What are these marks on my skin? - picture of ringworm healing

The other night I felt a slight burning, tingling sensation in my shoulder. I went looking for a look in the mirror and saw my fair skin usually have dark markings. The first thing I noticed was a dry place, as an almost perfect circle. It is more emphasized. And I had some dark spots beneath him.

Here are the pictures (are ignoring the soil is very thin and does not heal after a new):

My parents say it is not ringworm, but I'm not sure. What is it? I would like to answer properly this can disappear.
