It occurs in women of childbearing age, although a few cases have also been observed in post-menopausal women, although it is extremely rare in the latter. Here we describe a rare case of complete hydatidiform mole in a 56-year-old female patient who presented with genital bleeding combined with nausea and vomiting and a gravid uterus 16 cm in height. The ultrasound findings and the increase in serum β-HCG to 182566.00 mIU/ml suggested a diagnosis of complete hydatidiform mole. Given the post-menopausal state and the future risk of post-molar gestational trophoblastic neoplasia, we opted for total hysterectomy without preservation of the adnexa via a transabdominal approach, followed by antimitotic treatment with methotrexate. The uterus measured 18.45 cm × 11.18 cm with intra cavitary vesicles. Microscopic examination showed chorionic villi of variable size and shape, most of which were dilated and oedematous, associated with trophoblastic cell proliferation and haemorrhage suggestive of complete benign hydatidiform mole. Follow-up showed a consistent decrease in serum β-HCG levels and no evidence of residual disease. A suspicion of gestational trophoblastic disease should be borne in mind when evaluating a patient with peri- or post-menopausal bleeding to avoid delay in diagnosis and treatment.展开更多

The diagnosis is often not easy because of the morphological similarity to a partial mole, but important to the treatment. We present a recent case in which STR polymorphism analysis clearly revealed a different genetic origin for the fetal and molar parts. STR polymorphisms on 15 variable number tandem repeat loci and a gender-determination locus, which were detected by polymerase chain reaction, indicating that the cord/placenta and molar tissue were parental and androgenous, respectively. During follow-up, the patient developed persistent gestational trophoblastic tumor (GTT) which was successfully treated with chemotherapy. In this case, STR polymorphism analysis exactly diagnosed a twin pregnancy consisting of a complete hydatidiform mole and a fetus.展开更多

The positive signals of p57 KIP2 expression were analyzed by HPIAS-1000 Image-Analysis System. p57 KIP2 was highly expressed in normal villi but showed distinct low expression in hydatidiform mole (P<0.01). Furthermore, the locus of low expression of p57 KIP2 accorded with the place where lesion of trophoblast occurred. Detection of p57 KIP2 made it possible to study the genetics of hydatidiform mole at the transcriptional level. Low expression of p57 KIP2 could be a molecular marker in hydatidiform mole and a target for therapy.展开更多

Methods: A real-time fluorescent quantitative RT-PCR (FQ RT-PCR) assay based on TaqMan fluorescence methodology and the Light-Cycler system was used to quantify the full range of hTERT mRNA copy numbers in 30 samples of hydatidiform mole and the neoplasia of hydatidiform mole. The normalized hTERT (NhTERT) was standardized by quantifying the number of GAPDH transcripts as internal control and expressed as 100x (hTERT/GAPDH) ratio. Based on the prognosis of the hydatidiform mole, the patients were divided into two groups: the experimental group and the control group, to compare the telomerase reverse transcriptase mRNA expression in peripheral blood mononuclear cells. Results: hTERT mRNA was both expressed in the peripheral blood mononuclear cells and pathological tissues in the mole experimental group and the control group. In the mole experimental group, the values were 6.31±0.32 and 6.24±0.44, respectively, and there was no significant difference between them (P〉0.05). But in the control group the values were 1.21±0.65 and 1.40±0.61, respectively, and there was no significant difference between them (P〉0.05) The values in experimental group was significantly higher than those in the control group (P〈0.01). Conclusion: Quantitative determination of hTERT mRNA by FQ RT-PCR is a rapid and sensitive method, hTERT in peripheral blood mononuclear cells may have potential use as a biomarker for the early detection of the prognosis of the hydatidiform mole.展开更多

METHODS A total of 38 hydatidiform mole samples and 30 villi samples were examined for homozygous deletions in the CDKN2A gene by PCR and for mutations by DHPLC. RESULTS i)Among 38 hydatidiform mole samples, homozygous deletions in the p16 INK4a exon 1 were identified in 5 cases(13.2%),while no homozygous deletions were found in the p16I NK4aexon 1 of 30 early-pregnancy samples.The rates of those deletions in hydatidiform compared to early-pregnancy villi samples was statistically significant(P=0.036).ii)No homozygous deletions in the p14 ARF exon 1 or p16 INK4a exon 2 were found in any of the hydatidiform moles or early-preganancy samples.iii) In all hydatidiform moles and early-pregnancy villi samples,no mutations were detected by DHPLC. CONCLUSION We suggest there may be a close correlation between homozygous deletions in the CDKN2A gene and occurrence of hydatidiform moles variation in the CDKN2A gene is mainly caused by homozygous deletions,while mutations may be not a major cause.展开更多

The purpose of this paper is to report the results of this exam, in our medical practice and try to determine if this exam should be systematic of kept only for individualized cases. Material and Methods: It was a retrospective study from January 2010 to December 2018, carried out in the Laboratory of Pathology of the Teaching Hospital of Grand Yoff in Dakar. The data were collected from the register of pathologic examinations of the laboratory. Results: We registered 543 results of histopathologic examination of products of conception from the first trimester abortion. The women mean age was 22.4 years ± 6.2 with extremes of 17 and 46 years. The routine histopathologic assessment of products of first- trimester miscarriages highlighted in our study three pathologies: hydatidiform mole (24.7%), infection (4.6%) and ectopic pregnancy (0.09%). Only 11.7% of cases of Hydatidiform mole (HM) were suspected before the histopathologic assessment. In our sample, molar pregnancy seems to be higher in anembryonic conception with a prevalence of 45%. The prevalence of Complete Hydatidiform Mole (CHM) was higher than the one of Partial Hydatidiform Mole (PHM) (14.8% vs. 9.9% of miscarriages). Indeed, both require follow up to prevent or manage at time the occurrence of choriocarcinoma. Conclusion: The results of the histologic analysis after abortion in the first trimester of pregnancy show that this exam should be practiced systematically in routine in our context because of high prevalence of hydatidiform mole.展开更多
