Adrenocortical nodules in post-mortem series. Development, functional significance, and differentiation from adenomas.
In 498 consecutive autopsy cases, the adrenal glands were light microscopically and morphometrically studied. 265 (53.7%) patients showed single or multiples nodules, 25 (5.0%) adenomas. The diameter of nodules was between 0.3 to 8.0 mm and that of adenomas between 3.2 to 28.0 mm. Clinically, 265 (36.5%) patients revealed arterial hypertension. 283 (63.5%) were normotensive. For the diagnosis of adenomas, the architecture and the cell structure were more important than the size of the tumor. Normotensive patients showed more often (55.%) nodules than hypertensive patients (52.8%). Adenomas were more frequently found in hypertensive patients. There was no correlation between age, sex and nodules, but adenomas were more frequently found in females. Normotensive patients exhibited mainly one nodule, whereas multiple nodules were found in hypertensive patients. In patients with nodules arteriosclerosis with intima hyalinosis was present in 184 (56.3%) cases, in patients without nodules in 81 (47.4%) cases. Our study clearly demonstrates that no correlation exists between the occurrence of adrenocortical nodules and age or hypertension. The etiology of adrenal nodules should be considered together with the arteriopathy.
