Skin issues~~ I would like to seek clarification from the doctor?

Hello Dr.
Lin, since I started working in a factory dealing with rubber and iron powder, it seems that my skin has developed some issues.
I have noticed black spots on my back that resemble acne, embedded in the skin.
When I try to squeeze them, small hard particles about the size of sesame seeds come out.
Strangely, these spots are spreading more widely.
Could you please explain what is happening? I have attached a picture at the following link: http://photo.xuite.net/cacake/6153704.
I have also undergone a full STD screening, and everything came back normal, but I am still puzzled by this condition.
Thank you for your help!

Hello: Based on your description of scattered red or brown papules in the image, you did not mention any itching.
If there is significant itching, it is generally associated with contact allergic dermatitis, which may be related to substances you have come into contact with, such as rubber dust.
If there is less itching and you can extract something resembling a comedo, it is more likely to be folliculitis or follicular keratosis.
I recommend that you visit a dermatology clinic for a definitive diagnosis and further treatment.

More Info

It sounds like you are experiencing a skin issue that has developed after working in an environment with exposure to rubber and metal dust. The appearance of black bumps or spots on your back, which resemble pimples and contain hard particles, can be concerning. Here’s a breakdown of what might be happening and how to address it.

Possible Causes
1. Folliculitis: This condition occurs when hair follicles become inflamed, often due to bacteria or irritation. The hard particles you feel could be clogged hair follicles or keratin buildup.

2. Contact Dermatitis: Given your exposure to rubber and metal, you might be experiencing an allergic reaction or irritation from these materials. This can lead to bumps, redness, and sometimes even black spots if the skin becomes hyperpigmented due to inflammation.

3. Sebaceous Cysts: These are small, non-cancerous lumps beneath the skin that can occur when sebaceous glands become blocked. They can feel firm and may appear as black or dark spots on the skin.

4. Hyperpigmentation: If there has been any irritation or inflammation, it can lead to post-inflammatory hyperpigmentation, where the skin darkens in response to injury or irritation.

5. Acne Mechanica: This is a type of acne that can occur from friction or pressure on the skin, which might be relevant if your work involves wearing tight clothing or equipment that rubs against your skin.

Recommendations
1. Avoid Picking or Squeezing: It’s important not to pick at the bumps, as this can lead to further irritation, potential infection, and scarring.

2. Consult a Dermatologist: Since the condition is worsening and spreading, it would be wise to consult a dermatologist. They can provide a proper diagnosis and treatment plan tailored to your specific situation.

3. Topical Treatments: Depending on the diagnosis, a dermatologist may recommend topical treatments such as:
- Benzoyl Peroxide or Salicylic Acid: These can help with acne-related issues by reducing bacteria and promoting exfoliation.

- Hydrocortisone Cream: If inflammation is present, a mild steroid cream can help reduce redness and swelling.

- Retinoids: These can help with skin cell turnover and may reduce the appearance of bumps and dark spots.

4. Skin Care Routine: Maintain a gentle skin care routine. Use non-comedogenic products that won’t clog your pores. Regular exfoliation can help prevent clogged follicles, but be cautious not to over-exfoliate, which can irritate the skin.

5. Protect Your Skin: If your work environment exposes you to irritants, consider wearing protective clothing or using barrier creams to minimize contact with your skin.

6. Monitor Changes: Keep an eye on the bumps. If they change in color, size, or if you experience pain or discharge, seek medical attention promptly.

Conclusion
The skin issues you are experiencing could be related to your work environment, and it’s essential to address them appropriately. Consulting a dermatologist will provide you with the best course of action tailored to your specific needs. In the meantime, avoid picking at the bumps, maintain a gentle skin care routine, and protect your skin from further irritation. Your skin health is important, and with the right care, you can manage these issues effectively.
