We report a 45-year-old woman with a systemic lupus erythematosus complicated with a tuberculous mastitis. The patient developed bilateral breast swelling. Neoplasia was ruled out by radiological investigations. Biopsy and histological examination were consistent with the diagnosis of breast tuberculosis. It’s a rare infectious complication in patients with systemic lupus erythematosus. A breast neoplasia or a lupus mastitis should be ruled out by appropriate investigations and deep biopsies. The first line treatment is based on anti tubercular drugs.
