title: [Osteonecrosis in systemic lupus erythematosus. Report of 3 cases].
abstract: We present three cases of patients with systemic lupus erythematosus (SLE) and osteonecrosis or avascular necrosis (AV). Although, the pathogenesis of osteonecrosis is controversial and multifactorial, the glucocorticoids therapy is the most important factor contributing to the lesion. We report the clinical presentation of the three patients. We comment the characteristics of AV, the diagnosis and the treatment of this uncommon complication in SLE patients.
