During the summer I noticed some brown blotches on my arm. I thought it was from the sun but it hasn't gone away. There are 2 large blotches plus some smaller ones (one is raised). The others blotches are not raised, not rough, and do not itch. My family doctor looked at them and didn't know what it was. Suggested I get a skin biopsy or try a steroid cream. I've been using the cream for 9 days and there is no change. I've researched the internet but can't find any description/pictures that look like my blotches. Anyone else have blotches like these?
