Why does hydatidiform mole occur?

Why does hydatidiform mole occur?

A molar pregnancy is caused by an abnormally fertilized egg. Human cells normally contain 23 pairs of chromosomes. One chromosome in each pair comes from the father, the other from the mother.

Is hydatidiform mole curable?

Because of early diagnosis and appropriate treatment, the current mortality rate from hydatidiform mole is essentially zero. Approximately 20% of women with a complete mole develop a trophoblastic malignancy. Gestational trophoblastic malignancies (ie, gestational trophoblastic neoplasia) are almost 100% curable.

What type of cancer can rise from hydatidiform mole?

Choriocarcinoma is a rare cancer that occurs as an abnormal pregnancy. A baby may or may not develop in this type of pregnancy. The cancer may also occur after a normal pregnancy. But it most often occurs with a complete hydatidiform mole.

What tests are used for diagnosing a hydatidiform mole?

Ultrasonography, blood tests to measure human chorionic gonadotropin (which is produced early during pregnancy), and a biopsy are done. Moles are removed using dilation and curettage (D and C) with suction.

What will confirm the diagnosis of H mole?

Ultrasonography is done to be sure that the growth is a hydatidiform mole and not a fetus or amniotic sac (which contains the fetus and fluid around it). (D and C) or obtained when tissue is passed and is then examined under a microscope (biopsy) to confirm the diagnosis.

Is hydatidiform mole hereditary?

Recurrent hydatidiform mole is inherited in an autosomal recessive pattern , which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.

How common is GTD?

GTD is rare, affecting about one in every 1,000 pregnant women in the U.S. While some GTD tumors are malignant (cancerous) or have the potential to turn cancerous, the majority are benign (noncancerous). Many women treated for GTD can go on to have normal, healthy pregnancies in the future.

What is hydatidiform mole unspecified?

A hydatidiform mole contains many cysts (sacs of fluid). It is usually benign (not cancer) but it may spread to nearby tissues (invasive mole). It may also become a malignant tumor called choriocarcinoma. Hydatidiform mole is the most common type of gestational trophoblastic tumor.

What kind of pathology is the hydatidiform mole?

The hydatidiform mole The hydatidiform mole (HM) is a placental pathology of androgenetic origin. Placental villi have an abnormal hyperproliferation event and hydropic degeneration. Three situations can be envisaged at its origin: 1.

Is the hydatidiform mole a rare complication of pregnancy?

When the proliferation/invasion phenomena are not well controlled, the trophoblast cells can give rise to a rare complication of pregnancy known as a hydatidiform mole (complete or partial). These hydatidiform moles belong to the gestational trophoblastic diseases of which represent the most common pathologies.

What is the diagnosis code for mole?

Hydatidiform mole , unspecified. O01.9 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.

When do hCG levels drop after a hydatidiform mole evacuation?

Normal levels are usually reached within 8-12 weeks after evacuation of the hydatidiform mole. As long as the hCG levels are falling intervention is not needed. [ 46]
