Persistent Red Bumps on Abdomen: Causes and Concerns Explained

Red bumps on the abdomen that have persisted for two years?

Hello, Dr.
Wu.
I sometimes have red bumps on my abdomen that resemble folliculitis, accompanied by small pustules.
They leave marks that take months to heal.
However, one or two of them may have become persistent because I squeezed the pustules.
Occasionally, they can be itchy, and when scratched, they become slightly raised and hard, but then they subside after a day.
The red papules are about 0.5 cm in size, and two of them have not resolved for two years.
Generally, they are not itchy or painful, but occasionally they can be slightly itchy.
When scratched, a hard bump appears and then disappears again, repeating this cycle.
I am unsure what this could be.
If it itches, will it gradually disappear if I refrain from scratching? Could this be the basal cell carcinoma reported recently? However, since it is on my abdomen, which hasn't been exposed to much sunlight, that seems unlikely.
I am somewhat concerned, but I also feel that these are just minor red papules, and I wonder if it would be an overreaction to see a doctor.
So I am asking you online first.
Thank you!

Without actually seeing the lesion, it cannot be confirmed.
It is recommended to have a dermatologist examine it to determine the condition.

More Info

Persistent red bumps on the abdomen can be concerning, especially when they resemble folliculitis or other dermatological conditions. Based on your description, it seems you are experiencing recurrent red bumps that may contain pus, and some have persisted for a long time. Let’s break down the potential causes and concerns regarding these symptoms.

Possible Causes
1. Folliculitis: This is an inflammation of the hair follicles, often caused by bacterial infections, irritation, or blockage. It can present as small red bumps or pustules, which may itch or be tender. If you have been squeezing these bumps, it could lead to further irritation or infection.

2. Sebaceous Cysts: These are non-cancerous lumps beneath the skin that can occur when sebaceous glands become blocked. They can sometimes become inflamed or infected, leading to redness and discomfort.

3. Dermatitis: Contact dermatitis or allergic reactions can cause red, itchy bumps on the skin. If you have come into contact with an irritant or allergen, this could be a possible cause.

4. Acne: While typically associated with the face, acne can occur on other parts of the body, including the abdomen. This can lead to the formation of red bumps or cysts.

5. Skin Infections: Bacterial or fungal infections can cause persistent red bumps. If these bumps are itchy and inflamed, it may indicate an infection that requires treatment.

6. Basal Cell Carcinoma: While it’s less likely given your description and the location of the bumps, persistent lesions that do not heal should be evaluated by a healthcare professional to rule out skin cancer, especially if there are changes in size, color, or texture.

Concerns and Recommendations
Given that you have had some of these bumps for two years without significant change, it is advisable to seek medical attention. While it may seem minor, persistent skin lesions should not be ignored, especially if they change or cause discomfort. Here are some steps you can take:
- Avoid Squeezing: As tempting as it may be, avoid squeezing or scratching the bumps. This can lead to further irritation, potential infection, and scarring.

- Monitor Symptoms: Keep track of any changes in the bumps, such as increased size, color changes, or if they become painful. Note any new symptoms like fever or systemic signs of infection.

- Consult a Dermatologist: It would be wise to consult a dermatologist who can perform a thorough examination. They may recommend a biopsy or other diagnostic tests to determine the exact nature of the bumps.

- Skin Care Routine: Maintain a gentle skin care routine. Avoid harsh soaps or products that may irritate your skin. Consider using non-comedogenic moisturizers if you have dry skin.

- Consider Allergies: If you suspect that an allergy may be causing your symptoms, try to identify and avoid potential allergens in your environment or products.

Conclusion
While it is understandable to feel hesitant about seeking medical attention for what seems like a minor issue, persistent skin changes warrant a professional evaluation. Early diagnosis and treatment can prevent potential complications and provide peace of mind. If you are concerned about the possibility of skin cancer or other serious conditions, it is always better to err on the side of caution and consult a healthcare provider.
