[Pulmonar pseudotumor in granulomatosis with polyangiitis (GPA). Pulmonary cancer and/or GPA? Diagnostic implications of pulmonary nodules].
Granulomatosis with polyangiitis (GPA), formerly known as Wegener's granulomatosis, is a systemic necrotizing vasculitis, which affects small and medium sized blood vessels and is often associated with cytoplasmic anti-neutrophil cytoplasmic antibodies (ANCA). Inflammatory pseudotumor is a rare condition characterized by the appearance of a mass lesion that mimics a malignant tumor both clinically and on imaging studies, but that is thought to have an inflammatory/reactive pathogenesis. We report a patient with a GPA which was originally diagnosed as malignancy.
