1. Immunohistochemical evaluation of HLA-G and FoxP3+ T regulatory cells in oral cavity and lower lip squamous cell carcinomas
Abstract: Human Leukocyte Antigen G (HLA-G) is a molecule involved in the tumor immunosuppression and also in the generation of regulatory T (Treg) cells, thus leading to evasion to the immune system host, and consequently, contributing to tumor progression in several cancers. The aim of this study was to evaluate the immunoexpression of HLA-G by tumor cells

2. Cutaneous metastasis of a breast cancer diagnosed 13 years before
AbstractMetastasis is defined as a neoplastic lesion originating from another primary tumor, with which it is no longer in contact. Cutaneous metastases result from lymphatic embolization, hematogenous or contiguous dissemination or also direct implantation during surgical procedures. In women, the tumor most likely to metastasize to skin is breast cancer, w

3. Metástase cerebral como apresentação inicial de adenocarcinoma papilífero de pulmão: relato de caso
Os autores descrevem um caso de paciente de 33 anos de idade com história de crises convulsivas isoladas sem qualquer antecedente, sendo diagnosticadas metástases cerebrais tendo como sítio primário um adenocarcinoma papilífero de pulmão. É enfatizada a investigação diagnóstica para metástase cerebral e avaliação prognóstica do adenocarcinoma p

4. Interobserver agreement for the spine instability neoplastic score varies according to the experience of the evaluator
OBJECTIVES: To evaluate the interobserver agreement for the Neoplastic Spine Instability Score (SINS) among spine surgeons with or without experience in vertebral metastasis treatment and physicians in other specialties. METHODS: Case descriptions were produced based on the medical records of 40 patients with vertebral metastases. The descriptions were then

5. Graduação histológica e expressão de metaloproteinases (MMP-9 e MMP-2) e seus inibidores (TIMP-1 e TIMP-2) na glândula mamária canina neoplásica / Histological grade and expression of matrix metalloproteinases (MMP-9 e TIMP-2) and their inhibitors (TIMP-1 and TIMP-2) in neoplastic canine mammary gland
Nas fêmeas caninas, as glândulas mamárias são os locais mais comuns para a ocorrência de neoplasias. Para avaliar o comportamento biológico dessas lesões empregam-se rotineiramente métodos histológicos descritivos que, associados à graduação histológica, auxiliam na predição prognóstica dessas enfermidades. Ainda, o desequilíbrio entre a qua

6. Avaliação da linfangiogênese em carcinoma de células escamosas de boca e de sua associação com metástases nodais
Recent studies have demonstrated that metastatic behavior of some tumors is facilitated by lymphangiogenesesis in primary tumor or in lymph node environment. In the present study of lymphangiogenesis 36 paraffin-embedded samples of oral squamous cell carcinoma (OSCC) and associated lymph nodes were used. Lymphatic vessels and microvessels densities (LVD and

7. Mechanisms of RON-mediated epithelial-mesenchymal transition in MDCK cells through the MAPK pathway
The epithelial-mesenchymal transition (EMT) is involved in neoplastic metastasis, and the RON protein may be involved. In the present study, we determined the role and the mechanisms of action of RON in EMT in Madin-Darby canine kidney (MDCK) cells by Western blot and cell migration analysis. Activation of RON by macrophage stimulating protein (MSP) results

8. Classification of brain tumor extracts by high resolution ¹H MRS using partial least squares discriminant analysis
High resolution proton nuclear magnetic resonance spectroscopy (¹H MRS) can be used to detect biochemical changes in vitro caused by distinct pathologies. It can reveal distinct metabolic profiles of brain tumors although the accurate analysis and classification of different spectra remains a challenge. In this study, the pattern recognition method partial

9. Diffuse Iris Melanoma in a Cat
Background: Diffuse iris melanoma is rare, although is the most common primary intraocular neoplasm in cats, and is an unusual variant of anterior uveal melanoma. This neoplasm is malignant with high potential methastazed. Affects olders cats without breed or sex predisposition. The diagnosis can be made with fine needle aspiration cytology of anterior segme

10. Corneal squamous cell carcinoma in a dog
Background: Squamous cell carcinoma (SCC) is a neoplastic disease of the squamous epithelial cells that has been rarely described in the literature. This neoplasm affects the eyelid, conjunctiva and third eyelid, as well as the cornea. Corneal SCC is a neoplastic lesion characterized by a pink, typically irregular mass protruding from the epithelial surface

11. RETROSPECTIVE STUDY OF 1,647 MAMMARY GLAND TUMORS IN DOGS / ESTUDO RETROSPECTIVO DE 1.647 TUMORES MAMÁRIOS EM CÃES
Mammary gland tumors are common in dogs and are the most common type of neoplasms of female dogs. The main purposes of this study were to establish the prevalence of the mammary gland tumors, as well as of its different histologic types (neoplastic and non-neoplastic), diagnosed in the Laboratório de Patologia Veterinária of the Universidade Federal de San

12. Prognostic value of podoplanin expression in intratumoral stroma and neoplastic cells of uterine cervical carcinomas
OBJECTIVE: To investigate the clinicopathological significance of podoplanin expression in the intratumoral stroma and neoplastic cells of early stage uterine cervical cancer. MATERIALS AND METHODS: A total of 143 patients with clinical stage I and IIA uterine cervical carcinomas underwent surgery between 2000 and 2007. Clinicopathological data and slides as
