What is placental teratoma?

Placental teratoma is a rare nontrophoblastic benign tumour, which is thought to arise from germ cells. These tumours contain elements derived from multiple germ cell layers. We report a case of teratoma, where on ultrasound; there were two echogenic masses of 4 cm × 5 cm and 3 cm × 4 cm, arising from the placenta.

What causes a chorioangioma?

The cause of chorioangioma is unknown. The abnormal masses form in the chorionic tissue, the tissue on the fetal side of the placenta. Chorioangiomas occur in an estimated 1% of pregnancies. The tumors are seen more often in pregnancies where the fetus is female and in those involving multiples (twins, triplets, etc.).

What is chorioangioma of the placenta?

Placental chorioangioma is the most common benign non-trophoblastic tumor of the placenta. It is derived from primitive chorionic mesenchyme and is typically vascular. Placenta chorioangiomas occur in approximately 1% of pregnancies. Most placental chorioangiomas are small and are not clinically important.

What causes Succenturiate placenta?

Advanced maternal age and in vitro fertilization are risk factors for the succenturiate placenta. Other factors leading to succenturiate placentas include implantation over leiomyomas, in areas of previous surgery, in the cornu, or over the cervical os.

What is bipartite placenta?

A bilobed placenta also referred to as bipartite placenta, is a variation in placental morphology and refers to a placenta separated into two near equal-sized lobes. If more than two lobes are present, it is termed a trilobed, four-lobed and so on.

How common is chorioangioma in placenta?

Placental chorioangiomas are benign vascular tumours and are the most common placental tumours, with a prevalence of 1%. Large placental chorioangiomas are rare and may lead to pregnancy complications and poor perinatal outcomes.

How do you treat chorioangioma?

The combined use of bipolar cautery with a diode laser proved to be an effective treatment option for symptomatic chorioangioma. With bipolar cautery, surgeons were able to reduce the blood flow to the chorioangioma by coagulating the main feeding vessel, which was too large to be safely coagulated by the laser diode.

Is Succenturiate placenta high risk?

Conclusion: The results suggest that the incidence of succenturiate placenta increases along with an increase in pelvic infection, infertility, and preeclampsia. The condition of succenturiate placenta increases the risks for prematurity, impaired fetal growth, and cesarean delivery.

How common is Succenturiate placenta?

This condition occurs in 5% of placentas. Advanced maternal age and in vitro fertilization are risk factors for the succenturiate placenta.

What causes bipartite placenta?

Usually in singleton pregnancy, there is one placenta and one cord. But bilobed placenta is thought to result from localized atrophy as a result of poor decidualization and vascularization in a part of the uterus2. Usually it is associated with velamentous insertion of cord.

What does a growth on the placenta mean?
