Molar pregnancy
Molar Pregnancy
A Molar Pregnancy (pronunciation: /ˈmoʊlər/ /ˈprɛɡnənsi/), also known as Hydatidiform Mole (pronunciation: /haɪˌdætɪˈdɔːrəm/ /moʊl/), is a rare complication of pregnancy characterized by the abnormal growth of trophoblasts, the cells that normally develop into the placenta.
Etymology
The term "molar" originates from the Latin word "mola" meaning "millstone", due to the resemblance of the hydatidiform mole to a millstone in the uterus. The term "hydatidiform" is derived from the Greek words "hydatis" meaning "water" and "forma" meaning "shape", referring to the water-filled, grape-like shape of the molar tissue.
Types
There are two types of molar pregnancy: Complete Molar Pregnancy and Partial Molar Pregnancy. In a complete molar pregnancy, the ovum's genetic material is lost and replaced with the sperm's genetic material, resulting in a non-viable pregnancy. In a partial molar pregnancy, two sperm fertilize an ovum, leading to an abnormal embryo and an abnormal placenta.
Symptoms
Symptoms of a molar pregnancy may include vaginal bleeding, severe nausea and vomiting, and rapid enlargement of the uterus. In some cases, a molar pregnancy can lead to gestational trophoblastic disease or choriocarcinoma, a rare form of cancer.
Diagnosis and Treatment
Diagnosis of a molar pregnancy typically involves ultrasound imaging and hCG (human chorionic gonadotropin) level testing. Treatment usually involves surgical removal of the molar tissue, followed by close monitoring of hCG levels to ensure complete removal and to detect any potential complications.
