A rare case of a non-secretory medullary thyroid carcinoma

Rita Elvas Ana , Couto Joana , Martins Raquel G. , Santos Jacinta , Martins Teresa , Rodrigues Fernando

Introduction: Medullary thyroid carcinoma (MTC) is a rare neuroendocrine tumor (1-2% of all thyroid carcinomas), which arises from calcitonin-producing C cells. Calcitonin (CT) and carcinoembryonic antigen (CEA) are used as tumor markers in the follow-up of patients with MTC. Non-secretory forms of MTC are very rare, accounting for less than 1% of the cases.Case Report: A 53-year-old man underwent left thyroid lobectomy for a 1.1 cm thyroid nodule subjec...

A challenging case of sheehan syndrome

Rita Elvas Ana , Vieira Ine s , Melo Miguel , Rodrigues Di rcea , Gomes Maria Leonor , Paiva Isabel

Introduction: Sheehan Syndrome (SS) is a cause of hypopituitarism resulting from postpartum pituitary infarction. Its frequency is decreasing worldwide, particularly in developed countries due to advances in obstetric care. Case report: A 50-year-old female patient was admitted to the emergency department with complains of progressive pain in the lower hemithorax and abdomen. She also referred constipation, weight gain and asthenia. The initial laborator...

Hypopituitarism in adults - the importance of clinical suspicion

Rita Elvas Ana , Lavrador Mariana , Melo Miguel , Barros Lui sa , Gomes Maria Leonor , Paiva Isabel

Introduction: Hypopituitarism is a rare entity that can have different aetiologies. Symptoms are usually progressive and non-specific; therefore, many patients are underdiagnosed and untreated. We present a clinical case of a patient presenting septic shock, hyponatremia and central hypothyroidism.Case report: A 46-year-old man was admitted in ICU for septic shock of unknown origin and multiorgan failure. Hormonal profile showed central hypothyroidism, p...

Is there a role of measuring preoperative serum thyroglobulin?

Rita Elvas Ana , Marques Bernardo , Couto Joana , Raquel G. Martins , Santos Jacinta , Martins Teresa , Rodrigues Fernando

IntroductionThe measurement of serum thyroglobulin (Tg), a glycoprotein produced exclusively by follicular thyroid cells, is an important tumour marker used in the follow-up of patients with differentiated thyroid carcinoma (DTC) and residual or recurrent disease. However, its role as a screening tool before thyroid surgery is not yet defined, as benign conditions can result in its increase.ObjectiveThe aim o...

Two rare cases of Riedel’s thyroiditis

Martins Fernandes Andreia , Rita Elvas Ana , Couto Joana , Martins Raquel G. , Santos Jacinta , Martins Teresa , Rodrigues Fernando

Introduction: Riedel’s thyroiditis (RT) is a rare chronic inflammatory disease characterized by a dense fibrosis that replaces normal thyroid parenchyma. The most common manifestation is a stony hard thyroid mass, commonly associated with compressive symptoms. Histological confirmation is essential for diagnosis and the main differential diagnosis is the anaplastic thyroid cancer. The management is challenging and there is no agreed standard treatment, since only a few ca...

Anomalous uptake of 131-iodine in an endometriosis cyst

Rita Elvas Ana , Marques Bernardo , Couto Joana , Raquel G. Martins , Santos Jacinta , Martins Teresa , Oliveira Sofia , Rodrigues Fernando

IntroductionRadioiodine whole-body scintigraphy plays an important role in the follow-up of patients with differentiated thyroid carcinoma (DTC), as it is highly accurate in detecting thyroid residues and recurrent disease. Unusual 131-iodine uptake outside the thyroid bed and areas of physiological uptake is strongly suggestive of distant metastasis. However, uncommon uptake may occur and lead to diagnostic errors.Case report<...

Introduction: Adrenocortical carcinoma (ACC) is a rare entity, usually associated with a poor prognosis. There are still many areas of uncertainty regarding its approach.Methods: A Portuguese ACC register was established in 2020, including information from 24 endocrine centres. Kaplan-Meier was used to calculate overall survival and recurrence; log- rank test to assess survival and progression free survival (PFS) differences between groups; cox-regressio...
