Extra-adrenal pheochromocytomas are rare neuroendocrine tumors originating outside the adrenal glands and can pose significant diagnostic challenges due to their variable presentations. This report highlights a case of an extra-adrenal pheochromocytoma masquerading as a pancreatic head malignancy. We underscore the importance of considering extra-adrenal pheochromocytoma in the differential diagnosis of pancreatic masses, particularly when biochemical or clinical features suggest catecholamine excess. Early recognition and appropriate management are crucial to avoid unnecessary interventions and improve patient outcomes.

Background: Several cases of pheochromocytoma presenting with hypertensive crises after anesthesia induction, possibly caused by rocuronium injection, have been reported. Rocuronium has two compositions: rocuronium bromide (RB) in sodium acetate hydrate/acetic acid buffer solution (acetic acid vehicle) and RB in glycine/hydrochloric acid buffer solution (hydrochloric acid vehicle). This study assessed the effect of rocuronium composition on the release of catecholamine from PC-12 rat adrenal pheochromocytoma cells.

Background: Hypertension in young adults is often due to secondary causes, and investigating these can be resource-intensive. This study aimed to identify clinical and biochemical markers that could suggest secondary hypertension in individuals under 40 years.
Materials And Methods: A 6-year retrospective observational cohort study included 207 young adults with hypertension who were assessed for secondary causes such as hyperthyroidism, primary aldosteronism, Cushing's syndrome, pheochromocytoma, and renovascular disease.
Pheochromocytoma (PHEO) currently is considered to be malignant due to metastatic potential. One of the most common familial forms of PHEO is multiple endocrine neoplasia syndrome (MEN) type 2. The penetrance of PHEO in MEN2 syndrome is up to 50% of cases.
