pode conduzir a sintomas locais na mucosa nasal. Desenho do estudo: Estudo prospectivo experimental. Objetivo: Determinar se altos níveis de estrogênio induzem à redução no número de receptores de estrogênio na mucosa nasal. Material e método: Trinta cobaias foram submetidas à biópsia da concha nasal, recebendo 0,5 ml de cipionato de estradiol por via intraperitoneal por trinta dias consecutivos. Em seguida foram obtidas amostras da concha nasal contralateral. As análises imuno-histoquímicas dos receptores de estrógeno foram realizadas antes e depois da hormonioterapia. Resultados: O grupo pós-tratamento mostrou uma redução da expressão dos receptores (p = 5,2726-5). Conclusão: Redução na expressão do receptor de estrogênio nasal foi encontrada após trinta dias de administração de estradiol. .
Introduction: Some clinical trials revealed a correlation between increased serum estrogen and nasal symptoms or inflammatory changes in nasal mucosa. Estrogen receptors tend to be controlled by a negative feedback, to avoid a deleterious stimulus over several body functions while in hyperestrogenic periods. This study proposes a hypothesis where mechanisms regulating expression of estradiol receptors in nasal mucosa are absent in some patients, and their concentration remains steady even in periods of high serum hormonal concentration, potentially leading to local estrogenic symptoms in nasal mucosa. Study design: This was an experimental prospective study. Aim: To determine whether estrogen levels induce the reduction of the number of estrogen receptors in the nasal mucosa. Methods: In the present study, 30 adult male guinea pigs were subjected to a biopsy of the middle nasal turbinate and received 0.5 mL of estradiol cypionate intraperitoneally for 30 consecutive days. Afterwards, samples from contralateral middle turbinate were obtained. Immunohistochemical analysis of estrogen receptors were performed pre- and post-treatment. Results: The post-treatment group showed reduction of receptor expression when compared to the pre-treatment group. (p = 5.2726-5). Conclusion: A reduction in the expression of the nasal estrogen receptor was observed after 30 days of estradiol administration. .

Materiais e Métodos: Sessenta ratas foram divididas em quatro grupos (n = 15) de acordo com o tratamento: Grupo 1- ratas submetidas à cirurgia sham com alvéolos preenchidos com coágulo; Grupo 2-ratas submetidas à cirurgia sham com alvéolos preenchidos com Biosilicato cristalino; Grupo 3-ratas ovarectomizadas com alvéolos preenchidos com coágulo; e Grupo 4- ratas ovarectomizadas com alvéolos preenchidos com Biosilicato cristalino. Após 7, 14 e 28 dias os animais foram sacrificados e análises histomorfométricas (histologia e histometria) e imunoistoquímicas (Osteopontina e Osteocalcina) foram realizadas. A comparação dos resultados foi realizada utilizando o programa estatístico Assistat 2013 para Windows através da Análise de Variância e teste de Mann-Whitney, com resultados significantes sendo encontrados quando p≤0.05. Resultados: No período de 7 dias, os Grupos 1 e 3 apresentaram resultados superiores e estatisticamente maiores do que os Grupos 2 e 4 (p<0.05) quanto à formação óssea. Após o período de 14 dias as diferenças estatísticas mantiveram-se, com os Grupos 1 e 3 apresentando diferença estatisticamente significante maiores aos Grupos 2 e 4 (p<0.05). Aos 28 dias, a diferença estatística significativa permaneceu entre os mesmo Grupos estudados, sendo que nos grupos implantados com o Biosilicato cerca de 60% do alvéolo já havia sido preenchido por osso novo. A imunoistoquímica revelou expressão das proteínas Osteocalcina e Osteopontina, principalmente nos animais submetidos à cirurgia de ovarectomia. Conclusões: Os Grupos 1 e 3 foram os que apresentaram os melhores resultados durante todo o estudo, com o Biosilicato cristalino apresentando resultado favorável na reparação óssea sem contudo ser observada a absorção do biovidro. As análises imunoistoquímicas demonstraram que os animais submetidos a ovarectomia apresentaram uma maior...

After 7, 14 and 28 days the animals were sacrificed and histomorphometric analysis (histology and histometric) and immunohistochemical (Osteopontin and Osteocalcin) were measured . The comparison of the results was performed using the statistical program Assistat 2013 for Windows by Analysis of Variance and Mann-Whitney tests, with significant results being found when p ≤ 0:05 . Results: During the 7- day period, Groups 1 and 3 showed better and significantly higher results in bone formation than Groups 2 and 4 (p<0.05). After 14 days the statistical differences remained between Groups 1 and 3 and Groups 2 and 4 (p<0,05). At 28 days, the statically difference remained significant between the same Groups, while the groups implanted with Biosilicate presented about 60% of the socket filled by new bone. Immunohistochemistry revealed expression of proteins osteocalcin and osteopontin, especially in animals subjected to ovariectomy surgery. Conclusions: Groups 1 and 3 were those with the best results throughout the study, with the crystalline Biosilicate presenting favorable result in bone repair without bioglass resorption. The immunohistochemical analysis showed that animals subjected to ovariectomy had a higher signaling in Ostecalcina and Osteopontin proteins...

