Introduction: The presence of undetectable serum levels of stimulated thyroglobulin (Tg) with negative imaging tests is the criterion used to define remission in low-risk differentiated thyroid cancer (DTC). Most guidelines recommend 131-I ablation after thyroidectomy to remove any possible residual thyroid tissue. Our aim was to know how often undetectable Tg levels are achieved before ablation to avoid unnecessary radiation treatments.Patients and meth...

Introduction: Pancreatic ACTHomas have a poor prognosis with severe and rapidly progressive clinical courses, influenced by hypercortisolaemia thus whenever possible, control of the cortisol levels should be obtained to reduce complications. We report the use of adrenal embolisation in a case of a life threatening paraneoplastic Cushing.Case: A 51-year-old woman with a negative past medical history complained of general weakness. Cushing’s syndrome ...

Introduction: Pheochromocytomas are a rare catecholamine secreting tumours that can mimic numerous stress-associated disorders, such as Takotsubo cardiomyopathy, or transient left ventricular apical ballooning which is brought on by an acute coronary vasospasm due to an excessive sympathetic stimulation.Case ReportA 68-year-old woman, with previous medical history of hypertension and type 2 diabetes, who was on 30 units of isuline ...

Introduction: TSHomas are rare TSH producing tumors, whereas chronic autoimmune thyroiditis is a frequent condition. Patients with TSHoma are characterized by increased circulating levels of peripheral thyroid hormones, but when a chronic autoimmune thyroiditis is associated, they may be normal or low, making the diagnosis challenging.Case report: A 55 year-old woman, with previous medical history of obesity and impaired fasting glucose, was diagnosed of...

Introduction: Phaeocromocytomas are a rare catecholamine secreting tumours that can present in multiple ways. The classic triad of symptoms consists of episodic headache, sweating, and tachycardia. Most patients do not have the three classic symptoms. Sustained or paroxysmal hypertension is the most common sign. Among less common symptoms and signs constipation has been described and few cases of megacolon and phaeochromocytoma have been published.Case r...
