title: A method for decalcification with citric acid.
abstract: Psammoma bodies and small calcifications are frequently seen in a wide variety of tissues. These deposits of calcium salts render tissues difficult to section. Conventional decalcification alters the tissues; consequently it is not advisable to decalcify tissues containing only small calcium deposits. A simple and rapid method to remove small amounts of calcium salts using citric acid alone is described. This method does not alter the antigenic properties of the substances studied.
