A patient presents with respiratory symptoms, i.e. cough, hemoptysis and glomerulonephritis. His c-ANCA levels in serum were found to be raised. The most likely diagnosis is: (A) Goodpasture’s syndrome, (B) Classic polyarteritis nodosa, (C) Kawasaki’s syndrome, (D) Wegener’s granulomatosis
Answer is D. • Both Wegener’s granulomatosis and Goodpasture’s syndrome can present similarly but presence of c-ANCA makes a diagnosis of Wegener’s granulomatosis.
