Cytogenetic analysis of 8 cases of xenografted human osteosarcomas are reported, including six newly diagnosed and two recurrent tumors. Histologically five were osteoblastic, two were chondroblastic, and one was the microcellular type. All tumors were studied in short-term primary cultures between two and six days. Clonal and nonclonal abnormalities were(More)
Four infants had soft, skin-colored nodules in the midline plantar region of the heels since birth. The lesions were asymptomatic, bilateral, and symmetric, and measured approximately 1 cm in diameter. Their size increased in proportion to the growth of the child. In three infants the lesions persisted at 1 year of age, while in the fourth they remained at(More)
The current study disusses a new approach to the group of small round cell tumors (SRCTs) independently of their primary anatomical location. We perform this analysis supported mainly by morphological means and particularly with the help of immunohistochemistry and electron microscopy; the last of which continues to play a decisive role in their(More)
The cytogenetic analysis of a spindle-cell rhabdomyosarcoma of the parotid gland in a 6-year-old boy is reported. The tumor cells showed an abnormal karyotype with a hypotriploid modal chromosome number and clonal structural rearrangements affecting chromosomes 1, 8, 12, 21, and 22. The tumor karyotype was: 59, XY, -1, -3, -4, -5, -6, +8, +8,(More)
OBJECTIVES To observe human osteoblast behavior cultured in vitro on titanium discs (Ti) in relation to surface roughness and melatonin application. STUDY DESIGN Human osteoblasts (MG-63) were cultured on 60 Ti6Al4V discs divided into three groups: Group I: discs treated with dual acid etching; Group II dual acid etching and blasting with calcium(More)
Cytogenetic analyses of four malignant mixed mesodermal tumors (MMMT) of the uterus are reported, of which one was of the homologous type and three of the heterologous. Karyotypic analyses were obtained in two cases from original tumors and in two cases from tumors xenotransplanted into nude mice. The karyotype of the homologous MMMT was normal in three(More)
