The prevalence of obesity has greatly increased worldwide in the last decades, particularly in Europe and Portugal. It is associated with many health problems, including cardiovascular diseases, cancer and diabetes.Methods: Revision of the clinical records of all 61 patients who underwent bariatric surgery between 2013 and 2015. Analysis of their metabolic profile prior to surgery and its evolution after the operation.Results: 61 p...

Introduction: The update of 2015 American Thyroid Association (ATA) guidelines recommend that radioactive iodine (RAI) ablation therapy should be used in line with patients’ risk stratification. However, there is no consensus on benefits of post-operative RAI ablation in patients with low risk differentiated thyroid cancer (DTC). The aim of this study is to compare the outcomes of patients with low risk DCT submitted to RAI ablation with those who were not.<p class="a...

Background: To minimize potential harm from overtreatment of low-risk thyroid cancers, the 2015 American Thyroid Association (ATA) Guidelines recommend that radioactive iodine (RAI) ablation should not be routinely used in low-risk differentiated thyroid carcinoma (DTC). The present study aims to evaluate trends in RAI therapy in a tertiary center after the update of these Guidelines.Methods: Data from patients followed in a tertiary center with low-risk...

Tertiary hyperparathyroidism reflects parathyroid hyperplasia, with autonomous secretion of parathyroid hormone (PTH), in spite of high plasma calcium concentration. Parathyroidectomy is an efficient therapy for stabilization of calcium and PTH metabolism in patients with end-stage kidney disease.We report a case of a 68-year old man with end-stage kidney disease under hemodialysis for nine years, due to long-standing uncontrolled hypertension. He presen...

IntroductionGynecomastia is characterized by the abnormal enlargement of one or both male breasts due to proliferation of the glandular tissue, with many possible underlying causes. A documented rare cause of gynecomastia is chest trauma.Case reportWe present a case of a 53-year-old male patient, with a personal history of arterial hypertension and depressive disorder, medicated with fluoxetine, perindopril, ...

Introduction: A teratoma is a rare type of tumor deriving from the germ layer cells (ectoderm, mesoderm and endoderm), typically benign, more frequent in infants. Adult onset teratomas are most commonly gonadal cell tumors. Extra--gonadal teratomas generally affect the midline, most frequently anterior mediastinum, retroperitoneum, pineal and suprasellar area. Head and neck teratomas are an extremely rare entity and represent only 0.47–6% of all cases.<p class="abste...

IntroductionAdrenal cyst lesions are uncommon and only a few large series have been reported. The pathogenesis is unclear. Currently, adrenal cystic lesions are categorized into endothelial cysts, pseudocysts, epithelial cysts and parasitic cysts. In most cases they are found incidentally in asymptomatic patients or in patients with non-specific gastrointestinal symptoms. We describe three cases of adrenal cysts.Case report<p c...

IntroductionLeydig cell tumors are rare entities, representing less 0.1% of all ovarian tumors. Generally these tumors are benign and unilateral. Most originate from the hilus cells and, less frequently, from the ovarian cortical stroma. Leydig cell tumors are functioning tumors, frequently associated with virilization symptoms in post-menopausal women.Case reportWe report the case of a 77 year-old female pat...

IntroductionA rarely reported histologic subtype of the papillary thyroid cancer is the Warthin-like variant (WLPTC). This carcinoma resembles the Warthin tumour of the salivary gland by virtue of a papillary pattern of eosinophilic tumour cells associated with a rich lymphoplasmacytic infiltrate in the cores of the papillae. Due to the its rarity, the pathological characteristics and clinical behavior of WLPTC are not well doc...
