[Goodpasture's syndrome with negative renal immunofluorescence].
The diagnosis of Goodpasture's syndrome is established by the clinical setting of diffuse alveolar hemorrhage and glomerulonephritis, and the demonstration of circulating or tissue-bound antibasement membrane antibodies. However, cases of Goodpasture's syndrome limited either to the lungs or kidneys have been reported. The absence of immune deposits from renal biopsy specimens of a patient with Goodpasture's syndrome, even with normal renal function, is exceptional. We report here a case of Goodpasture's syndrome characterized by direct immunofluorescence staining of the transbronchial biopsy specimen, and with direct negative immunofluorescence on renal biopsy specimen.
