Introduction: Bilateral adrenal masses may appear in the context of metastatic disease, adrenal congenital hyperplasia, primary tumors or infections, among others. Primary adrenal lymphoma is rare, accounting for approximately 1% of cases of non-Hodgkin lymphoma. Clinical case: 47-year-old woman, with a history of erythema nodosum and left hemithyroidectomy in the context of benign nodular disease. She presented with persistent fever and tiredne...

Introduction: Hypopituitarism is a rare diagnosis that is mainly due to primary pituitary neoplasms and their treatment. There are rarer causes such as hemorrhage/ischemia, traumatic brain injury, infections and infiltrative lesions. Clinical case: We herein present an 18-year-old male patient diagnosed with acute promyelocytic leukemia at the age of 14, with no evidence of central nervous system invasion in several lumbar punctures during his follow-up....

Turner’s Syndrome is one of the most common chromosomal abnormalities found in 1 in 2500 live female births. Y chromosome material is detected in up to 6% of patients by karyotype, but with new technologies (DNA analysis), Y chrmosome sequences have been reported in 60% of patients. The presence of Y material has been associated with virilization and with the development of gonadal neoplasia.Aim: Determine the frequency of Y chromosome sequences in ...

Objectives: To evaluate changes in gonadotrophins, total (TT) and free (FT) testosterone, SHBG, insulin and c-peptide levels during weight lost after bariatric surgery.Material and methods: Seven (n=7) patients submitted to bariatric surgery for treatment of severe obesity were followed-up over time. Before surgery mean age was 32,857 (19-56) years old, mean weight was 170,571 kg (± 37,362) and mean BMI was 58,824 kg per m2(± 14,...

Introduction: Differentiated thyroid cancer (DTC) is rare in the paediatric population when compared to adults. Paediatric patients often present with advanced disease at diagnosis, characterized by multifocal disease, heightened lymph node involvement, and distant metastasis. Additionally, they face a higher risk of post-operative complications in comparison to adults. Despite that, paediatric DTC exhibits an excellent prognosis.Methods: A retrospective...

Introduction: Adrenocortical carcinoma is a rare type of cancer that usually has a dismal prognosis. The concurrent hormonal excess of some of these tumours can have an additional negative impact on patients´ morbidity and mortality.Clinical Case: We present the case of a 57-year-old woman diagnosed with stage IV adrenocortical carcinoma, with liver and bone metastasis, and associated ACTH-independent Cushing syndrome and hyperandrogenism. The patie...

Introduction: Pancreatic neuroendocrine tumors (PNETs) originate from neuroendocrine islet cells and can therefore secrete several neuropeptides. Multiple and secondary hormone secretion have been described in a minority of cases, mostly with advanced disease, and it has been hypothesized that this complex secretion pattern can serve as a marker for tumor behavior.Case report: Male patient, 69 years old, diagnosed with a glucagonoma with pulmonary and he...

Background: Klinefelter syndrome is the most common sex chromosome abnormality causing primary hypogonadism and affects approximately 1 to 2.5 per 1000 males. However, other rarer sex chromosomal abnormalities have been associated to testicular dysfunction.Clinical Case: A thirteen-year-old male was referenced to Pediatric consultation due to obesity starting around age four. Perinatal background: maternal gestational diabetes controlled with diet and 10...

Introduction: The prevalence of Transgender individuals seeking gender affirming hormone therapy (GAHT) has been increasing. This therapy has been known to be highly effective in the treatment of gender dysphoria and enhancing mental health in this population.Aim: To evaluate the overall impact of GAHT on self-esteem, well-being and social/familial relations in the Portuguese adult transgender populationMethods: Cross-sectional stu...

Tc-99m sestamibi (MIBI) imaging is able to localize parathyroid adenomas/carcinomas in patients with primary hyperparathyroidism. Brown tumours are one of the skeletal manifestations of long standing hyperparathyroidism and its incidence has been reported to be 3%. Radiological features of these tumors may mimic bone metastasis. There are only a few reports showing brown tumours uptake in the whole-body Tc-sestamibi scan.We report a 72-year-old female wi...
