Abstract

Two months after surgical resection of a bronchogenic carcinoma, a 69-year-old patient presented with Schönlein-Henoch purpura with kidney involvement followed by pulmonary hemorrhage. The presence of an IgA linear pattern on the kidney biopsy specimen and circulating anti-glomerular basement membrane (GBM) IgA antibodies led to the diagnosis of Goodpasture syndrome, which implies the possibility that the well-known pulmonary involvement during the course of Schönlein-Henoch purpura could be caused by Goodpasture syndrome in certain cases. In cases of glomerulonephropathy with lung involvement, clinicians should not limit their investigations to anti-GBM IgG. © 2002 by the National Kidney Foundation, Inc.

Case report

A 69-year-old patient had undergone surgery 2 months before admission to our department. The patient had been a smoker up to 2 months before admission, was hypertensive on medical treatment, and had a past medical history of bronchogenic squamous cell carcinoma in the right upper lobe (4.5 cm in diameter, infiltrating parietal pleura, without hilar or mediastinal lymph node involvement). A superior and medial bilobectomy had been performed with mediastinal lymphadenectomy and section of the

Discussion

The diagnosis of Goodpasture syndrome requires the demonstration of anti-GBM circulating antibodies and a characteristic linear pattern on direct immunofluorescence, which is usually IgG, but occasionally non-IgG antibodies can be present or both.4 Lung neoplasms have been noted among the precipitating factors that can trigger Schönlein-Henoch purpura.5 In the present case, although we did not have pathology samples of the pulmonary lesions, the presence of glomerulonephritis with linear IgA
