True about border line ovarian tumors is all except
**Borderline Ovarian Tumors**
**Core Concept**
Borderline ovarian tumors (BOTs) are a type of ovarian neoplasm that exhibit both benign and malignant characteristics. They are also known as tumors of low malignant potential (LMP). BOTs are typically composed of neoplastic cells that have the potential to invade but do not exhibit the typical features of high-grade ovarian cancer.
**Why the Correct Answer is Right**
Borderline ovarian tumors are characterized by the presence of psammoma bodies, which are small, calcified concretions found within the tumor. They are also often associated with a mucinous or serous histological subtype. The cells in BOTs often exhibit a mild to moderate level of atypia and may exhibit a single layer of cells, but they do not exhibit the typical features of high-grade ovarian cancer, such as extensive stromal invasion or high-grade cytological atypia.
**Why Each Wrong Option is Incorrect**
**Option A:**
*Option A was not provided, so we will skip it*
**Option B:**
There is no evidence to suggest that borderline ovarian tumors are associated with a higher risk of ovarian cancer in the general population, although they may be associated with a higher risk in families with a history of ovarian cancer.
**Option C:**
Borderline ovarian tumors are not typically associated with a high risk of metastasis or recurrence, especially if they are properly treated with surgery.
**Option D:**
While it is true that borderline ovarian tumors are often associated with a mucinous or serous histological subtype, this statement is not the best answer to the question, as it is not an exception to the characteristics of BOTs.
**Clinical Pearl / High-Yield Fact**
One key point to remember is that borderline ovarian tumors are often associated with a better prognosis than high-grade ovarian cancer, especially if they are properly treated with surgery. This is because they do not exhibit the typical features of high-grade ovarian cancer, such as extensive stromal invasion or high-grade cytological atypia.
**Correct Answer:** A.
