Abstract
In a series of ten patients a total of 14 pheochromocytomas have been removed. All the tumors were located in the adrenal glands, except for one situated in the organ of Zuckerkandl. In one man two tumors were removed from the right adrenal gland with an interval of five years. Bilateral pheochromocytoma was found in three of five young women. In two of them the second tumor appeared as late as seven and ten years respectively after removal of the first. A woman got her second pheochromocytoma during pregnancy. She was treated with alphamethyldopa and went through an uncomplicated delivery. A fortnight later the tumor was removed. Two men suffering from “diabetes mellitus” were ultimately diagnosed as having pheochromocytoma. Removal of the tumor led to cure. The same applied to two young women suffering from “acute” and “chronic nephritis” respectively. In two instances the urinary output of catecholamines was normal, while the excretion of metabolites was significantly elevated. In another instance the excretion of vanillin mandelic acid was normal, whereas the remaining biochemical outputs were increased.
