Severe pulmonary hemorrhage as the initial manifestation in systemic lupus erythematosus with active nephritis

Pulmonary hemorrhage (PH) is an uncommon clinical manifestation of patients with systemic lupus erythematosus (SLE). In this report, we describe a 14-year-old male with PH as the sole clinical manifestation of his SLE. Kidney biopsy was performed and the report revealed lupus nephritis class IVb. He demonstrated a rapid clinical response to the therapy of intravenous pulse methylprednisolone. Awareness of the possibility of PH as a sole clinical presentation of SLE may aid in the diagnosis and early aggressive management of this condition.
