What do round rashes on arm indicate?

default
Posted on Fri, 11 Jul 2014
Question: I have a half moon shaped skin rash that is on my two fore arms and one on my hand, and looks like another starting on my other hand.. they appear out of no where and don't go away. I had a biopsy on a small set of circular rash on my upper right arm and they said it was nothing and sometime skin does that... I've tried steroid cream etc. but now have the small circles on my upper arm and these half moon rash on my lower arms? They only itch once in a great while... not normally.

Brief Answer:
Please provide pictures and details

Detailed Answer:
Hi

I understand your concern regarding your skin problem and I hope I am able to help you in the same .
I have seen the attached picture .
I would like to tell you that the picture quality is not that great . The skin lesions are not very clear. I would suggest you to take some more close up pictures with a better resolution skin camera and upload them here on this page .
Also please tell since when do you have this problem?
Any associated itching or pain?
It would be great if you can attach picture of the biopsy report along.
Are the lesions only over the areas of hand and arms which are exposed to sun , which means the outer aspect of arms.

I am sure I will be able to help you more once you provide me the above details and the pictures .

Brief Answer:
Skin reaction, essentially harmless

Detailed Answer:
Hi again

I have seen the attached pictures .
There are two possibilities that I can think off. The first is an eczematous skin reaction and the second is granuloma annulare . Now this is also essentially a benign skin condition which leads to development of half to full circular skin lesions which in most cases do not itch. The lesions are preferably seen over dorsum of hand and arms. They are mostly harmless and may resolve with topical steroid treatment .
Now since the skin biopsy also did not show any specific changes, so it points more in favor of the above conditions .
For the time being, you can start application of Cortizone 10 cream over the affected areas twice a day . In addition , you need to use a good moisturizer to keep the lesions moisturized.
You can discuss regarding the above possibilities with your treating doctor when you see him next.
