Pheochromocytomas are neuroendocrine tumors that derive from sympathetic adrenomedullary chromaffin tissue and produce catecholamines. Due to the excess release of catecholamines, they can produce arterial hypertension, tachycardia, sweating, headache and a large number of other clinical manifestations secondary to the stimulation of α and β adrenoreceptors. Screening for pheochromocytoma is recommended in patients with paroxysmal, resistant or early-onset arterial hypertension, in cases with symptoms suggestive of catecholamine hypersecretion, patients with hereditary syndromes associated with pheochromocytomas, diabetes mellitus of atypical presentation and in adrenal incidentalomas with radiological characteristics not typical of adenoma (with > 10 Hounsfield Units on non-contrast CT).

Quantifying urinary catecholamines and metanephrines is essential for the clinical screening and diagnosis of neuroendocrine tumours. HPLC with electrochemical detection (HPLC-ECD) is commonly used for this type of analysis but requires extensive sample cleanup. Simple and rapid dilute-and-shoot LC-multiple-reaction monitoring (MRM)-MS assays have been developed for quantitating these analytes in urine but have not yet been validated according to the Clinical and Laboratory Standards Institute (CLSI) guidelines.

Background: Sweet's syndrome (SS) or acute febrile neutrophilic dermatosis is a dermatological illness that can be described by tender erythematous plaques or nodules and acute onset fever. The etiology is multifactorial and is not fully understood. SS is separated in three subclasses: classical, malignancy-associated, and drug-induced.

Adrenocortical carcinomas are rare but aggressive tumors that are frequently discovered as incidentalomas. Secretory tumors often lead to endocrine abnormalities, namely cushingoid features, virilization, or feminization. Non-functioning tumors, on the other hand, can be completely dormant with an insidious course or cause malaise, weight loss, abdominal pain, etc.

Paragangliomas, a type of extra-adrenal tumour, albeit rare, are dangerous due to their high metastatic potential and risk of hypertensive crisis from massive catecholamine release. It typically presents with sympathetic overdrive symptoms such as diaphoresis, headache, and palpitation, accompanied by substantially high plasma metanephrines level and mass on contrasted computed tomography abdomen and pelvis, whilst some are found incidentally. In this report, we discuss a case of an extra-adrenal lesion located near susceptible major structures with extensive vascularisation, in a patient with near-death experience.
