Introduction: Pituitary surgery is currently considered the preferred treatment for Cushing’s disease (CD) and achieves remission in 55–85% of patients. Cortisol falls quickly after surgery, so that early post-operative cortisol level has been used as predictor of remission. There’s no agreement about optimal timing for cortisol measurement, with wide variability between centres.Objective: To assess the value of early post-operative serum ...

Introduction: Cushing’s disease (CD) is characterised by pathologic hypercortisolism caused by an ACTH-secreting pituitary adenoma. The primary modality for definitive treatment is pituitary surgery. The rarity of CD has made it difficult to establish reliable predictive factors of outcomes.Aim: Assessment of clinical, hormonal, radiological, surgical and histological findings as predictors of remission and relapse of CD.Metho...

Introduction: Atypical pituitary adenomas have higher risk of aggressive behaviour in particular by the higher growth, local invasion and high risk of recurrence after surgery. In acromegaly the resistance to somatostatin analogues may be another manifestation of these adenomas since higher levels of Ki-67 are associated with poor response to therapy.Case report: A 41-year-old woman presented to our consult with history of headaches, growth of the hands,...

Introduction: Cushing’s disease (CD) is a rare endocrine disorder characterized by endogenous hypercortisolism, which is associated with metabolic and psychiatric disorders. It is essential to understand the impact of normalization of serum cortisol in the evolution of these comorbidities.Aims: To evaluate the evolution of metabolic and psychiatric disorders after biochemical control of hypercortisolism in patients with CD.Met...

Introduction: Cushing’s disease (CD) presents a marked female preponderance, with a female-to-male ratio of 3–8:1, but whether this skewed gender distribution has any relevance to the presentation and outcomes of CD is not well understood.Aim: To evaluate sex-related differences in the presentation of CD, as regards: biochemical indices of hypercortisolism; complications of disease and outcomes.Methods: Observational, ret...

Introduction: Cushing’s Disease results of corticotrophin (ACTH) hypersecretion from pituitary which increases cortisol production. WHO classified pituitary tumors as typical adenoma, atypical adenoma and carcinoma. Diagnostic criteria for an atypical adenoma include invasive growth, elevated mitotic index, Ki-67 labeling index greater than 3% and extensive p53 immunoreactivity.Case Report: Sixty-eight years-old man presented to our consult with his...

Introduction: Germ cell tumors (GCTs) are classified as extragonadal if there is no evidence of a primary tumor in the gonads. They typically occur in the midline structures. Newly diagnosed adult cases of pituitary or pineal glands germinomas are very rare since most of the cases are diagnosed in the mid teens, presenting 14:1, on behalf of the male gender. The estimated incidence of this tumor in western countries is between 0.4–3.4%, being more frequent in the Asia.</p...

Introduction: Pituitary macroincidentalomas are rare, being found in only 0.2%–0.3% of the patients that undergo imaging studies for an unrelated reason. The majority of them are non-functioning adenomas.Case Report: Woman, 77 years-old, with type 2 diabetes mellitus, hypertension and primary hypothyroidism. She was referred to Endocrinology due to a pituitary incidentaloma (18 mm of maximal diameter, with extension to the cavernous sinus and to the...

Introduction: People with intracranial organic lesions, including pituitary tumours, may manifest initially as a psychiatric disorder, such as depression, emotional disturbance, anxiety, apathy, neurobehavioral disturbance, cognitive dysfunction and personality disturbance.Case Report: A male patient 45 years old was sent to the Department of Endocrinology of São João Hospital due to a pituitary macroadenoma. The patient referred asthenia, musc...
