OBJECTIVE To investigate the biological behavior of classical and atypical osteoblastomas in comparison to osteosarcomas. METHODS Based on histological parameters, 30 osteoblastomas were subclassified as classical osteoblastomas (23/30) or atypical osteoblastoma (high cellularity, prominent blue osteoid, and epithelioid osteoblasts--7/30). Comparative(More)
PURPOSE To evaluate the oncological outcome of patients with grade I chondrosarcomas according to the type of surgical treatment performed, since there is still controversy regarding the need for aggressive resections to reach a successful outcome. MATERIALS AND METHODS The records of 23 patients with grade I chondrosarcomas were reviewed. The mean age(More)
OBJECTIVE The purpose of this study was to histologically analyze allografts from cadaveric semitendinous muscle after cryopreservation at -80 degrees C in comparison to a control group kept at only -4 degrees C to test the hypothesis that the histological characteristics of the tissue are maintained when the tendons are kept at lower temperatures.

PURPOSE To report the case of a woman with a diagnosis of grade II (low grade) parosteal osteosarcoma with the occurrence of myocardial metastasis 13 years after resection, and to present a review of the existing literature on the subject. METHODS Description of the case and review of the literature. CONCLUSION The review leads to the conclusion that(More)
OBJECTIVE To present a series of 50 consecutive patients with non-metastatic extremity osteosarcoma, and attempt to correlate expression of the vascular endothelial growth factor (VEGF) protein in biopsy tissue to their prognosis regarding overall survival, disease-free survival and local recurrence. METHODS Fifty cases of non-metastatic osteosarcoma of(More)
BACKGROUND Multiparameter flow cytometry is a useful tool for the diagnostic evaluation of mature B-cell neoplasms (MBN). Recently, it has been shown that CD200 may improve the distinction between chronic lymphocytic leukemia (CLL; CD200+) and mantle cell lymphoma (MCL; CD200-), but the role of CD200 expression in atypical CLL and other MBN remains to be(More)
PURPOSE To evaluate the impact of chemotherapy and surgery on the outcome of osteosarcoma (OS) of the extremities and to identify prognostic factors in Brazilian patients. PATIENTS AND METHODS A total of 225 patients with metastatic and nonmetastatic OS of the extremities were enrolled and assessed in two consecutive studies designed and implemented by(More)

The aim of this paper is to set constraints of the epochs of early-type galaxy formation through the 'archaeology' of the stellar populations in local galaxies. Using our models of absorption line indices that account for variable abundance ratios, we derive ages, total metallicities, and element ratios of 124 early-type galaxies in high and low density(More)
