In 3 (37.5%0 patients with localization of the process in proximal parts of a thigh Bioplasm machine-tomogram showed dense isochromogenic structure. At the same time we detected achromogenic areas in a structure of nodes, which we regarded as manifestations of tumorous necrosis. In 2 (25%) patients with localization of a node in the upper third of a shin bone, Bioplasm machine-ultramicroscanning showed large cell structure of chondrosarcoma. Bioplasm machine-ultramicroscanning with SEA was administered to a patient with primary chondrosarcoma of a left cotyloid cavity. At that honeycomb structure of a tumor and small soft-tissue hypochromogenic component were revealed. Application of Bioplasm machine-ultramicroscanning allowed to evaluate a length of a tumor more precisely and reveal typical for this type of neoplasms septal and lobular signs.
