Malignant melanoma can metastasize to virtually any organ of the body. The aggressiveness is determined by the primary site, depth of dermal invasion, presence or absence of ulceration, lymphovascular infiltration and regional lymph node involvement. We report a case of a pregnant woman with a previous history of stage 3 melanoma who presented with cardiac metastasis and placental melanoma infi...

Our in vitro perfusion study confirms the result of the Boskovic et al., that insulin lispo is not crossing the human placental membranes at low concentrations. In our study maternal steady state concentration reached 48 +/- microU in the maternal artery and 28 +/- 1 microU in the maternal vein, while in the fetal site insulin lispo was not detected. However, the concentration of insulin lispo ...

Corticotropin-releasing hormone (CRH), a hypothalamic neuropeptide involved in the regulation of ACTH secretion, has been detected by RIA in extracts of human placenta. We wished to determine whether this immunoreactive substance is a product of CRH gene expression in the placenta. We have found authentic human CRH (hCRH) mRNA in human placental tissue that is similar in size to hypothalamic CR...

Choriocarcinoma and placental site trophoblastic tumor (PSTT) are rare varieties of gestational trophoblastic disease (GTD). PSTT alone constitutes about 1-2% of all trophoblastic tumors, which presents at early reproductive age and the serum beta-hCG level is much lower than choriocarcinoma. This tumor usually invades the myometrium and its depth of penetration is a prognostic factor. The firs...
