This study was purposed to characterize the first case of acute promyelocitic leukemia (AML-M(3a)) with t(15;17), trisomy 8 and tetrasomy 8, and explore its characteristics of morphology, cytogenetics, molecular biology, immunology and clinical features. Morphological changes of peripheral blood and bone marrow smears were observed under microscope. Chromosome specimen was prepared by 24 h shor...
Atypical chronic myeloid leukemia (aCML) is a rare leukemic disorder with no specific genetic lesion. Here we demonstrate clonal occurrences of tetrasomy for the long arm of chromosome 21 in a patient with aCML, and a thorough review of the literature provides evidence that this chromosomal anomaly is a so far not recognised recurrent finding in aCML. Further, the timely association of the occu...
We have analyzed 60 low-grade cervical squamous intraepithelial lesions for low- and high-risk human papillomaviruses (HPVs) and for numerical abnormalities of chromosomes 1, 3, 11, 17, and 18 and the X chromosome. Eleven of 33 lesions infected with high-risk HPVs (HPV 16, 18, 30, 31, 33, 35, 39, 45, 51, 52, 56, 58, and 66) but none of 24 lesions infected with low-risk HPVs (HPV 6, 11, 42, 43, ...
Pallister-Killian syndrome (PKS) is a multisystem sporadic genetic condition characterized by facial anomalies, variable developmental delay and intellectual impairment, hypotonia, hearing loss, seizures, pigmentary skin differences, temporal alopecia, diaphragmatic hernia, congenital heart defects, and other systemic abnormalities. PKS is typically caused by the presence of a supernumerary iso...
Chromosomal instability as manifested by increases in aneuploidy and structural chromosome aberrations is believed to play a critical role in the intermediate to late stages in the development of cervical malignancies. The current study was designed to determine the role of tetraploidy in the formation of aneuploidy and ascertain the occurrence of these alterations during the earlier stages of ...
