Generalized cutis laxa associated with heavy chain deposition disease

Stephen Tan, Kucy Pon, Joanne Bargman, Danny Ghazarian
Journal of Cutaneous Medicine and Surgery 2003, 7 (5): 390-4

BACKGROUND: Cutis laxa is a heterogeneous group of inherited and acquired disorders characterized clinically by loose skin and histologically by altered elastic tissue. Heavy chain deposition disease is a very rare monoclonal immunoglobulin disorder, distinct from multiple myeloma, in which there is production and deposition of defective immunoglobulin heavy chains without light chain deposition.

OBJECTIVE: We describe a case of acquired cutis laxa associated with heavy chain deposition disease.

RESULTS: A 50-year-old male presented with acute renal failure, IgG4 heavy chain deposition in the kidneys, and no evidence of multiple myeloma. Four years later, he developed generalized acquired cutis laxa, emphysema, and a peripheral polyneuropathy. On pathology, there was destruction of elastic fibers within the dermis.

CONCLUSION: This case describes a previously unreported association between acquired cutis laxa and heavy chain deposition disease.
