[Mesenchymal chondrosarcoma (clinico-morphological study)].
Mesenchymal chondrosarcoma was found in 11 out of 161 patients with chondrosarcoma of the bone. The assaultive nature of the disease is illustrated by the following data: the period between the manifestation of symptoms and the first visit to the doctor was 5.9 +/- 4.3 months; metastases were detected within 20.56 +/- 6.04 months and 8 patients out of 10 died within the first 5 years. Two histological structures were observed: those of the chondrosarcoma type and hemangiopericytoma-like structures formed of small atypical cells.
