Tetraploidy 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 کاملMolar Pregnancy (Hydatidiform Moles) and Choriocarcinoma — Symptoms and Treatments
During pregnancy, it is possible for the tissue surrounding the embryo to degenerate. Such degeneration typically manifests itself in hydatidiform moles and choriocarcinoma. These tumors are difficult to diagnose and are associated with an increased level of beta hCG. Treatment involves the complete removal of the tumorous growth. The characteristics of the tumors are described in more detail b...
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 کاملSTR DNA genotyping of hydatidiform moles in South China.
OBJECTIVE To evacuate whether short-tandem-repeat (STR) DNA genotyping is effective for diagnostic measure to precisely classify hydatidiform moles. METHODS 150 cases were selected based on histologic features that were previously diagnosed or suspected molar pregnancy. All sections were stained with hematoxylin as a quality control method, and guided the microscopic dissection. DNA was extra...
