Treatment of the lutein cyst in hydatidiform mole is:
**Core Concept**
The lutein cyst in hydatidiform mole is associated with high levels of human chorionic gonadotropin (hCG) production, which can lead to hyperstimulation of the ovaries. This results in the formation of multiple small ovarian cysts.
**Why the Correct Answer is Right**
The treatment of choice for lutein cysts in hydatidiform mole is methotrexate, a chemotherapeutic agent that inhibits dihydrofolate reductase, thereby disrupting DNA synthesis and cell division. This is particularly effective in reducing the size of the cysts and alleviating symptoms. The high levels of hCG in hydatidiform mole stimulate the ovaries, leading to the formation of lutein cysts, and methotrexate can effectively counteract this effect.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect as it does not address the underlying cause of lutein cysts in hydatidiform mole. Administering estrogen or progesterone would not be effective in treating lutein cysts.
* **Option B:** This option is incorrect as it does not specifically address the issue of lutein cysts in hydatidiform mole. Ovarian torsion is a complication that may require surgical intervention, but it is not a treatment for lutein cysts.
* **Option D:** This option is incorrect as it does not address the underlying hormonal imbalance that leads to lutein cysts in hydatidiform mole. Surgical intervention may be necessary in cases of ovarian torsion or rupture, but it is not a first-line treatment for lutein cysts.
**Clinical Pearl / High-Yield Fact**
It is essential to recognize that lutein cysts in hydatidiform mole are a result of the high levels of hCG production, which can lead to ovarian hyperstimulation. Methotrexate is an effective treatment for these cysts, and its use can help alleviate symptoms and prevent complications.
**Correct Answer:** A. Methotrexate
