Four patients with Hodgkin's disease developed thrombocytopaenic purpura during remission phase. The interval at which it occurred following chemotherapy ranged from a period of 4 months to 4 years. Detailed investigations failed to reveal recurrence of Hodgkin's disease. All patients responded well to steroid therapy. In the median duration of one year follow-up Hodgkin's disease remained under control. Thus, the occurrence of thombocytopaenic purpura in patients treated for Hodgkin's lymphoma need not imply recurrence or active Hodgkin's disease.