Objetivos: Avaliar o processo de reparo alveolar em ratas ovarectomizadas após implante com Biosilicato cristalino. Materiais e Métodos: Sessenta ratas foram divididas em quatro grupos (n = 15) de acordo com o tratamento: Grupo 1- ratas submetidas à cirurgia sham com alvéolos preenchidos com coágulo; Grupo 2-ratas submetidas à cirurgia sham com alvéolos preenchidos com Biosilicato cristalino; Grupo 3-ratas ovarectomizadas com alvéolos preenchidos com coágulo; e Grupo 4- ratas ovarectomizadas com alvéolos preenchidos com Biosilicato cristalino. Após 7, 14 e 28 dias os animais foram sacrificados e análises histomorfométricas (histologia e histometria) e imunoistoquímicas (Osteopontina e Osteocalcina) foram realizadas. A comparação dos resultados foi realizada utilizando o programa estatístico Assistat 2013 para Windows através da Análise de Variância e teste de Mann-Whitney, com resultados significantes sendo encontrados quando p≤0.05. Resultados: No período de 7 dias, os Grupos 1 e 3 apresentaram resultados superiores e estatisticamente maiores do que os Grupos 2 e 4 (p<0.05) quanto à formação óssea. Após o período de 14 dias as diferenças estatísticas mantiveram-se, com os Grupos 1 e 3 apresentando diferença estatisticamente significante maiores aos Grupos 2 e 4 (p<0.05). Aos 28 dias, a diferença estatística significativa permaneceu entre os mesmo Grupos estudados, sendo que nos grupos implantados com o Biosilicato cerca de 60% do alvéolo já havia sido preenchido por osso novo. A imunoistoquímica revelou expressão das proteínas Osteocalcina e Osteopontina, principalmente nos animais submetidos à cirurgia de ovarectomia. Conclusões: Os Grupos 1 e 3 foram os que apresentaram os melhores resultados durante todo o estudo, com o Biosilicato cristalino apresentando resultado favorável na reparação óssea sem contudo ser observada a absorção do biovidro. As análises imunoistoquímicas demonstraram que os animais submetidos a ovarectomia apresentaram uma maior...

BackgroundPterygium is an ocular surface disease of abnormal cell proliferative kind and angiogenesis plays an important role in its development and recurrence.Several anti-angiogenic therapies have been used to treat pterygium,but there very few studtes for the in vivo observation of the microvessles in pterygium.ObjectiveThis study was to observe angiogenesis in pterygium with a high-resolution confocal microscope in vivo and to perform immunohistochemical study in vitro.MethodsA prospective case-controlled study was designed.Twenty eyes of 20 consecutive patients with primary pterygia and 20 age- and sex-matched patients with inner eye diseases and strabismus with normal conjunctiva were enrolled in this study.An in vivo confocal microscopy imaging system (Heidelberg Retina Tomograph Ⅱ Rostock Cornea Module) was used to collect microvascular pictures from the anterior part of pterygia and normal nasal conjunctiva of controls,and then immunochemistry was performed to examine the expression of CD31 in microvessel in vitro.The vascular density values were compared between these two groups.The correlation of vascular density values between in vivo Heidelberg Retina Tomograph and in vitro immunohistochemistry was calculated.Written informed consent was obtained from pationts before any examination and surgery.ResultsUnder the in vivo confocal microscope,the microvessel density was (8929±2993) μm/mm2 and (4202 ±692)μm/mm2,respectively,in pterygium and the normal conjunctiva group with a statistically significant difference between them (t =6.881,P＜0.01 ).Immunochemistry revealed that the expression of CD31 to measure vascular density was ( 21.00 ± 4.06/400 × field ) and ( 6.07 ± 1.75/400 × field ) in pterygium and the normal conjunctiva group,showing significant difference (t =12.312,P＜0.01 ).Positive correlations were found in the vascular density values between in vivo corneal laser confocal microscopy examination and in vitro immunochemistry examination in both the pterygium group and normal conjunctiva group (pterygium group:r=0.649,P＜0.01 ;normal conjunctiva group: r=0.572,P＜0.01 ) ConclusionsIn vivo confocal microscopy imaging is superior to in vitro immunochemistry in evaluating the microvessel of pterygium.The results of this study offer a new way index for further investigation of the biological behavior of pterygium and its mechanism.
