The aim of this retrospective study was to determine the frequency, risk factors, management and prognosis of gestational choriocarcinoma at the gynaecology-obstetrics C department of the Ibn Rochd Hospital in Casablanca, Morocco over a 7-year period (2004-2010). There were 18 760 pregnancies in the study period, among which 8 cases of gestational choriocarcinoma were recorded, a frequency of 43/100 000 or 1 case of gestational choriocarcinoma in 2345 pregnancies. Maternal age ranged from 20 to 48 years. It occurred after a hydatidiform mole in 4 cases, after spontaneous miscarriage in 2 and after normal delivery in 2 cases. All the patients presented with bleeding. Metastases were found in 3 patients, including 2 with pulmonary localization. Positive diagnosis was made mainly by ultrasound and human chorionic gonadotropin level and histological confirmation was done for all cases. Polychemotherapy was used to treat 4 cases, monochemotherapy to treat 3 and one case received only radiotherapy. Of the 8 cases, 2 patients died and 6 had complete remission.

This study focuses on the preparation and characterization of platelet membrane biomimetic nanocarriers (P-PLGA NPs) and investigates their interactions with the transplacental barrier. Poly (lactic-co-glycolic acid) nanoparticles (PLGA NPs) were coated with platelet membrane (PLTM) to construct P-PLGA NPs. Additionally, fluorinated polyethylenimine (F-PEI) was grafted onto PLGA NPs to prepare F-PEI-PLGA NPs, which were compared with PLGA NPs.

Background: Primary choriocarcinoma of the pulmonary artery is an exceedingly rare malignant neoplasm, which is often misdiagnosed due to its nonspecific clinical presentation. While this condition is characterized by the presence of trophoblastic cells, typically associated with gestational trophoblastic diseases, we encountered a case occurring in an extragenital location. The rarity of such tumors makes it challenging for clinicians to consider them in differential diagnosis, especially when the initial symptoms mimic more common conditions such as pulmonary thromboembolism (PTE).

Non-gestational choriocarcinoma is an extremely rare and highly aggressive malignant tumor that arises independent of gestational events, making less than 0.6% of all ovarian germ cell tumors. Unlike the more common gestational choriocarcinoma, which is associated with pregnancy, non-gestational choriocarcinoma originates from germ cells within the ovary.

Choriocarcinoma is an uncommon, highly invasive malignancy arising from the placental trophoblastic tissue. Though staging is clinical, imaging has significant role in the diagnosis, staging, prognostic risk scoring, and management of choriocarcinomas. The purpose of this article is to review the role of multimodality imaging in the diagnosis, staging, and management of choriocarcinomas in correlation with clinicopathologic findings.
