Wegener's granulomatosis mimicking paraneoplastic syndrome.
Wegener's granulomatosis is a distinct clinico-pathological entity characterised by a triad of upper and lower respiratory disease and renal involvement, although atypical presentations can be seen. These patients characteristically have small vessel vasculitis and or granulomatous vasculitis and are usually anti-neutrophilic cytoplasmic antibody (ANCA) positive. We present a case of Wegener's granulomatosis that clinically mimicked a lung neoplasm with a paraneoplastic syndrome. Biopsy and histopathological evaluation of a readily accessible subcutaneous nodule showed small vessel vasculitis. Correlation with clinical data and ANCA positivity led to a definite diagnosis.
