Follicular Neoplasms: Clinical, Sonographic and Cytological Determinants and its Histological Correlation

Couto J. , Martins R. , Santos A. , Monteiro P. , Torres I.

Introduction: Fine-needle biopsy(FNB) is an essential diagnostic tool in the evaluation of thyroid nodules, however, follicular neoplasm(FN) does not exclude malignancy. Some sonographic and cytological features have been described as being associated with increased risk of malignancy. The authors aimed to identify demographic, sonographic and cytologic features associated with malignancy in patients with a cytological diagnosis of FN.Methods: Descriptiv...

Diabetes insipidus in a patient with breast carcinoma

Couto J , Santos A P , Martins R , Giesteira L , Torres I

Introduction: Central diabetes insipidus (CDI) is characterized by a deficient secretion of anti-diuretic hormone (ADH), in which a large volume of hypotonic urine is eliminated. Pituitary metastatic disease is rare, accounting for 1% of all excised pituitary tumors and generally involves the posterior pituitary. Neoplasms that more often originate pituitary metastases are breast and lung cancer. Breast cancer (BC) is associated with pituitary secondary involvement in 5.3 to 2...

Lymphocytic chronic thyroiditis and papillary thyroid carcinoma: relation with prognostic factors

Martins R , Couto J , Santos A , Polonia A , Lobo C , Antunes L , Lucena I , Torres I

Introduction: Recent studies have shown that chronic lymphocytic thyroiditis is associated with increased risk of developing papillary thyroid carcinoma (PTC). Although still controversial, these carcinomas appear to have a better prognosis. This study aims to evaluate the presence of thyroiditis in thyroids with PTC and the association with histological variables of prognostic value, Tg and evidence of metastasis in 131I scan.Methods: Descrip...

Lower limb Merkel cell carcinoma with a single metastasis in a thyroid nodule

Martins R , Couto J , Santos A P , Ribeiro M , Giesteira L , Polinario A , Torres I

Introduction: Merkel cell carcinoma (MCC) is a rare, aggressive cutaneous malignancy, affecting predominantly caucasian and older individuals (slight male predominance). This neoplasm is associated with a high risk of local recurrence and regional lymph node involvement. Distant metastases are less frequent; they were described in liver, bone, CNS, skin, lung and spleen. The authors describe a clinical case of Merkel cell carcinoma with a single metastasis in a thyroid nodule....

Central diabetes insipidus: about two clinical cases

Nogueira C. , Matos M. , Esteves C. , Jorge G. , Couto J. , Neves C. , Queiros J. , Vinha E. , Bernardes I. , Carvalho D.

Introduction: Central diabetes insipidus (CDI) is produced by the destruction of the magnocellular neurons of the hypothalamic supraoptic and paraventricular nuclei which results in decreased arginine vasopressin (AVP) synthesis and secretion.Case report 1: Forty-five year old female, previously healthy, was observed in April 2011 complaining of polydipsia, polyuria, nocturia and weight loss since January. Diabetes mellitus (DM) was excluded and she was ...
