Introduction: Secondary antiphospholipid syndrome (SAPS) ia APS that occurs in the context of another medical condition. Althgough antiphospholipid antibodies (aPL) can occur in patients with viral, bacterial or protozoal infections, they are rarely associated with thrombosis.

Aim: To present an uncommon case of pneumonia and pleural effusion complicated with pulmonary thromboembolism in a patient with systemic lupus erythematosus (SLE), due to non-diagnosed secondary antiphospholipid syndrome.

Case report: 


secondary antiphospholipid syndrome, antibodies, systemic lupus erythematosus, autoimmunity, thrombosis
