Complex karyotypic anomalies, including an i(5p) marker chromosome, in malignant mixed mesodermal tumor of the ovary.
Cytogenetic analysis of short-term cultures initiated from an ovarian malignant mixed mesodermal tumor yielded the following karyotype: 59-61, XX,t(1;?)(p36;?), +t(1;9) (q43;q21), +t(2;?)(p25;?), +i(5p), +i(5p), +7, +t(7;?)(p13;?), +8,der(11) (pter----cen----q23::q13----q23::q13----q23::?), +12, + der(13)t(13;15)(q21;q15), -15,der(16) (16qter----cen----16p13::hsr::8q21----8qter), +19, + der(20)t(X;20)(q13;p13), -22, +4 - 6mar. Because the only other cytogenetically characterized ovarian neoplasm of this rare histopathologic subtype also had a small metacentric marker interpreted as an isochromosome for the short arm of a B-group chromosome, we suggest that i(5p) constitutes a nonrandom anomaly in mixed mesodermal tumors.
