Yellow Bumps Under the Foreskin: Causes and Concerns

Preputial yellow spots

I recently pulled back my foreskin and noticed a group of yellowish, approximately 1mm raised spots that resemble pimples.
They are not painful or itchy, and I can't squeeze them out.
What could this be? I am 12 years old.

The yellow substance you notice during your first cleaning of the glans and foreskin is typically smegma.
If there are no changes such as redness, swelling, heat, pain, or increased discharge after cleaning, you can usually continue to observe and maintain cleanliness.
However, if any changes occur, it is advisable to consult a healthcare professional for evaluation and examination.
It is important to note that a simple description cannot determine the condition; a thorough medical history and physical examination are necessary.
Physicians often require a detailed history, visual inspection, palpation, and additional tests to establish a diagnosis and treatment plan.
If you suspect any medical issues, it is recommended to seek evaluation and treatment from a nearby urologist.

More Info

When it comes to the appearance of yellow bumps under the foreskin, especially in a 12-year-old, there are several potential explanations. It's important to understand that the genital area can exhibit various normal and abnormal conditions, and the presence of these yellow bumps may not necessarily indicate a serious issue.
One common cause of yellowish bumps under the foreskin is the presence of pearls of Fordyce. These are small, painless, pale yellow or white bumps that are actually sebaceous glands that are not associated with hair follicles. They are completely normal and are often more noticeable in adolescents due to hormonal changes. Fordyce spots are harmless and do not require treatment unless they cause psychological distress.

Another possibility is pearly penile papules, which are small, dome-shaped bumps that typically appear around the corona of the glans (the head of the penis). Like Fordyce spots, these are also normal anatomical variations and are not a sign of any disease or infection.

However, if the bumps are accompanied by other symptoms such as itching, pain, or discharge, it could indicate a condition that requires medical attention, such as a bacterial or fungal infection. Conditions like balanitis, which is inflammation of the glans, can occur due to poor hygiene, irritation, or infections. In such cases, it is essential to maintain proper hygiene and consult a healthcare provider for appropriate treatment.

In rare cases, yellow bumps could also be related to sexually transmitted infections (STIs), especially if there has been any sexual activity. However, at the age of 12, this is less likely unless there has been exposure to such activities.
Given your age and the nature of the bumps being painless and not causing any discomfort, it is likely that these are normal anatomical features. However, it is always a good idea to consult a healthcare professional, such as a pediatrician or a urologist, for a thorough examination and to rule out any potential issues. They can provide reassurance and guidance on proper hygiene practices and any necessary follow-up.

In summary, while yellow bumps under the foreskin can be concerning, they are often benign and related to normal anatomical variations. Maintaining good hygiene and seeking medical advice when in doubt is the best course of action. If you notice any changes in the bumps, such as increased size, pain, or discharge, it is essential to seek medical attention promptly.

It's really too detailed, but the entire process doesn't seem like a rash infection, and it doesn't look like a "sexually transmitted disease." I suggest you visit a hospital to see a urologist for an examination.
