title: [Ultrastructural characteristics of chondroblastomas].
abstract: The ultrastructure of chondroblastomas and two new ultrastructural peculiarities typical of the given form of tumours are described. Being typical but not constant these peculiarities may be an additional argument indicating that such cells may be regarded as chondroblastoma cells. The ultrastructure of these cells is similar to that of normal epiphyseal chondrocytes and differs from the ultrastructure of chondrosarcoma cells.
