Where do steatomas most commonly appear on the body?

Steatomas, also known as sebaceous cysts, are benign lumps that develop within the sebaceous glands due to the accumulation of sebum. These cysts most commonly appear on areas of the body that have a higher concentration of sebaceous glands. The face, neck, and chest are particularly prone to steatoma formation because they feature a significant amount of sebaceous glands, which are responsible for secreting oil that keeps the skin moisturized.

In contrast, the back and arms have fewer sebaceous glands relative to the facial and neck areas, making them less common sites for steatomas. The legs and feet typically contain very few sebaceous glands, leading to a scarcity of such cysts in those regions. Similarly, while the scalp and forehead do have sebaceous glands and can develop steatomas, they are mentioned less frequently compared to the face, neck, and chest as the primary locations for these cysts.

Therefore, the choice that highlights the face, neck, and chest accurately reflects the most common locations for steatomas due to the abundance of sebaceous glands in these areas.
