Here we report a successful protocol in treatment of a patient with primary plasma cell leukemia (PPCL) using haploidentical stem cell transplantation (hi-HSCT). During first complete remission after routine chemotherapy, the patient received autologous blood stem cell transplantation, but he had relapse later. He gained a second CR after chemotherapy and underwent hi-HSCT from his daughter, who had HLA mismatched at three loci. Recovery of hemopoiesis was found at day 14 and complete donor chimerism was confirmed by PCR-STR on day 34, 95 and 238. The patients have survived disease-free for 56 months since hi-HSCT, without serious graft-versus-host-disease.
