25. Thyroid hormone resistance in two patients with papillary thyroid microcarcinoma and their BRAFV600E mutation status
Resistance to thyroid hormone (RTH) is a rare autosomal dominant hereditary disorder. Here in, we report two patients with RTH in whom differentiated thyroid cancer was diagnosed. Two patients were admitted to our clinic and their laboratory results were elevated thyroid hormone levels with unsuppressed TSH. We considered this situation thyroid hormone resis

26. Thyroid nodule: first manifestation of chronic lymphocytic leukaemia
The presence of chronic lymphocytic leukaemia (CLL) cells in the thyroid gland is most likely due to a secondary involvement by a systemic disease. The reported incidence of CLL involving the thyroid is extremely low, representing about 3–4% of all thyroid lymphoproliferative neoplasm. We report a rare case of CLL presenting initially in the thyroid gland.

27. Is Primary Hyperparathyroidism a Risk Factor for Papillary Thyroid Cancer? An Exemplar Study and Literature Review
Introduction Primary hyperparathyroidism (PHPT) is associated with several cancer types, including papillary thyroid carcinoma (PTC). Objective To explore further the relation between PHPT and PTC.
Methods By considering patients with PHPT as extra-suspicious for PTC, we studied an exemplar group of pati

28. Thyroid nodule management: clinical, ultrasound and cytopathological parameters for predicting malignancy
Although fine-needle aspiration cytology is considered to be the reference method for evaluating thyroid nodules, the results are inaccurate in approximately 10-30% of cases. Several studies have attempted to predict the risk of malignancy in thyroid nodules based on age, nodularity, thyrotropin values, thyroid autoimmune disease, hot/cold nodule status, and

29. Aspectos clínicos, ultrasonográficos, cintilográficos e cito-patológicos na predição de malignidade do nódulo tireoidiano / Role of clinical, ultrasound, scintigraphyc and cytological parameters to predict malignancy in thyroid nodule
Introdução: A punção aspirativa por agulha fina (PAAF) permanece como o procedimento de referência na avaliação dos nódulos de tireóide. No entanto, em cerca de 10 a 30% dos casos, o diagnóstico citológico é indeterminado. Alguns estudos recentes buscam estabelecer modelos de predição de risco para malignidade no nódulo de tireóide, correlaci

30. Alterações da PET-FDG na avaliação pré-operatória de pacientes com nódulos tireoidianos e correlação com marcadores imuno-histoquímicos / FDG PET abnormalities in preoperative evaluation of patients with thyroid nodules and association with immunohistochemical biomarkers
INTRODUÇÃO: Cerca de 80% dos nódulos de tireóide com citologia indeterminada são benignos. É possível que a tomografia por emissão de pósitrons (PET) com 2-[18F]- fluoro-2-desoxi-D-glicose (FDG) ajude a identificar quais dessas lesões são malignas. A captação de FDG depende da expressão de GLUTs (transportadores de glicose transmembrana) e hexo

31. 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�

32. A expressão galectina-3 como marcador de malignidade de neoplasias de tireóide
Fine needle aspiration biopsy is considered to be the best propedeutic method used in evaluation of a thyroid nodule. However, in some situations, it is impossible to cytologically distinguish a malignant and a begnin disease; therefore, surgeons must indicate thyroidectomy for a diagnostic purpose. This results that most suspect nodules are referred to surg

33. Plasma cell granuloma of the thyroid.
A thyroid nodule comprised numerous polyclonal plasma cells inside cellular fibroblastic stroma, with residual thyroid tissue in the centre of the nodule. There was no associated paraproteinaemia. The residual thyroid tissue suggests that the exuberant granulation tissue in this case represents an unusual reaction to a colloid nodule. As far as we know, this

34. Dysphagia with a thyroid nodule: is there a primary aerodigestive malignancy?
Three cases of laryngopharyngeal primary squamous cell carcinoma presenting with thyroid nodules are described. The key message to take away from these cases is that patients with advanced malignancy of the upper aerodigestive tract can present with a thyroid nodule.

35. Histoplasmosis of the Thyroid
Fungal infection of the thyroid is rare. Most reported cases have involved Aspergillus, Coccidioides, and Candida species in the setting of disseminated disease. Infection of the thyroid with Histoplasma capsulatum is rarely reported as part of disseminated disease, even in geographic areas where histoplasmosis is endemic. We report a 52-year-old woman with

36. Suppression of Pituitary TSH Secretion in the Patient with a Hyperfunctioning Thyroid Nodule
10 patients with a single hyperfunctioning thyroid nodule each were studied for pituitary thyrotropin (TSH) suppression. They were judged to be euthyroid on clinical grounds. The total thyroxine (T4D), free thyroxine (FT4), total triiodothyronine (T3D), and free triiodothyronine (FT3) were normal in most of the patients. Incorporation of 131I into the hyperf
