Placental mesenchymal dysplasia is an underdiagnosed and a rare vascular anomaly of the placenta. It characterized by presence grape-like vesicles, which, on ultrasonography gives appearance partial mole. Histologically it can be differentiated mole absence trophoblastic proliferation. essential to make correct diagnosis as management outcome both these entities are vastly different. We present...

Gestational trophoblastic disease (GTD) is a condition of uncertain etiology, choriocarcioma, or placental-site hydatidiform moles, invasive moles, choriocarcinoma, and placental-site trophoblastic tumors. It arises from the abnormal proliferation of trophoblastic tissue and spreads beyond the uterus hematogenously. The early diagnosis of GTD is important to ensure timely and successful managem...

•An improved YASSO model is proposed by considering residual spatial autocorrelation.•Model prediction errors are minimised using GIS data at the appropriate spatial scale.•Topographical factors describe 24-49% of variation in soil carbon.

Human GCMa transcription factor regulates expression of syncytin, a placental fusogenic protein mediating trophoblastic fusion. Recently, we have demonstrated that CBP-mediated GCMa acetylation underlies the activated cAMP/PKA signaling pathway that stimulates trophoblastic fusion. Because protein acetylation is a reversible modification governed by histone acetyltransferases (HATs) and histone...

The placenta is often overlooked in the routine evaluation of a normal gestation, receiving attention only when an abnormality is detected. Although uncommon, abnormalities of the placenta are important to recognize owing to the potential for maternal and fetal morbidity and mortality. Pathologic conditions of the placenta include placental causes of hemorrhage, gestational trophoblastic diseas...

Introduction:Chorangioma is a rare primary vascular tumour of placenta with an incidence about 1% in carefully examined term placenta. Chorangiomas the past have been described as hemangiomas. Chorangioma benign, vascular, non-trophoblastic tumor plancenta that potentially threatening and can lead to hazardous feto-maternal catastrophy. Objectives: To analyse clinicopathological characteristics...

Placental chorioangioma constitutes major importance in perinatology practice, as being the most common type of placental tumors, and having the potential of devastating perinatal outcomes. In this review, we report the symptoms, diagnostic findings and recent temporary and definitive treatment choices in patients with chorioangioma.

Extrauterine epithelioid trophoblastic tumors constitute an extremely rare gestational trophoblastic disease. We report the case of an extrauterine trophoblastic tumor that was incidentally detected in the left lung. Squamous cell carcinoma was suspected after microscopically examining the specimen obtained upon preoperative needle biopsy. After surgery, the tumor was confirmed by microscopic f...
