Introduction: Fine-needle aspiration cytology (FNAC) of thyroid nodules can be associated with non-diagnostic (ND) results, despite the usage of ultrasound (US) guidance. It is recommended to repeat the FNAC because of the possible risk of malignancy in these nodules.Aim: To evaluate the influence of demographic, clinical and echographic characteristics in the recurrence of ND FNAC in a thyroid nodule.Methods: Retrospective review ...

Background: Chordomas are rare, invasive and slow growing bone tumours with different locations. Parasellar chordomas are even more rare and the initial manifestations include visual and/or neurological symptoms. In addition, endocrine dysfunction may be present. We describe 4 cases of parasellar chordomas.Clinical cases: 1) Female, 55-years-old, reported headache associated with restriction of left eye movement for the past 3 months. Brain magnetic reso...

Introduction: Almost all type 1 diabetes mellitus (T1DM) patients have autoantibodies (ab) at disease onset. These ab prevalence varies according to patients’ age, origin and disease duration.Aim: Determine diabetes mellitus ab prevalence in a paediatric and adult T1DM Portuguese according to their age on diagnosis, gender and diabetes duration.Methods: Retrospective review of T1DM ab (glutamic acid decarboxylase 65 autoantibo...

Introduction: Autosomal dominant hypocalcemia (ADH) is a rare condition, caused by activating mutations in the calcium-sensing receptor (CASR) gene. Affected individuals have hypocalcemia with inappropriately low parathyroid hormone (PTH) levels.Case report: A 50-year-old woman, asymptomatic, was referred to our Endocrinology department for investigation of hypocalcemia detected in routine blood analysis (serum corrected calcium was 7.4 mg/dl &#...

Abstract: We report the case of a 65-year-old man who presented with erectile dysfunction to an appointment in our Endocrinology department. He referred fatigue, weight gain and constipation as secondary complaints that had been steadily evolving throughout the past 4 years. He denied other symptoms such as visual impairment or headaches as well as the consumption of any medications or drugs. His past medical history was unremarkable. On examination, BMI was 25.8 kg/m2</s...

Introduction: Hirsutism is the presence of terminal hair growth in females with a male distribution pattern. It affects 5-15% of women, being an important sign of androgen excess. The main causes of hirsutism are polycystic ovary syndrome (PCOS) and idiopathic hyperandrogenism. Other significant but less frequent causes of hirsutism include nonclassic congenital adrenal hyperplasia (NCAH), androgen-secreting tumors, and Cushing’s syndrome.Case repor...

Introduction: Primary thyroid lymphomas (PTL) account for 5% of all thyroid malignancies. Treatment and prognosis depend on tumor subtype. Contrasting with diffuse large B-cell lymphomas (DLBCL), that have an aggressive clinical course and higher maximum standardized uptake value (SUVmax) in Fluorine-18-fluorodeoxyglucose positron emission tomography (FDG-PET), thyroid extranodal marginal zone B-cell lymphomas of mucosa-associated lymphoid tissue (MALT) usually show an indolen...

Introduction: Von Hippel-Lindau disease (VHLD) is a rare autosomal-dominant syndrome, characterized by the development of multiple cysts and tumours, namely retinal and central nervous system hemangioblastomas, renal cell carcinoma (RCC), phaeochromocytoma, pancreatic endocrine tumours (PET) and endolymphatic sac tumours.Most germinal mutations are missense, related to a high risk for presenting phaechromocytoma (specially if Arg167Trp mutation im...

Introduction: The use of Continuous Subcutaneous Insulin Infusion (CSII) is expected to improve glycemic control and to reduce hypoglycemia events. However, long-term beneficial results in glucose control are not always observed. We evaluated long-time glucose control and severe hypoglycemias in type 1 diabetic patients using CSII, without continuous glucose monitoring.Patients and methods: This was a retrospective study of adult type 1 diabetic patients...

Obesity is growing fast worldwide. Although environmental factors play a major role, endocrine dysfunction may contribute to the weight gain. We report an invasive macroprolactinoma diagnosed in obesity setting. A 35-year-old male was referred to our endocrine outpatient department due to grade 2 obesity (IMC 38.4 Kg/m2). His weight was increasing since the beginning of his professional activity at the age of 20 due to a sedentary lifestyle. On physical examination he had an h...
