**Core Concept**
A benign tumor is a type of non-cancerous growth that does not invade surrounding tissues or spread to distant sites. However, certain benign tumors can exhibit metastatic behavior, a phenomenon known as pseudometastasis or metastatic pseudopodia. This is often due to the tumor cells acquiring a malignant phenotype through genetic mutations or epigenetic changes.

**Why the Correct Answer is Right**
One classic example of a benign tumor that can show metastasis is the case of **malignant melanotic schwannoma**. This rare tumor arises from the Schwann cells of the peripheral nervous system and can exhibit aggressive behavior, including metastasis to distant organs such as the lungs, liver, and bone marrow. The metastatic behavior of this tumor is thought to be due to the acquisition of mutations in the NF1 gene, leading to the loss of neurofibromin function and the activation of the RAS-MAPK signaling pathway.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because it does not specify a particular type of benign tumor that can show metastasis. While many benign tumors can exhibit aggressive behavior, the question is asking for a specific example.
* **Option B:** This option is incorrect because it is a type of malignant tumor, not a benign tumor. Malignant tumors are characterized by their ability to invade surrounding tissues and spread to distant sites.
* **Option C:** This option is incorrect because it is a type of benign tumor that does not typically exhibit metastasis. While some types of meningiomas can be aggressive, they are generally not known to metastasize.

**Clinical Pearl / High-Yield Fact**
When diagnosing a tumor, it's essential to consider the possibility of pseudometastasis, particularly in cases where the primary tumor is benign. This phenomenon can occur in a variety of tumors, including schwannomas, meningiomas, and hemangiomas.

**Correct Answer:** C.
