術後性上顎嚢壁にみられた石灰化物の観察

Light and scanning electron microscopic observations and electron probe microanalysis were carried out on granular calcified bodies that appeared in the wall of a postoperative maxillary cyst in a 59-year-old man. The granular bodies, stained slightly with hematoxylin, were scattered in the cyst wall. They reacted positively to von Kossa\u27s stain indicating calcification. Based on scanning electron microscopic observation, secondary electron images revealed them to be compact bodies, and they appeared as light spots in composition images. Electron probe microanalysis revealed that the bodies were ccomposed mainly of calcium and phosphorus. Some of the large bodies had a membranous calcification core, which was observed especially in von Kossa\u27s stained specimens. Therefore, we believe that these calcification core must be generated cell debris, cell membrane, nuclear membrane or subcellular organelles
