| Abstract: | After the reconstruction of the original parish church of the Moravian town of Kyjov in the latter part of the seventeenth century, human skeletal remains from the disturbed graves of the surrounding cemetery were gathered in a vault which was partially excavated in 1994. Among disarticulated bones of at least 106 individuals, a fragmented skull of a young male was found, with a massive outgrowth of bone on the right parietal, originally continuing fluently on the non-preserved frontal scale, on edges lifting the outer lamina. The inner lamina was covered less intensively by the bony growth. Radiography and CT scans showed a non-homogeneous structure, the inside being irregular and the outside granulated or radially striated. A metastatic lytic focus was detected in the same bone. Histology and SEM examination showed an uneven mineralization of the bone tissue, consisting of rough, thickened and irregularly spaced trabeculae, with cellular remains or mineralized matrix on the surface. The differential diagnosis took meningioma into consideration but the most probable diagnosis was osteogenic sarcoma, which is still infrequent in the palaeopathological record from the Old World and its localization in the cranial vault is very rare. © 1997 by John Wiley & Sons, Ltd. |
