Welcome to the forum. Wow, isn't that a fine howdy-do from your derm. First of all, I don't know how he can tell you that you do not have Lupus. Even a negative ANA does not rule out SLE. If you look at my signature, you will see a link for Lupus Criteria. If you click it you will see the 11 criteria for diagnosing Lupus (SLE). You need four of the 11 for a positive diagnoses. Your discoid lesions are one and your sun sensitivity is a second.
You would think that a derm would know the difference between rosacea and malar rash . . . I'm not sure how he is so positive . . . but I've heard that a round of certain antibiotics will rule out rosacea, as rosacea will clear with antibiotics. Make sure your take pictures of your malar rash so you will be able to show it to a rheumatologist if you end up seeing one. If you are having ANY trouble with your joints or connective tissue get yourself to a good rheumatologist. Also, you might want to dig up the old ANA test that came out positive and see if they named a pattern. There are certain patterns that are more likely to indicate lupus. . . so there would be another clue and maybe even another criteria met.
I'm so sorry your son is dealing with an AI disease. It does run in families. . . . and Lupus is auto-immune too.
You've found a very supportive group and I'm sure the others will be along to say hello soon.
Keep us posted on the results of your blood work.
