Hydatidiform mole: parental chromosome aberrations in partial and complete moles.
The relationship between parental constitutional chromosome abnormalities and the development of hydatidiform mole was evaluated in series from four institutions. Karyotype analysis was performed on blood samples from 237 patients with a pathological diagnosis of complete mole and 217 of their spouses. One patient was found to have a constitutional balanced translocation, t(11;18), while one sp...
متن کاملMolecular and Immunohistochemical Characteristics of Complete Hydatidiform Moles
Molar pregnancy is a gestational trophoblastic disease that belongs to the category of precancerous lesions. On the other end of the spectrum are gestational trophoblastic neoplasms such as invasive mole, choriocarcinoma, placental site trophoblastic tumor and epithelioid trophoblastic tumor, which are considered malignant tumors. Based on defined histopathological criteria, molar pregnancy is ...
متن کاملTetraploidy in hydatidiform moles.
STUDY QUESTION How does tetraploidy develop in hydatidiform moles (HMs), and what is the frequency of the different origins? SUMMARY ANSWER Most molar pregnancies with tetraploid cells appear to be produced by somatic endoreduplications, while a minority originate from a tetraploid zygote. The frequency of zygotic tetraploidy was estimated to be 0.7%. WHAT IS KNOWN ALREADY The parental orig...
متن کاملSex chromatin of hydatidiform moles.
The placenta is a homograft which is tolerated by the host for an unusually long time. The hydatidiform mole may be said to be even more successful in this respect for it can survive longer and penetrate further in the host even in the absence of a viable foetus. Recent observations that a large number of hydatidiform moles are chromatin positive are of much interest, but so far the reported se...
متن کاملGenetics and Epigenetics of Recurrent Hydatidiform Moles: Basic Science and Genetic Counselling
Gestational trophoblastic disease (GTD) is a group of conditions that originate from the abnormal hyperproliferation of trophoblastic cells, which derive from the trophectoderm, the outer layer of the blastocyst that would normally develop into the placenta during pregnancy. GTDs encompass hydatidiform mole (HM) (complete and partial), invasive mole, gestational choriocarcinoma, placental-site ...
