Differentiating Benign from Malignant Adrenocortical Tumors by a Single Morphological Parameter-a Clinicopathological Study on 837 Adrenocortical Neoplasias.

The morphological differentiation between benign and malignant adrenocortical tumors is an ongoing problem in diagnostic pathology. In recent decades the complex scoring systems have been widely used to calculate the probability of malignancy in adrenocortical tumors on the basis of a variety of histomorphological parameters. We herewith present a substantially simplified method to diagnose adrenocortical carcinoma by a single histomorphological parameter on a consecutive series of more than 800 adrenocortical tumors.

Liver steatosis in pre-transplant liver biopsies can be quantified rapidly and accurately by nuclear magnetic resonance analysis.

Donor livers marginally acceptable or acceptable according to extended criteria are more frequently transplanted due to the growing discrepancy between demand and availability of donor organs. One type of marginally acceptable graft is a steatotic donor liver, because it is more sensitive to ischemia-reperfusion injury. Thus, quantitative assessment of steatosis is crucial prior to liver transplantation.
