Introduction: Follicular thyroid cancer (FTC) accounts for 12% of differentiated thyroid cancers (DTC). It is frequently complicated by bone metastasis (BM), which impact quality of life (QOL) and decreases the 10-year survival rate to 13-21%.Case Report: A 53-year-old woman followed at the Pain Clinic for over 10 years for lower back pain, had been operated three years before due to lumbar disc herniation. Pain relapsed one year after surgery and was re...

Introduction: Graves’ disease (GD) is caused by TSH receptor antibodies (TRAbs) which stimulate thyroid activity. Initial treatment usually relies on antithyroid drugs (ATDs), mainly methimazole, carbimazole or propylthiouracil (PTU). These drugs inhibit the enzyme thyroperoxidase, blocking the synthesis of T3 and T4. Definitive therapeutic options include radioactive iodine and total thyroidectomy which are usually reserved for patients who do not tolerate or respond to ...

Introduction: Adrenal incidentalomas are a frequent finding (1.4-7.3% on abdominal CT) and increasingly common with age, obesity, diabetes and hypertension. When approaching adrenal masses, clinicians should exclude malignancy and hormonal hypersecretion. Black adrenal adenomas (BAA), first reported in 1938, are rare benign adrenocortical tumours with black/brown appearance, containing lipofuscin. Most are non-functional, rarely inducing hypercortisolism. We present a case of ...

Introduction: Adrenocortical carcinoma (ACC) is a rare neoplasm with a variable but overall poor prognosis. The presentation is heterogeneous usually with mass effect and less often with evidence of hormonal secretion. About half of cases the tumors are hormonally active most commonly with cortisol secretion followed by sexual hormones production, being rare the aldosterone secretion.Case report: A 41-year-old male presented with hypertensive crisis and ...

Introduction: Amyloidosis results from deposition of insoluble proteins in the extracellular space. It can be both primary or secondary to chronic inflammatory diseases. Although microscopic thyroid involvement is common, cases in which it becomes clinically evident (amyloid goiter) are rare.Case report: Woman, 45 years. In 2009, she was diagnosed with Crohn’s disease after Bartholin’s gland abscess excision and evaluation for weight loss, anem...

X-linked adrenoleukodystrophy (X-ALD) is a metabolic disorder caused by mutations in the ABCD1 gene leading to accumulation of very long-chain fatty acids (VLCFA) in plasma and all tissues, including the white matter of the brain, the spinal cord and adrenal cortex. There is an estimated incidence of 1 in 17.000 new-borns. The clinical features are variable ranging from primary adrenal insufficiency and progressive myelopathy to cerebral demyelination.Th...

Background: Thyroid AUS/FLUS lesions continue to be a grey area regarding the surgery to be carried out. Our aim was to create a predictive malignancy score to help in surgical decision.Methods: Retrospective study of 2981 patients and 3557 thyroid Fine-needle aspirations (FNAs) between January 2012 to December 2014. Ultrasound and cytological findings considered suspicious by the ATA guidelines were analyzed. Malignant group was compared with a control ...

Germline aryl hydrocarbon receptor-interacting protein (AIP) mutations are responsible for 30% of pituitary gigantism cases. However, pathological accelerated growth and/or tall stature can be unrelated to the growth hormone (GH) axis, and may occur in isolation or as part of a syndrome, such as in Klinefelter, Marfan or Sotos syndromes. We report a five-generation kindred with two brothers with pituitary gigantism due to AIP mutation-positive GH-secreting pi...

Background: Serum thyroglobulin (Tg) is a reliable tumor marker in patients with differentiated thyroid carcinoma (DTC). Distant metastases of DTC, particularly in the lung, normally presents with higher levels of Tg, which is useful to follow the disease evolution. We describe a patient with DTC with lung metastases, with undetectable Tg and Tg-antibodies (TgAb).Clinical case: A 52-year-old woman underwent a subtotal thyroidectomy in 1993 because of a g...

Background and aims: Maternal BMI and weight gain are associated with maternal and fetal complications in gestational diabetes (GD), but their relative contribution is not clearly defined. Our aim was to determine the influence of BMI and weight gain in the evolution of GD.Material and methods: Multicenter, retrospective study of women diagnosed with GD at the medical centers of the Portuguese Group for the Study of Diabetes and Pregnancy in 2011. We use...
