Mb. Kennymoynihan et al., LOSS OF AN X-CHROMOSOME IN AGGRESSIVE ANGIOMYXOMA OF FEMALE SOFT PARTS - A CASE-REPORT, Cancer genetics and cytogenetics, 89(1), 1996, pp. 61-64
Cytogenetic analysis of an aggressive angiomyxoma of the vulvar region
of a 16-year-old female revealed loss of one X chromosome (45,X, -X)
in eight of 20 metaphase cells analyzed. Fluorescence in situ hybridiz
ation (FISH) performed on disaggregated cells from paraffin embedded l
esional tissue confirmed loss of an X chromosome in 31% of cells. Cyto
genetic analysis performed on peripheral blood showed a normal chromos
omal complement (46,XX). Thus, loss of one X chromosome appears to be
confined to the neoplasm. This anomaly has not been previously describ
ed in aggressive angiomyxoma.
