Background: Tako-tsubo cardiomyopathy (TTC) is a non-ischemic condition manifested with a temporary weakening of the myocardium after an acute stress. The association between pheochromocytoma (PHEO) and TTC is rare and is attributed to catecholamine excess. We present a case of a young women with an atypical manifestation of PHEO.Clinical case: Patient, F, aged 37, known with multinodular goiter with hypothyroidism for several years, having paroxysmal hy...

Introduction: Pheochromocytomas (PHEOs) are tumors arising from medulla chromaffin cells. Their diagnosis is challenging due to a large clinical spectrum – from classical crisis to completely asymptomatic. Approximately 5.0–6.5% of adrenal incidentalomas are pheochromocytomas, and 8% of pheochromocytomas are completely asymptomatic, usually in a familial form.Aim: To compare biochemical and imagistic features of symptomatic/asymptomatic PHEOs.<...

Graves’ disease (GD) and Hashimoto’s thyroiditis (HT) are both autoimmune thyroid diseases. While transition from GD to hypothyroidism has been more frequently reported, conversion of hypothyroidism to GD is uncommon. We describe a series of 3 patients diagnosed with HT and hypothyroidism, treated with L-thyroxine (LT4), who developed persistent hyperthyroidism with increased thyrotropin receptor antibodies (TRAb) levels and, in two of the patients, Graves’ opht...

New possible pathogenic variants involved in pheochromocytomas and paragangliomasIntroduction: Pheochromocytomas and paragangliomas (PPGLs) are rare tumors of the chromaffin tissues that store and release catecholamines in excess. Most pheochromocytomas are sporadic, usually resulting in unilateral adrenal tumor, but 25–45% harbour a germline mutation.Aim: To describe new possible pathogenic variants (VUS) involved in PPGLs.</...
