title: False positive pleural biopsy and high CA125 levels in serum and pleural effusion in systemic lupus erythematosus.
abstract: A 23-year-old female with systemic lupus erythematosus is reported. The clinical features included fever, shortness of breath, lymphadenopathies, hepatosplenomegaly, pleural and pericardial fluids, ANA and Anti-DNA positivity.
