13. Elastography for the evaluation of thyroid nodules in pediatric patients
Resumo Objetivo: Avaliar a utilidade da elastografia (usando compressão manual) como uma ferramenta adicional de diagnóstico em crianças e adolescentes com nódulos da tireoide. Materiais e Métodos: Este foi um estudo prospectivo realizado entre setembro de 2012 e agosto de 2013 em um hospital no Brasil. Realizamos elastografia, ultrassonografia e bió

14. Is thyroid nodule volume predictive for malignancy?
ABSTRACT Objective: We aimed to determine the roles of preoperative thyroid nodule diameter and volume in the prediction of malignancy. Subjects and methods: The medical records of patients who underwent thyroidectomy between January 2007 and December 2014 were reviewed. The nodule diameters were grouped as < 1 cm, 1-1.9 cm, 2-3.9 cm and ≥ 4 cm, and volu

15. Preoperative detection of TERT promoter and BRAFV600E mutations in papillary thyroid carcinoma in high-risk thyroid nodules
ABSTRACT Objectives: This observational study analyzed telomerase reverse transcriptase (pTERT) mutations in 45 fine-needle aspiration (FNA) specimens obtained from thyroid nodules followed by postoperatively confirmation of papillary thyroid cancer (PTC) diagnosis, examining their relationship with clinicopathologic aspects and the BRAFV600E mutation. Sub

16. A predictive model to distinguish malignant and benign thyroid nodules based on age, gender and ultrasonographic features
Resumo Introdução: Persiste na literatura uma discussão sobre uma ferramenta padronizada de apoio à decisão para o manejo de nódulos tireoidianos. Objetivo: Criar um modelo de previsão estatística para o manejo de nódulos tireoidianos. Método: Foram selecionados 204 casos de nódulos tireoidianos benignos e 57 malignos para o estudo retrospectiv

17. Does the Bethesda category predict aggressive features in differentiated thyroid cancer?
ABSTRACT Objective: To analyze the importance of preoperative cytology of thyroid nodules and its relationship with mortality risk, recurrence risk, dynamic stratification, and aggressive characteristics (vascular invasion, aggressive histology, incomplete tumor resection, extrathyroidal extension of the tumor, and presence of lymph node and distant metasta

18. 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

19. Reliability of Thyroid Imaging Reporting and Data System (TI-RADS), and ultrasonographic classification of the American Thyroid Association (ATA) in differentiating benign from malignant thyroid nodules
ABSTRACT Objective Ultrasonography (US) is the best diagnostic tool for initial assessment of thyroid nodule. Recently, data reporting systems for thyroid lesions, such as the Thyroid Imaging Reporting and Data System (TI-RADS) and American Thyroid Association (ATA), which stratifies the risk for malignancy, have demonstrated good performance in differentia

20. Coexistence of diffuse large B-cell lymphoma and papillary thyroid carcinoma in a patient affected by Hashimoto's thyroiditis
SUMMARY Papillary thyroid carcinoma (PTC) is the most common type of thyroid cancer. On the contrary, primary thyroid lymphoma (PTL) is a rare disease, accounting for 2% to 5% of all thyroid malignancies. Despite several cases in which both PTC and PTL arise in the setting of Hashimoto's thyroiditis (HT), the coexistence of both tumors in HT patients is very

21. Thyroid nodules with highly suspicious ultrasonographic features, but with benign cytology on two occasions: is malignancy still possible?
ABSTRACT Objective There is no information about the frequency of malignancy specifically in the case of thyroid nodules with highly suspicious sonographic features, but with two fine needle aspiration (FNA) showing benign cytology. This was the objective of the study. Subjects and methods We report the results of 105 patients with thyroid nodules consid

22. Increasing diagnostic effectiveness of thyroid nodule evaluation by implementation of cell block preparation in routine US-FNA analysis
ABSTRACT Objective Ultrasound-guided fine-needle aspiration (US-FNA) biopsy has proven to be an accurate and efficient tool in thyroid nodule evaluation. We evaluated whether cell block adds to the diagnostic accuracy of US-FNA. Subjects and methods Three hundred twenty-eight consecutive patients underwent US-FNA, cytology and cell block evaluation. Six

23. Percutaneous ethanol injection versus conservative treatment for benign cystic and mixed thyroid nodules
ABSTRACT Objective To evaluate the efficacy and safety of percutaneous ethanol injection (PEI) in reducing the volume of cystic and mixed thyroid nodules. Materials and methods A total of 36 patients with nodules treated with PEI and 13 individuals who declined PEI and were followed clinically or received other non surgical treatment (control group). Asses

24. Painless thyroiditis associated to thyroid carcinoma: role of initial ultrasonography evaluation
Even though it is a rare event, most associations of thyroid carcinoma with subacute thyroiditis described in the literature are related to its granulomatous form (Quervain’s thyroiditis). We present a patient with subacute lymphocytic thyroiditis (painless thyroiditis) and papillary thyroid cancer that was first suspected in an initial ultrasound evaluati
