Dermatology Questions? Ask an Online Dermatologist.
Hi Dr. Ashori here, give me just a moment to reply.
If you've had it for a few years and it's unchanged then it definitely cannot be an allergic reaction.
You can upload a picture by selecting the icon for the paper clip.
The picture would help for me to tell you what it is, dermatologic lesions on the back are usually quite common and the picture would allow me to easily make the diagnosis.
Have you tried anything for this?
Does it change in any way? Has it ever gotten bigger or smaller or less raised or more raised?
This is not an allergic reaction, this is what we call sebaceous hyperplasia or small sebaceous glands which are irritated.
They aren't too hard to treat but take a little while to go away.
Let me make some suggestions and I'm sure you will see an improvement with time.
Start using something called benzoyl peroxide which is a wash that you can use to decrease the size of these things. You only need to wash the area with it, not the whole body.
Then you need to use an exfoliating wash on the area every day, salicylic acid works fine.
Then also do a topical steroid cream such as hydrocortisone 1% cream twice daily for 2 weeks.
