title: Histopathology and ultrastructure of tumours and tumour-like lesions of bone.
abstract: The monograph summarizes the most important data and experience based on the clinicopathological analysis, histological and histoenzymatic examinations of more than 1000 primary tumours and 400 tumour-like lesions of bones. The diagnosis of them has been based on the WHO classification of bone tumours which appeared to be the best in meeting the needs of diagnostic practice. However, in our collection of cases also occurred such cases which did not fit into the WHO diagnostic scheme. They included lesions the separate existence of which could be proved only recently or has remained the matter of discussion, such as periosteal osteosarcoma, clear-cell and dedifferentiated chondrosarcoma, malignant fibrous histiocytoma, the so-called parachordoma, resorptive giant-cell granuloma, reactive periostitis of tubular bones of hands and feet, and the tibial lesion reminiscent of cementifying fibroma. In the majority of types of the tumours and tumour-like lesions of bones electron microscopical examination was carried out (203 cases), the results of which are presented here in a considerable extent. On the one hand, electron microscopy facilitated the diagnosis in some cases, and, on the other hand, it proved as extremely important in solving the problems of histogenesis of some of the lesions.
