Systemic lupus erythematosus presenting as acute lupus pneumonitis in a young female.

Acute lupus pneumonitis is a rare initial presentation of systemic lupus erythematosus (SLE). We report a 19-year-old female presenting with fever and recurrent hemoptysis with radiological evidence of parenchymal lung involvement with mild pleural effusion. Subsequent development of malar and discoid rash with anti-nuclear antibodies (ANA) and anti-dsDNA positivity clinched the diagnosis. Her clinical signs and symptoms resolved with a course of intravenous pulse methyl-prednisolone along with radiological resolution.
