Hi, my 6 year old son developed a small dark patch on his upper left arm several years ago. At the time I thought he just tanned unevenly but it did not go away, although it did lighten slightly during the summer months. Over the past few years it has gotten larger and has spread down the arm to just past the elbow where it seems to break up into little spots. This winter I noticed a small spot starting on the right arm as well. Now that it is pool season again and he is in the sun, the patches are darker than ever and now the left arm seems to be coming up over the shoulder. I showed his previous pediatrician when it started and she didn't seem concerned. I showed an endocrinologist, whom I did not really like, and he said, "I don't know what this rash is." Some of his other symptoms have included unexplained weight gain, night sweats, and poor sleeping. I can't imagine that nothing is causing these dark patches. Everything sounds so hormonal to me. Any ideas?Reply Follow This Thread Stop Following This Thread Flag this Discussion
