A focal lesion in the falx cerebri: Harbinger of classic stage 4 neuroblastoma in an infant cured despite residual disease after minimal therapy.

13 Dec 2009 An asymptomatic 11-week-old male received no treatment after he was classified as having a suspected atypical form of MYCN-nonamplified hyperdiploid stage 4S neuroblastoma (NB), with masses in an adrenal gland, subcutaneous tissues, and the falx ... Read more...

Cytogenetic characterization of childhood acute lymphoblastic leukemia in Nicaragua.

13 Dec 2009 BACKGROUND: Within the frame of a twinning programme with Nicaragua, The La Mascota project, we evaluated in our study the contribution of cytogenetic characterization of acute lymphoblastic leukemia (ALL) as prognostic factor compared to clinical, ... Read more...

A dynamic oral cancer field: unraveling the underlying biology and its clinical implication.

30 Oct 2009 Oral cancer is a complex disease that is characterized by histologic and genetic heterogeneity. The evolution and progression of this disease is thought to result from the accumulation of alterations in molecular pathways. Although the oral cavity ... Read more...

Technical information about 'Aneuploidy'

Definition: The chromosomal constitution of cells which deviate from the normal by the addition or subtraction of CHROMOSOMES, chromosome pairs, or chromosome fragments. In a normally diploid cell (DIPLOIDY) the loss of a chromosome pair is termed nullisomy (symbol: 2N-2), the loss of a single chromosome is MONOSOMY (symbol: 2N-1), the addition of a chromosome pair is tetrasomy (symbol: 2N+2), the addition of a single chromosome is TRISOMY (symbol: 2N+1).
