Background: Systematic exploration for anterior pituitary deficiency in patients harboring pituitary microadenomas is not well defined. So far, little is known on the involvement of pituitary function in clinically non-functioning pituitary microadenomas (CNFPM).Objective: To evaluate the prevalence of anterior pituitary insufficiency, defined as at least one hormonal deficiency, in patients diagnosed of CNFPM.Patients and methods:...

Objetive: To assess the clinical features of incidental clinically non-functioning pituitary adenoma (NFPA) and to analyze its natural history.Methods: A multicenter retrospective study in patients with NFPA followed-up from 1992 to 2015 was performed.Results: Fifty-seven patients were studied (29 women (50.9%); age 55.8±16.7 years. 43.9% were older than 60 years, 40.3% belonged to the age group of 40–60 years and 15.8% w...

Introduction: Hyperprolactinemia has been associated with several metabolic abnormalities both in glucose homeostasis, insulin sensitivity, and in lipid profile. Moreover, it has also been reported that many of them seem to improve after normalizing serum prolactin (PRL) concentrations.Objective: To study serum glucose, cholesterol and triglyceride in men with prolactinoma before and after chronic treatment with cabergoline.Patient...

Objective: To assess clinical outcome after pituitary surgery in patients nonfunctioning pituitary adenomas (NFPA) surgically treated in the past 3 decades in three tertiary referral hospitals.Methods: A multicenter retrospective study on clinical and pathological characteristics, treatment patterns, and outcome in patients with NFPA periodically followed up in specialized neuroendocrinology units who underwent surgery in the period 1982–2015 was pe...

Background: In some patients with adrenal tumors cortisol regulation may be under the control of abnormal or ectopic hormone receptors. The objective of this study is investigate the presence of these aberrant receptors in subjects with adrenal incidentaloma and biochemical criteria of subclinical hypercortisolism.Patients and methods: We studied seventeen patients with adrenal incidentalomas, ten patients with a unilateral tumor (age 48–70, M/F: 4/...

Aims: To evaluate the clinical features and long-term therapeutic outcome of giant prolactinoma (gPRLoma) in men and to compare them with those of a group of male patients with non-gPRL macroprolactinomas (non-gPRLomas).Patients and methods: A retrospective and multicenter study of gPRLomas in men diagnosed in a 20-year period was performed. Clinical data and treatment outcome were registered. The diagnosis of gPRLoma was established when the maximal tum...

Introduction: Doege-Potter syndrome (DPS) is a rare paraneoplastic syndrome consistent in non-islet-cell tumor hypoglycemia associated with solitary fibrous tumor (SFT). Pathogenesis of hypoglycemia has been attributed to the production of insulin-like growth-factor-2 (IGF-2) by tumor cells. We report two DPS patients with metastatic extrapleural SFT.Case 1: A 42-year-old man with SFT of the mesocolon that had been operated in 2010, presented with metast...

Background: Pituitary adenomas (PA) and pheochromocytomas/paraganglioma (pheo/PGL) can occur in the same patient due to coincidence or of shared pathogenesis. There is evidence that, at least in some cases, classical pheo/PGL predisposing genes, may also play a role in pituitary tumorigenesis. A new condition called ‘the three P Association’ (3PAs) for the combination of PA with pheo/PGL has been recently described in patients with or without succinate dehydrogenase ...

Introduction: Pheochromocytomas (Pheo) may appear sporadically (SPheo) or as an autosomal dominant inherited disease, named as familial PHEOs (FPheo). The latter are present in younger patients, and usually with multiple tumors, but may occur in patients with apparently simple sporadic tumors with no other syndromic features.Material and methods: Clinical data of all consecutive patients underwent surgery for Pheo over 35 years in two tertiary referral c...

Background: Individuals with neurofibromatosis type-1 (NF1) carry an increased risk of pheochromocytoma (PHEO). Detection strategy is unknown but most experts recommend screening if hypertension develops.Objective: Report the characteristics of PHEO in patients with NF1 (NF1 group) and compare them with non-NF1-associated PHEO (non-NF1 group).Methods: Retrospective cohort study of patients undergoing PHEO resection in two Spanish t...
