Welcome to the forum. Sorry to hear of your skin involvement. SLE can present skin involvement, but it would also be showing up elsewhere in the body, attacking other organs. The "S" in SLE means systemic, or "all of body".
What you might have instead of SLE is DLE. Discoid Lupus Erythmatosis. Where the disease only attacks the skin.
More biopsies and blood tests will be needed to get a firm diagnosis. Are you having any other symptoms that would lead to SLE?
