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.

Pheochromocytoma is a catecholamine-secreting tumor that arises from the medullary chromaffin cells but can rarely be extra-adrenal in origin. We present a case of a 16-year-old female patient with uncontrolled hypertension, despite being on lisinopril and metoprolol, and associated left-sided chest pain, recurrent headaches, and an unintentional weight loss of 10 pounds in one month. Laboratory work-up showed a markedly elevated plasma metanephrine level of 4463.

Pheochromocytoma is a rare tumor originating from the adrenal gland, characterized by the secretion of catecholamines. Due to the risk of hypertensive crises associated with catecholamine release, surgical procedures in pheochromocytoma patients are risky. In this case report, laparoscopic appendectomy for acute appendicitis in a patient who has pheochromocytoma will be presented.

Incidental adrenal masses are frequently detected due to the extensive use of cross-sectional imaging, with about 3% to 7% of adults estimated to have them. Paragangliomas and pheochromocytomas (PPGL), rare tumors originating from paraganglia tissues, including the adrenal medulla, continue to be imaging mimics, necessitating a multimodal approach for accurate diagnosis. We report a case of 72-years male presenting with intermittent pain abdomen for the past 1 year.

Endolymphatic sac tumors (ELSTs) are rare, slow-growing, and locally aggressive neoplasms that originate from the epithelial lining of the endolymphatic duct and sac. These are characterized by their infiltrative growth pattern and the potential for local destruction of surrounding structures, including the inner ear and temporal bone. We report a case of an incidentally diagnosed sporadic ELST.
