Introduction: The usefulness of acute octreotide suppression test (OST) in the selection of patients with acromegaly for chronic somatostatin analogues (SA) treatment is still controversial.Aim: To investigate the predictive value of OST for long-term responsiveness to long-acting SA.Materials and methods: Retrospective study of 25 drug-naive patients (13 males) with active acromegaly, subjected to an OST (hourly serum GH concentra...

Introduction: Pheochromocytoma is an uncommon tumor. Non-classical forms can make diagnosis difficult and delay correct management strategies.Case report: A 20-years old caucasian male presented to the emergency room with unproductive cough, fever and tiredness for 7 days. He was eupneic, afebrile, BP 176/115 mmHg, 104 bpm with inspiratory crepitations in the left lung base. Leucocyte–14.1×109/l (N 70%); platelets – 659×10<...

Introduction: Giant prolactinomas are rare pituitary tumours, more frequently found in men (9:1), defined by an unusually large size (>4 cm), significant extrasellar extension and prolactin levels above 1000 ng/ml. Although dopamine agonists (DA) are the first-line treatment, combined therapy with DA and surgery, or rarely radiotherapy, may be necessary particularly when tumour volume control is not achieved.Case presentation: A 60-year-old woman, wa...

POEMS syndrome characterized by polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy and skin changes is a rare disease that usually presents in the 6th decade. We report a case of a young male in whom the presenting manifestations were mandibular mass, adrenal insufficiency and peripheral polyneuropathy. Clinical case: A thirty-three year old man from Guinea-Bissau was admitted to our hospital with asthenia, weight loss, decreased tactile sensibility with pain ...

Introduction: Pituitary adenomas represent 95% of all sellar masses. Spindle cell oncocytoma (SCO), a rare histopathological entity (0.4% of all sellar tumours), clinically presents as a non-functional pituitary adenoma. According to WHO 2016 Classification of Tumours of the CNS it is a Grade l tumour, but prognosis remains uncertain since recurrence is frequently seen among the few cases reported.Clinical case: A 59 year-old man presented with progressi...

Introdution: Prolactinomas in men are rare and the majority are macroadenomas. Some studies suggest that these tumors in men have higher proliferative activity and aggressiveness indicating gender-specific differences in biological behavior. Dopamine agonists (DA) are considered first-line therapy.Material/methods: Retrospective analysis of male patients diagnosed with prolactinoma between 2005 and 2016. Age at presentation, clinical, hormonal and image ...

Introduction: somatostatin analogs (SSA) are largely prescribed in acromegalic patients, whether as adjuvant or primary therapy. Response is variable and seems dependent of histological subtype. Intensity T2 signal in MRI has been related to granulation patern and accordingly with response to SSA.Objective: To evaluate whether T2 MRI signal is correlated with effectiveness of SSAMaterial and methods: Retrospective analysis of acrom...

Introduction: Multiple Endocrine Neoplasia type 1 is an underdiagnosed autosomal dominant disorder, with inter and intrafamilial variability without a genotype-phenotype correlation.Case report: A young female (born in 1986) presented with galactorrhea and secondary amenorrhea in 2002, and investigation revealed a prolactinoma. Her brother (born in 1982) presenting gynecomastia and erectile dysfunction at age 21, was also diagnosed with prolactinoma. The...

Macroprolactin is a collective term for a heterogenous group of high molecular mass forms of prolactin with minimal bioactivity in vivo. Objective: to determine prevalence of macroprolactinemia (macroPRL) and clinical characteristics of patients with hyperprolactinemia (hyperPRL) who underwent assessment for macroPRL in Endocrinology outpatient clinic.Methods: We reviewed the medical records of 54 patients who were evaluated for macroPRL between...

Introduction: Bilateral macronodular adrenal hyperplasia (BMAH) is a rare aetiology of Cushing syndrome. Familial clustering suggests a genetic cause that was recently confirmed, after identification of inactivating germline mutations in armadillo repeat containing 5 (ARMC5) gene.Clinical case: A 70 years old female admitted due to femoral neck fracture in May 2014, presented central obesity, rubeosis and hypertension. Laboratory work up reveale...
