Lupus Anticoagulant-Hypoprothrombinemia Syndrome and Pseudotumor Cerebri as an Initial Presentation of Systemic Lupus Erythematosus in a 16-Year-Old Male Patient: A Case Report and Literature Review.

BACKGROUND Lupus anticoagulant-hypoprothrombinemia syndrome (LAHPS) is an exceptionally rare disease caused by prothrombin antibodies, resulting in reduced factor II levels. This disease can present with significant bleeding and is usually associated with autoimmune disorders, particularly systemic lupus erythematosus (SLE). There are currently no guidelines for the treatment of LAHPS, and corticosteroids remain the criterion standard therapy.
