A Case of Pulmonary Hemorrhage through Pulmonary Involvement of Henoch-Schonlein Purpura / 대한내과학회지

ABSTRACT

Henoch-Schonlein purpura (HSP) is an immunologically mediated systemic vasculitis of small blood vessels that primarily involves the skin, gastrointestinal tract, joints, and kidneys. HSP is a relatively common vasculitic syndrome in children, which usually resolves within several weeks, and requires no treatment. The pulmonary parenchymal involvement of HSP is a rare complication that predominantly occurs in adolescents and adults. Mortality following HSP pulmonary presentation is extremely high. Here, we report a case of HSP combined with pulmonary hemorrhage as a presentation of the vasculitic involvement of the lung. Recently, we experienced a case of a 49-year-old male patient with HSP who presented with palpable purpura, enteritis, and glomerulonephritis. Following the diagnosis of HSP, the patient developed sudden pulmonary hemorrhage due to the pulmonary involvement of vasculitis, and recovered following glucocorticoid therapy.
