AbstractPheochromocytoma is a rare catecholamine-producing tumor of the adrenal gland. Patients with known pheochromocytoma undergoing surgery require preoperative treatment with alpha-blockers to reduce the risk of intraoperative complications related to catecholamine release. If undiagnosed, pheochromocytoma can lead to life-threatening surgical complications. We report the case of a patient with a suspected solid pseudopapillary neoplasm in the pancreatic tail, for whom pancreatoduodenectomy was scheduled. However, shortly after abdominal incision, hypertensive crisis developed and was followed by severe hypotension requiring intravenous vasopressors, which prompted discontinuation of the operation. Further diagnostic evaluation revealed marked elevations in urinary excretion of methylated catecholamines and suggested that the tumor was in fact a pheochromocytoma extending from the left adrenal gland. After preoperative treatment with doxazosin, the patient underwent lateral transperitoneal laparoscopic adrenalectomy, with no major complications and an uneventful postoperative course. The pathological report confirmed a diagnosis of pheochromocytoma. Due to the potential for life-threatening surgical complications in patients with pheochromocytoma not treated preoperatively with alpha-blockers, this tumor type should be included in the differential diagnosis of abdominal tumors of unknown origin.

Adrenal Cortical Cells

Adrenal steroids are normally synthesized from acetyl coenzyme A via cholesterol. Cholesterol is also shown to enter the adrenal gland and to be localized in the lipid droplets of the adrenal cortical cells. Both pregnenolone and progesterone act as intermediates in the conversion of cholesterol into steroid hormones. During pregnancy an increased level of plasma cholesterol is known to be associated with an increase of the adrenal corticoid and progesterone. The present study is designed to demonstrate whether the adrenal cortical cells show any dynamic changes during pregnancy.

Microscopic Evidence

Within the last few years, adrenal cortical tumors with features concordant with the diagnostic criteria attributed to oncocytomas have been reported. To date, only nine reported cases exist in the literature. This report is the tenth case presentation of a presumptively benign neoplasm of the adrenal gland with a rare differentiation. Oncocytomas are well recognized benign tumors of the thyroid, parathyroid, and salivary glands and of the kidney. Other organs also give rise to these types of tumors, however with less frequency than the former sites. The characteristics generally used to classify a tumor as an oncocytoma include the following criteria: the tumor is 1) usually a solitary circumscribed mass with no gross nor microscopic evidence of metastasis (no tissue nor vascular invasion), 2) fairly bland in terms of mitotic activity and nuclear morphology, and 3) composed of large eosinophillic cells in which the cytoplasm is packed full of mitochondria (Figure 1).

Adrenergic Blocking

SummaryIntravenous injection of E. coli endotoxin (ETX), of adrenaline (AD) or of carbamylcholine (CBCH), caused fibrinolytic activity (FA), directly detectable on plasminogen-rich fibrin plates, to appear in the plasma of the rat. Adrenodemedul- lation abolished responses to ETX or CBCH, but enhanced those to AD. Rats given ETX exhibited marked hypotension, followed by a compensatory phase of normotension abolished by adrenodemedullation and significantly attenuated by phenoxy- benzamine, an a-adrenergic blocking agent which however failed to block FA caused by either ETX or AD. Aspirin, but not indomethacin, inhibited FA evoked by ETX, AD or CBCH. These results suggest that FA evoked by ETX in the rat is caused by AD released from the adrenal gland and does involve the fatty acid cyclooxygenase system.
