[Allergic vasculitis in benign prostatic hyperplasia combined with a latent prostatic carcinoma].
Histological examination of the removed prostate from a 66-year-old patient discovered glandular hyperplasia, atypical hyperplasia and small focus of poorly differentiated (latent) adenocarcinoma. There were nodular lymphocytic infiltrates in the adenoma, in the peripheral parts of the node there was destructive thrombovasculitis and productive granulomatous vasculitis in the presence of diffuse lymphohistiocytic infiltration. Vascular changes resembled those in Winiwarter [correction of Winivater]-Berger disease. Vasculitis is thought an allergic reaction.
