1. The association between the histopathological features and microsatellite instability in young patients with urothelial carcinoma of the bladder
SUMMARY OBJECTIVE: Bladder cancer under the age of 40 is extremely rare. Bladder cancer development involves complex and multi-stage processes, one of which is the DNA damage repair mechanism. In this retrospective study, we aimed to evaluate the histopathological features of bladder urothelial carcinoma seen in patients under 40 years of age and tumor micr

2. MAGNETIC RESONANCE CHOLANGIOPANCREATOGRAPHY (MRCP) VERSUS ENDOSONOGRAPHY-GUIDED FINE NEEDLE ASPIRATION (EUS-FNA) FOR DIAGNOSIS AND FOLLOW-UP OF PANCREATIC INTRADUCTAL PAPILLARY MUCINOUS NEOPLASMS
RESUMO Racional: A neoplasia intraductal mucinosa papilífera (NIMP) está sendo diagnosticada com maior frequência. O método mais utilizado para diagnóstico é a tomografia computadorizada. No entretanto, a colangiopancreatoressonância (CPRM) proporciona melhor caracterização tipo e extensão. A ecoendoscopia com punção por agulha fina (EPAAF), por

3. Clinical-epidemiological, anatomic-pathological, histochemical and immunohistochemical characterization of renal cystadenocarcinoma-nodular dermatofibrosis syndrome in 11 German Shepherd dogs
RESUMO: São descritos 11 casos da síndrome cistadenoma/cistadenocarcinoma-dermatofibrose nodular (CR-DN) em cães Pastor Alemão, diagnosticados entre janeiro de 1994 e janeiro de 2018 no Laboratório de Patologia Veterinária da Universidade Federal de Santa Maria (LPV-UFSM). Os cães afetados foram oito machos e três fêmeas, estabelecendo-se uma relaç

4. Diagnostic performance of thyroid ultrasound in Hürthle cell carcinomas
ABSTRACT Objective Hürthle cell carcinomas (HCCs) of the thyroid have been recently reclassified as a separate entity due to their distinct clinical and molecular profiles. Few studies have assessed the ability of preoperative characteristics in differentiating HCCs from Hürthle cell adenomas (HCAs) due to the low prevalence of both lesions. This study a

5. Aggressive papillary thyroid carcinoma in a child with type 2 congenital generalized lipodystrophy
SUMMARY Thyroid carcinoma (TC) is rare in children, particularly in those aged < 10 years. Several studies have demonstrated a correlation between neoplasms and hyperinsulinemia and insulin resistance, which are often associated with a higher risk for and/or aggressiveness of the neoplasm. Congenital generalized lipodystrophy (CGL) with autosomal recessive i

6. Urothelial neoplasm of the bladder in childhood and adolescence: a rare disease
ABSTRACT Purpose: Bladder tumors are rare in children and adolescents. For this reason, the diagnosis is sometimes delayed in pediatric patients. We aimed to describe the diagnosis, treatment, and follow-up methods of bladder urothelial neoplasms in children and adolescents. Materials and Methods: We carried out a retrospective multicenter study involving

7. Detecção da mutação T1799A do gene BRAF em células de carcinoma papilífero obtidas por punção aspirativa com agulha fina / Detection of BRAF gene mutation T1799A in papillary carcinoma cells obtained by fine needle aspiration
O câncer da tireoide é a neoplasia endócrina mais comum, sendo responsável por cerca de 1 a 2% das neoplasias malignas da tireoide. Atualmente, a patogênese molecular do carcinoma papilífero da tireoide (CPT) tem sido relacionada à ativação aberrante da via de sinalização MAPK, desencadeada por mutações em diversos oncogenes. Destas, a mutação

8. Microcalcificações amorfas agrupadas na mamografia digital de campo total: correlação anatomopatológica / Grouped amorphous microcalcifications in full-field digital mamography: anatomopathologic correlation
PURPOSE: To determine the anatomopathological correlation of grouped amorphous calcifications (the most tenuous of suspicious calcifications) disclosed on full-field digital mammography, given the enhanced characterization of calcifications provided by digital mammography. METHODS: A retrospective study of mammographic reports classified as BI-RADS® categor

9. Pesquisa da mutação T1799A do gene BRAF e a presença de metástases linfáticas no carcinoma papilífero da tireoide / Analysis of the T1799A BRAF mutation and lymph node mestastases in papillary thyroid carcinoma
Muitos pacientes submetidos à tireoidectomia por Carcinoma Papilífero da Tireoide (CPT) têm doença linfonodal subclínica no momento da cirurgia. A mutação BRAF T17799A (V600E) é um evento comum no CPT e alguns estudos demonstram correlação entre a mutação e características de maior agressividade tumoral, incluindo a presença de metástases linf

10. NDRG1 protein overexpression in malignant thyroid neoplasms
OBJECTIVES: The aim of this study was to examine the expression of the N-myc downstream-regulated gene 1 protein in benign and malignant lesions of the thyroid gland by immunohistochemistry. INTRODUCTION: N-myc downstream-regulated gene 1 encodes a protein whose expression is induced by various stimuli, including cell differentiation, exposure to heavy metal

11. Analise da expressão do gene BRAF e suas possiveis implicações diagnosticas e prognosticas para pacientes portadores de carcinoma papilifero da tireoide / BRAF expression may help identify malignant nodules and define outcomes in papillary thyroid cancer patients
Background: Thyroid cancer is the most common endocrine malignancy, corresponding to 1% of all human neoplasms. Thyroid nodules are very frequent, mainly in women over 60 years. The relationship of BRAF gene with papillary thyroid tumorigenesis is well recognized in the literature. Its BRAFV600E mutation has been related to tumor aggressiveness and patients�

12. Analise critica da expressão do gene da mucina 1(MUC1) no carcinoma papilifero da tireoide : correlações clinicas e anatomo-patologicas / MUC1 critical gene expression analysis in th papillary thyroid cancer : clinical and pathological correlations
The over expression of MUC1 has been related with the worst prognosis in malignancies like breast and pancreas cancer. We know that around 20% of the patients with differentiated thyroid cancer (DTC) can develop local and/or distant recurrences and because of that we decide to analyze the MUC1 gene in patients with DTC and tried to relate it with clinical an
