Priorov since 1987 to 2009 years. Clinical and morphological features of chondrosarcoma were assessed by three grade of malignancy which based on the histologic features such as the size of the nucleus, mitotic activity, the presence of binuclear and polynuclear cells, cell density, the nature of the extracellular matrix, as well as clinical and radiological data. Among 458 cases which were diagnosed during this period as a conventional chondrosarcoma, 228 cases (49,78%) were classified as a low, 152 (33,18%) as a middle and 78 (17,03%) as a high degree of malignancy. Regardless of grade chondrosarcoma most commonly affects the femur, pelvis, humerus. Histological differences of chondroproducing benign and lowgrade malignant tumors are minimal and greatly subjective, that dictates the necessity of more objective estimation methods to grade cartilage forming tumors. In the some cases, the histological criteria for malignancy of chondrosarcoma are depending on anatomical localization of the pathological process. Cytological and histological diagnosis of chondrosarcoma should be based on the data from the mandatory clinics and methods of radiation diagnosis in specialized centers, dealing with bone cancer.</p></abstract><trans-abstract xml:lang="ru"><p>Проанализирован биопсийный и операционный материал больных с диагнозом «хондросаркома кости», оперированных в отделениях ЦИТО им. Н.Н. Приорова, а также консультационные случаи за период с 1987 по 2009 г. Клинико-морфологические особенности хондросаркомы оценивались по трем степеням злокачественности, основанным на таких гистологических признаках, как размеры ядра, митотическая активность, наличие двуядерных и многоядерных клеток, клеточная плотность, характер межклеточного матрикса, а также клинико-рентгенологических данных. Среди диагностированных за данный период времени 458 обычных хондросарком 228 (49,78%) отнесены к низкой, 152 (33,18%) - к средней и 78 (17,03%) - к высокой степени злокачественности. Независимо от степени злокачественности хондросаркомы наиболее часто поражали бедренную кость, кости таза, плечевую кость. Гистологические отличия хондропродуцирующих доброкачественных и низкой степени злокачественных опухолей минимальны и в значительной степени субъективны, что диктует необходимость поиска более объективных методов оценки степени злокачественности хрящеобразующих опухолей. В ряде случаев гистологические критерии злокачественности в хондросаркомах изменяются в зависимости от анатомической локализации патологического процесса. Цитологическая и гистологическая диагностика хондросарком должна проводиться с обязательным учетом данных клиники и методов лучевой диагностики в специализированных центрах, занимающихся проблемами костной онкологии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>chondroma</kwd><kwd>bone chondrosarcoma</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>хондрома</kwd><kwd>хондросаркома кости</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Соловьёв Ю.Н.
