Cutaneous Light Chain Deposition Disease: A Report of 2 Cases and Review of the Literature

Abstract: Light chain deposition disease (LCDD) is a rare systemic disorder with deposition of mostly monoclonal amorphous nonamyloid light chains in multiple organs. Renal involvement with rapidly progressing renal failure presents the dominant manifestation of LCDD. Approximately 20%–30% of patients show symptomatic cardiac or liver involvement. Cutaneous manifestations are extremely rare with only a few published cases. We report 2 additional cases of cutaneous LCDD without detectable systemic disease.
