Immune thrombocytopenic purpura (ITP) can be classified as primary or secondary according to the presence of an underlying non-malignant or malignant disorder, including lymphoproliferative disorders. The estimated prevalence of ITP in patients with Hodgkin's lymphoma is about 1%, and its clinical course has been reported in approximately 50 patients. ITP is an unusual and poorly documented complication in patients with non-Hodgkin's lymphoma. Some cases have been described in patients who have undergone high-dose chemotherapy and autologous bone marrow/peripheral blood stem cell transplantation. Rare cases appear to be coincidental. Here, we report on a rare case of a 61-year-old man who had ITP after being in a state of complete remission of non-Hodgkin's lymphoma for about 15 months. (Korean J Hematol 2009;44:113-116.)
