A case of pityriasis rubra pilaris associated with membranous nephropathy

Abstract

Pityriasis rubra pilaris (PRP) is a rare idiopathic dermatosis which may be associated with autoimmune diseases, HIV infection, and internal malignancies. Its association with renal diseases is, however, much less recognized. We report a case of PRP with associated membranous nephropathy (MN), which resolved spontaneously with resolution of the dermatosis. This is only the second reported association between PRP and MN of which we are aware. Further reports of such an association will strengthen the evidence for the two conditions being linked and may thereby shed light on the pathogenesis of both PRP and MN. © 2011 The Authors.
