title: Ptosis in Waldenström's macroglobulinemia.
abstract: OBJECTIVE
  To report a case of chronic, progressive unilateral blepharoptosis in a 73-year-old woman with Waldenström's macroglobulinemia.
  
  
  METHODS
  Case report. A biopsy was performed on a thickened and indurated tarsal plate that we believed had resulted in mechanical blepharoptosis.
  
  
  RESULTS
  Histologic and immunohistochemistry studies of the biopsy specimen demonstrated a lymphoplasmacytoid cell infiltrate with monoclonal antibodies consistent with Waldenström's macroglobulinemia.
  
  
  CONCLUSIONS
  Involvement of the tarsal conjunctiva and tarsus in Waldenstrom's macroglobulinemia is a newly recognized cause of eyelid thickening and ptosis.
