Is It Molluscum Contagiosum or Acne? Skin Growths

Molluscum contagiosum or acne?

Hello Doctor, about a week ago, I noticed a hemispherical flesh-colored bump about the size of a half soybean at the base of my penis.
It is not painful or itchy and appears to be firm.
When I squeeze it, it feels like there is something solid inside.
I think it resembles what is described as molluscum contagiosum on websites.
Four days ago, I punctured it with a sterilized needle, but I didn't see the white wart-like bodies being expelled as described; instead, some dark blood came out.
I have always been prone to acne, but I don't recall having any in the genital area before.
I can't tell if this bump is an acne lesion or molluscum contagiosum.
Over the past eight months, I have developed one of these hemispherical bumps at a time, sometimes on the penis, sometimes near the pubic bone, or in the area covered by pubic hair, and they usually last for two to three weeks before disappearing, some leaving scars and some not.
Does this bump look like molluscum contagiosum? Is molluscum contagiosum really a sexually transmitted infection, or is it a skin condition? Can it be transmitted to family members? Should I wash my clothes separately from my family's? I'm quite worried, and I would appreciate your answers.
Thank you! Xia.

Hello, based on your description, a precise diagnosis cannot be made.
However, common infectious warts typically increase in number and rarely resolve on their own.
I recommend that you visit a hospital for a more reassuring evaluation.
If you're feeling shy, you can take a picture with a digital camera and bring it to the hospital.

More Info

When it comes to skin growths, particularly in sensitive areas like the genital region, it is essential to differentiate between various conditions, such as molluscum contagiosum and acne. Based on your description, the growth you are experiencing could potentially be molluscum contagiosum, especially considering its characteristics and the fact that you have had similar lesions appear over the past eight months.

Molluscum contagiosum is a viral infection caused by a poxvirus, which results in small, raised, flesh-colored or pearly bumps on the skin. These bumps can be painless and may have a central dimple. They are typically spread through direct skin-to-skin contact, which can include sexual contact, but they can also be transmitted through shared objects like towels or clothing. This means that while it is often categorized as a sexually transmitted infection (STI), it can also be considered a skin condition due to its non-sexual transmission routes.

On the other hand, acne, including cystic acne, can also present as raised bumps on the skin, but they usually occur due to clogged pores and can be associated with inflammation, pain, and the presence of pus. Acne lesions typically do not have the same appearance as molluscum contagiosum and are more common in areas with a higher concentration of sebaceous (oil) glands.

Given that you have a history of easily developing acne, it is possible that you might be experiencing both conditions. However, the recurring nature of the bumps, their location, and the fact that they last for a few weeks before resolving suggest that they may be molluscum contagiosum rather than typical acne.

As for your concerns about transmission, molluscum contagiosum is contagious, and it is advisable to avoid close skin contact with others until the lesions have resolved. This includes avoiding sharing towels, clothing, or other personal items. Washing your clothes separately from those of family members may be a prudent measure to prevent potential transmission, especially if you have open lesions.

It is crucial to consult a healthcare professional for an accurate diagnosis. A dermatologist can examine the lesions and may perform a simple procedure to confirm the diagnosis, such as a biopsy or a visual examination. They can also provide guidance on treatment options, which may include topical therapies, cryotherapy, or other methods to remove the lesions.

In summary, while it is possible that the growths you are experiencing could be molluscum contagiosum, only a healthcare professional can provide a definitive diagnosis. It is essential to avoid self-treatment, such as puncturing the lesions, as this can lead to infection or scarring. Seeking medical advice will help you understand the nature of your skin condition and how to manage it effectively.
