title: Cutaneous and Systemic Plasmacytosis Associated with Renal Amyloidosis.
abstract: Cutaneous and systemic plasmacytosis (CSP) is a rare disorder of unknown etiology characterized by cutaneous polyclonal plasma cell infiltrates associated with various extracutaneous involvement and polyclonal hypergammaglobulinemia. Here, we report on a 54-year-old male patient with chronic renal insufficiency who presented with disseminated reddish-brown macules and plaques on the face and trunk. In our evaluation, he was found to have lymphadenopathy, polyclonal hypergammaglobulinemia; benign plasma cell infiltration involving the skin, bone marrow, and retroperitoneal area; and renal amyloidosis. To the best of our knowledge, this is the first reported case of CSP associated with renal amyloidosis.
