13. First description of basaloid carcinoma of the canine mammary gland: case report
RESUMO O objetivo deste relato de caso é descrever as características histopatológicas e imuno-histoquímicas do primeiro relato de carcinoma basaloide na glândula mamária canina. Duas cadelas foram atendidas com tumores na glândula mamária e foram submetidas à mastectomia. A avaliação microscópica demonstrou células epiteliais arranjadas em um p

14. Expressão de neurotrofinas e de seus receptores no osteossarcoma primário.
RESUMO Objetivo: determinar a expressão de neurotrofinas e seus receptores tirosina quinases em pacientes com osteossarcoma (OS) e sua correlação com desfechos clínicos. Métodos: biópsias de tumores primários de pacientes com OS tratados em uma única instituição, consecutivamente, entre 2002 e 2015, foram analisados através de imuno-histoquímic

15. Wobbly syndrome in an Africa pygmy hedgehog (Atelerix albiventris): neuropathological and immunohistochemical studies
RESUMO: Um ouriço pigmeu africano de três anos de idade, nascido e domiciliado no Brasil, apresentou apatia, prostração e dificuldade em permanecer em estação. Os pais deste ouriço eram irmãos, mas não apresentaram sinais clínicos relacionados a esta condição. Com a piora dos sinais clínicos, o animal foi eutanasiado e encaminhado para necropsia

16. Lung cancer biopsy: Can diagnosis be changed after immunohistochemistry when the H&E-Based morphology corresponds to a specific tumor subtype?
OBJECTIVES: Advancements in non-small cell lung cancer treatment based on targeted therapies have made the differentiation between adenocarcinoma and squamous cell carcinoma increasingly important. Pathologists are challenged to make the correct diagnosis in small specimens. We studied the accuracy of an immunohistochemical panel in subclassifying non-small

17. Evaluation of prophylactic and therapeutic effects of sildenafil on acute radiation proctitis in rats
Abstract Purpose: To investigate the prophylactic and therapeutical effects of sildenafil in a model of acute radiation proctitis (ARP). Methods: All experimental procedures of this study was examined by histopathological, immunohistochemical and transmission electron microscopic analysis. Results: Our histopathological evaluations indicated significant

18. Expression of E-cadherin, Slug and NCAM and its relationship to tumor invasiveness in patients with acromegaly
Pituitary adenomas account for 10–15% of primary intracranial tumors. Growth hormone (GH)-secreting adenomas account for 13% of all pituitary adenomas and cause acromegaly. These tumors can be aggressive, invade surrounding structures and are highly recurrent. The objective of this study was to evaluate E-cadherin, Slug and neural cell adhesion molecule (N

19. The role of Osterix protein in the pathogenesis of peripheral ossifying fibroma
Abstract Peripheral ossifying fibroma (POF) is a reactive lesion of oral tissues, associated with local factors such as trauma or presence of dental biofilm. POF treatment consists of curettage of the lesion combined with root scaling of adjacent teeth and/or removal of other sources of irritants. This study aimed to analyze the clinical and pathological fea

20. Analysis of various potential prognostic markers and survival data in clear cell renal cell carcinoma
ABSTRACT Purpose Clear cell renal cell cancers frequently harbor Von Hippel-Lindau gene mutations, leading to stabilization of the hypoxia-inducible factors (HIFs) and their target genes. In this study, we investigated the relationship between vascular endothelial growth factor (VEGF), HIF-1α, HIF-2α, p53 positivity, microvessel density, and Ki-67 rates

21. Cutaneous metastases in a patient with no previous diagnosis of cancer: diagnostic challenge
Abstract: On rare occasions, skin lesions are the first local of metastatic manifestation of internal malignancies. In case of no previous diagnosis of these tumors, the approach of suspicious skin lesions becomes a challenge, especially in differentiating cutaneous metastases and adnexal primary neoplasms. Currently, besides epidemiologic, dermoscopic and h

22. MCM - 2 and Ki - 67 as proliferation markers in renal cell carcinoma: A quantitative and semi - quantitative analysis
ABSTRACT Introduction/Background: Fuhrman nuclear grade is the most important histological parameter to predict prognosis in a patient of renal cell carcinoma (RCC). However, it suffers from inter-observer and intra-observer variation giving rise to need of a parameter that not only correlates with nuclear grade but is also objective and reproducible. Proli

23. Immunohistochemical angiogenic biomarkers in hepatocellular carcinoma and cirrhosis: correlation with pathological features
OBJECTIVE To investigate immunohistochemical markers of angiogenesis and their association with pathological prognostic features in hepatocellular carcinoma and cirrhotic liver. METHODS Vascular endothelial growth factor, CD105, and cyclooxygenase-2 were immunohistochemically detected in 52 hepatocellular carcinoma tissue samples and 48 cirrhotic liver tis

24. Expression of CD90 and P75NTR stem cell markers in ameloblastomas: a possible role in their biological behavior
Abstract Multicystic and unicystic ameloblastomas are benign odontogenic tumors that present distinct biological behavior. The investigation of stem cells has become an important branch of tumor biology, with several studies addressing the possible role of these cells in tumor growth, angiogenesis, progression, infiltration and invasiveness. This study evalu
