Retroperitoneal fibrosis and membranous nephropathy.

We report on a patient with a past history of Pott's abscess who suffered both from a retroperitoneal fibrosis and a membranous glomerulonephritis. Five cases of retroperitoneal fibrosis and immune complex glomerulonephritis are already reported in the literature. These associations might result from a particular systemic immune response to an unknown antigen. Consequently, we consider the role of tuberculosis in our case.
