An unusual pediatric case with neurofibromatosis and systemic lupus erythematosus

Neurofibromatosis type 1 (NF1) is a relatively common autosomal dominant disorder affecting mainly ectodermal and mesodermal tissues. It is well known that patients with NF1 have an increased risk of developing benign and malignant tumors, but its association with autoimmune diseases has been rarely reported. Systemic lupus erythematosus is an autoimmune chronic inflammatory disease that has the potential to affect various organ systems. There are four cases with NF1 and SLE reported in the literature up to date. Here, we report a 9-year-old girl presenting with NF1 and SLE, and to our knowledge, this is the first childhood case in the literature.
