Abstract
Autoimmune paraneoplastic processes are investigated in detail concerning the Lambert-Eaton-Myasthenic-Syndrome for bronchial carcinomas. For the cutaneous leukocytoclastic vasculitis as a non-ANCA-associated vasculitis the paraneoplastic genesis is described. Litttle is known about ANCA-associated vasculitis as a paraneoplastic autoimmune phenomenon. We present the case of a 62 year old woman referred to our hospital presenting air-space shadows mainly in both upper lobes, skin rash with petechial bleeding and a highly positive pANCA-titer. A bronchioloalveolar carcinoma was diagnosed by surgical biopsy. The patient developed renal failure postsurgically and died a few weeks after the diagnosis was established. This is the 5 (th) case in literature of the temporal concurrence of a bronchial carcinoma and an ANCA-associated vasculitis. So far only 24 cases of a solid tumor occuring simultaneously with an ANCA-positive vasculitis are reported in literature.
