[Specific renal lesions revealing the presence of sarcoidosis (author's transl)]

Abstract

Three cases of granulomatous nephropathy are reported. In two patients this was definitely related to a true renal sarcoidosis, while the third case raised the problem of the significance of an "isolated sarcoidosis nodule". The authors discuss the frequency, clinical symptoms, and pathological appearances of these renal lesions which reveal the presence of sarcoidosis, as well as the relationship between renal insufficiency and the parenchymatous lesions observed, and therapy.
