uterine leiomyomata, uterine fibroids
atypical leiomyoma of uterus ( symplastic leiomyoma )
Uterine leiomyoma occurs in about 20-30% of women over the age of 30, and is the most frequent benign tumor in gynecology.
FH-associated uterine leiomyoma
Cytogenetic analysis of uterine leiomyomata (UL) shows that about 40% of these benign tumors have simple, clonal chromosomal rearrangements.
- often associated with other aberrations, particularly loss of chromosomes 19 (19-) and/or 22 (22-)
- cellular UL
- hypercellularity and nuclear atypia
- t(10;17) disrupts the histone acetyltransferase MORF (10q22) (monocytic leukemia zinc finger protein-related factor or MYST4). (15313893)
