mucinous carcinomas with associated ovarian teratoma

Friday 5 July 2013

The tissue derivation of mucinous ovarian carcinoma remains a mystery; however, rare tumors are associated with mature teratoma. Studies of chromosomal heteromorphisms and DNA polymorphisms proved that ovarian teratomas arise during female gametogenesis.

Microsatellite polymorphism analysis demonstrates that mucinous ovarian carcinomas usually clonally match associated teratomas when present and often show evidence of complete isodisomy, indicating that at least some mucinous carcinomas arise from female gametes and thus are of germ cell origin.

The zygosity patterns in mucinous carcinomas without teratoma suggest that these tumors may arise through a different mechanism.
