Abstract

Juxtacortical osteosarcoma occurred on the right tibia and fibula of a 20-22 years old man found in a medieval period cemetery of Budapest. Macroscopic description: The tumor is located circumferentially on the midshaft of the tibia and fibula and appears cone-shaped. The lesion measured 160 mm in length and 3-5 mm in height. The surface of the tumor is irregular, rough, in some areas shows spicules. These spicules averaged 2-4 mm in length and 1-2 mm in diameter. The anterior and medial surface of the tibia is completely covered by osseous tumor. Radiography: The X-ray study demonstrates the medullary involvement, with mixed osteolytic and osteoblastic areas. Tumor infiltration of the cortex is also apparent as irregular rarefication and lytic lesions. In some areas a "sunburst " picture could be seen. The X-ray picture is characteristic for juxtacortical osteosarcoma. Microscopic examination: stereomicroscopy of specimens shows a sponge-like structure of the surface. The cortical bone is completely destroyed and deep cavities are seen between spiculous and gyrificated neoplastic bone. The spiculae are varied in length and thickness. Irregular bulky bone trabeculae demonstrating uncontrolled neoplastic reaction could be detected. By light microscopic examination severe destruction, osteolytic lesions are seen both in the cortical bone and in the cancellous bone in the peripheral parts of the tumors. Within the neoplastic bone only few remnants of the primary (normal) bone structure could be demonstrated. No reparative reactions were seen next to the osteolysis, the collagen fibers and lamellas are destroyed. Beside the destruction of original bone larger structures composed of irregular newly built nepotistic bone trabeculae can be detected. The newly formed trabeculae (spiculae) contain a tumorous ground substance (probably osteoid tissue) with few collagen fibers, and these areas are covered with a thin bony lamella. In some areas the neoplastic structures are in intimate contact with the original cancellous bone remnants. Immunohistochemistry: Both the osteosarcoma and chondrosarcoma show osteoid and bone neoformation while in the chondrosarcoma type II collagen could also detected. By immunohistochemical reactions no type II and III collagen, only type I collagen reaction was positive. This means that no cartilaginous tissues were present in the tumor. Scanning electron microscopy of these specimens shows sponge-like structures. The tumor reveals irregular trabecular and spicular texture, the spicules are various in diameter and in some spiculae rounded deposits attached to the surface. In our case we found typical radiological and histological picture of the juxtacortical osteosarcoma.
