**Core Concept**
Sebaceous cysts are a type of benign skin lesion that arises from the sebaceous glands, which are responsible for producing sebum, an oily substance that helps to lubricate the skin. These cysts form when the sebaceous gland becomes blocked, leading to an accumulation of sebum and cellular debris.

**Why the Correct Answer is Right**
Sebaceous cysts typically occur on the face, neck, and trunk, where sebaceous glands are most abundant. They can also occur in areas where there is trauma or irritation to the skin, such as on the scalp or after a surgical procedure. The formation of a sebaceous cyst is often a result of a combination of genetic and environmental factors.
