The simultaneous occurrence of MTC and PTC in the same thyroid can be observed as a mixed tumour folliculo-medullar (OMS 1988) or as a collision tumour separated by normal thyroid parenchyma, which has only been described in less than thirty patients. We report two cases.Case 1: A 72 years old woman who underwent total thyroidectomy for a multinodular goiter. Histology showed a 2.5 cm CPT in the left lobe and a 4.5 cm CMT in the right lobe. She received ...

Introduction: Abnormal thyroid function is the most common disease in endocrinology and its screening of made by plasmatic (TSH), followed by (fT4) determination if abnormal. (fT3) determination is only used when pathological (TSH) and normal (fT4) are found, even if there is no evidence supporting this procedure, apart from the greater technical difficulty of measuring (fT3) due to its lower plasma concentration.Material and Methods: Observational retro...

Introduction: CCHD comprises a number of different congenital heart defects associated with elevated pulmonary artery pressure and pulmonary vascular resistance, resulting in a reversed or bidirectional shunt (Eisenmenger syndrome). These entities develop systemic hypoxia. Pheochromocytoma and paraganglioma (PHEO/PG) are neuroendocrine tumours. Several inheritance genetic alterations have been reported in PHEO/PG syndromes. A pathogenic association between these entities is pr...

The clinical significance and potential morbidity of papillary thyroid microcarcinomas (PTMC) is discussed. Particularly the differences between those PTMC identified postoperatively in histological examination (incidentals), and those diagnosed preoperatively (non-incidentals). We retrospectively analysed differences in clinical presentation and course after treatment in these two groups. The study population consisted of 199 patients with PTMC who underwent surgery from 2000...

Introduction: BRAF(V600E) mutation has received great attention to improve risk stratification in patients with PTC. Its prognostic value in the different Cytological variants (CytV) of PTC is not well established. The aim of this study was to investigate differences in clinicopathological features according to CytV, among patients harbouring the mutation.Methods: We evaluated 102 patients with pathological diagnosis of PTC. All of them underwent total t...

Introduction: Hypoparathyroidism (hypoPT) is the most frequent complication after thyroid surgery, usually as transient hypocalcaemia. Permanent parathyroid lesion is less frequent, but it can extend hospital stay and complicate postoperative management. Several preoperative factors predicting the development of hypoPT have been identified, including advanced age, hyperthyroidism, surgical experience and others. We evaluate the role of some potentially predictive factors in ou...

Introduction: BRAF (V600E) mutation is the most frequent detected genetic change in papillary thyroid cancer (PTC) and its presence has been related to aggressive clinical and pathological features. Lymph node metastases (LNMx) are common in PTC and are associated with an increase in loco-regional recurrence. However, prophylactic lymph node dissection is not routinely performed because of high rate of surgery complications. Therefore, there is a need to find a good marker to ...

Fine-needle aspiration cytology (FNAC) remains the mainstay in the study of thyroid nodules, with cytologic adequate specimens in almost 85% of cases in expert hands. Apart from the limitation of inadequate samples, there are false negative diagnoses in some cases, particularly in larger (>3 cm) nodules. Considering this, Large-needle biopsy (LNB) could be useful to improve diagnostic precision. We review the pathology reports (PR) of more than 100 patients operated since ...

Early diagnosis of CS could reduce the morbidity and mortality associated with endogenous hypercortisolism. Many clinical methods have been proposed to establish suspicion of CS, but they show a poor positive predictive value (PPV) and are sometimes difficult to assess. Assuming the well-known influence of hypercortisolism on white blood cell (WBC) count, we evaluated its potential usefulness as a screening test to trigger this suspicion. We analysed WBC count around the diagn...

Introduction: Maternal clinical thyroid disorders can cause reproductive complications. However, the effects of mild thyroid dysfunction are controversial. The impact of SH and thyroid autoimmunity on miscarriages, obstetric and perinatal outcomes are not yet well established and the effect of levothyroxine replacement in pregnant women with SH is unclear. The aim of this study was to evaluate the impact of thyroid autoimmunity in early pregnancy on obstetric and perinatal out...
