[A case of ANCA negative Wegener's granulomatosis with pulmonary giant bulla showing high level of soluble ICAM-1].
This paper reports a rare case of the limited form of Wegener's granulomatosis (WG) with pulmonary giant bulla, which was pathologically identified only in the lung and showed a high level of soluble intercellular adhesion molecule-1 (ICAM-1) but not anti-neutrophil cytoplasmic antibody (ANCA). A 46 year-old male was admitted for the further examination of right anterior chest pain and dyspnea. Chest X-ray and CT examination showed giant bulla accompanied with the invasive lesions in upper lobe of right lung. Partial lobectomy was done. Granulomatous and necrotizing vasculitis characteristics of WG were confirmed by the histopathology of resected tissues. Immunological analysis on admission showed a high level of soluble ICAM-1 and ANCA negative, but that of soluble ICAM-1 was reduced after surgical operation and remained within normal range during an administration of prednisolone and cyclophosphamide. These results suggest that soluble ICAM-1 may be one of the useful parameters for a diagnosis of WG and for an estimation of its treatments, especially in the cases of ANCA negative WG.
