Hello, can you describe the appearance of the area?
What size is the spots?
Are you able to take a digital photo so we can look at the area?
Have you used any creams or treatments?
There are few things that need to be ruled out. Ringworm is a common cause of a flat red area, and we would expect the area in the center to become more pink as the ring spreads. The other possibility is eczema and this is usually an atopic problem that responds to mild steroids.
The other circular rash that we want to rule out is Lyme Disease following exposure to a tick. Have a look at this site: here
If you have the advanced toolbar, then use the tree icon to load the image although this may depend on the size. If you have problems, email the images to firstname.lastname@example.org who will upload them for you.
I will be in theatre today, but will look at them once I'm free if that is satisfactory for you.
Is there a reason why you are especially worried about cancer?
Thanks for the photographs they are very useful. I would suggest ten days of clotrimazole or miconazole 1% cream twice daily to rule out fungal infections. Although I would have expected them to continue to grow more in size, the appearance is that of fungal.
Once we know anti-fungals do not work then you can use a hydrocortisone 1% cream twice daily for 7 days. That should make a good improvement in their appearance if this is eczema and if there is no response to that you should see a dermatologist for skin scraping.
They do not look sinister and within a few weeks should be looking much better.
