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 ...

IntroductionTurner syndrome(TS) is characterized by complete/partial monosomy or by a structural defect in one of X chromosomes. Despite clinical hallmarks of short stature(SS) and gonadal dysgenesis(GD), phenotype is variable and related to underlying chromosomal pattern. Loss of the distal segment of the short arm of x-chromosome(Xp-), including haploinsufficiency of short stature homeobox-containing (SHOX) gene, is thought to be the main factor for gr...

Insulinoma, a rare neuroendocrine tumor (NET), is benign in more than 90% of cases. We present a review of patients diagnosed with insulinoma at our Department.Methods: Retrospective review of clinical records of patients diagnosed with insulinoma between 2011 and 2016.Results: Six female patients were diagnosed with insulinoma (age at presentation 30–66, follow-up: 0.25–3.25 years). Episodes of sweating, palpitations, tr...
