Malignant peripheral nerve sheath tumors (MPNSTs) have rarely been reported to occur in the adrenal gland and all of the reported cases were associated with neurofibromatosis, pheochromocytoma or ganglioneuroma. We present here a case of MPNST in the bilateral adrenal glands without any history of neurofibromatosis or combined tumor. Histologic examination showed the tumor cells had a spindle t...

Abstract Background Pheochromocytoma is a rare tumor originating from the adrenal medulla, and surgical removal main treatment. We report case of large size pheochromocytoma that was removed laparoscopically without preoperative blockade alfa adrenergic receptors. Case presentation A 58-y-old woman referred to our center with incidentally found 7 cm right mass. She did not have any history hype...

A 26-year-old male presented to the emergency department complaining of obstipation, severe headache and abdominal pain. An autopsy revealed bilateral pheochromocytoma and acute myocardial infarction. The tumor cells showed positive immunoreactivity of both chromogranin A and synaptophysin and were negative for adrenocortical markers such as SF-1, c17, scc, 3-HSD as well as SDHB, suggesting a ...

Chromaffin granule transmitters such as chromogranin A and catecholamines have been used in the diagnosis of pheochromocytoma, but the diagnostic and prognostic value of chromogranin A have not been explored in malignant pheochromocytoma. We evaluated these transmitters in patients with pheochromocytoma (n=27), both benign (n=13) and malignant (n=14). Patients with benign pheochromocytoma were ...

the intraoperative care of pheochromocytomas can be difficult and lead to serious complications. we present a case of a 46 year-old female undergoing laparoscopic resection of pheochromocytoma, who was scheduled for surgery with phenoxybenzamine and amlodipin. under general anesthesia cardiovascular stability was achieved by peritumoral infiltration of lidocaine during resection.

Congenital adrenal hyperplasia (CAH) patients with testicular adrenal rest tumors (TARTs) with testicular enlargement present a serious diagnostic challenge. According to the data TARTs are usually benign. They are rare, resulting in paucity in the medical literature regarding their pathological features. We report a case of bilateral synchronous mass-forming TARTs with marked cytological and n...

Pheochromocytomas are tumors of the neural crest-derived chromaffin cells. The hallmark of this rare and fascinating neoplasm is the synthesis and secretion of catecholamines in an unregulated and potentially life-threatening manner. Most pheochromocytomas produce an abundance of norepinephrine. Epinephrineor dopamine-secreting pheochromocytomas are less common.[1] Pheochromocytomas can also be...

Conn's syndrome, an aldosterone producing adenoma, is a surgically curable cause of primary aldosteronism, classically treated by unilateral adrenalectomy. With the advent of laparoscopic surgery in the recent decade, laparoscopic adrenalectomy is currently accepted as the gold standard of treatment for Conn's syndrome. Cortical sparing adrenalectomy is especially an ideal operation for patient...
