## **Core Concept**
Fordyce spots, also known as Fordyce granules, are small, yellowish or white bumps that can appear on the lips, inside of the cheeks, and sometimes on the genitals. They are a benign condition and represent ectopic sebaceous glands.

## **Why the Correct Answer is Right**
The correct answer relates to the nature and appearance of Fordyce spots. They are ectopic sebaceous glands that appear as small, yellowish or white bumps. These spots are more noticeable when the skin is stretched. They are a normal anatomical variant and not a pathological condition.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is incorrect because Fordyce spots are not indicative of a sexually transmitted infection (STI), nor are they typically painful or itchy.
- **Option B:** This option is incorrect as Fordyce spots do not require treatment as they are benign and do not cause any symptoms.
- **Option C:** This option might seem plausible but is incorrect because while Fordyce spots can appear on the genitals, they are not directly related to genital herpes or other infectious diseases.
- **Option D (Correct Answer):** Since this is the correct answer, we focus on why the others are wrong.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that Fordyce spots are a benign condition and should not be confused with pathological conditions such as STIs or skin diseases. They are relatively common and can be found in many people.

## **Correct Answer:** D. Ectopic sebaceous glands.
