Cutaneous plasmacytoma in a hemodialysis patient.

Background: Extramedullary plasma cell dyscrasias are rare. Case report: We report a case of a 56-year-old male Caucasian hemodialysis patient with cutaneous plasmacytoma. The diagnosis was made a few months after surgical removal of his renal graft due to chronic rejection. Investigations for the presence of an associated myeloma were negative. He underwent local radiotherapy with complete resolution of the skin lesion. Conclusions: Nephrologists should be aware that the frequency of post-transplant lymphoproliferative disorders is increasing in the dialysis population, especially in those previously or currently treated with immunosuppressive drugs.
