title: [Systemic lupus erythematosus in a 6 year old female child].
abstract: Systemic lupus erythematosus (SLE) is an uncommon disease, particularly in the first decade of life. Finding it before the first year of life is very rare and it entails a difficult diagnosis to document because the clinical manifestations can be very variable and can simulate a great variety of diseases. In the pediatric age, incidence of SLE is 0.36-0.9/100 000 children, with greater prevalence in females 3:1 under 12 years of age and 10:1 in patients over 12 years. There is a very low incidence of SLE before 4 years of age. We present the clinical case of a 9 month-old female in whom four criteria of SLE were clearly documented at 6 months of age. In a review of literature, this is the youngest patient reported with SLE. Physicians must be very alert of the higher risk of systemic complications in children that are diagnosed with SLE at an early age.
