Recurrency of idiopathic thrombocytopenic purpura due to hypertrophied accessory spleens

Idiopathic thrombocytopenic purpura is an autoimmune disease in which macrophages of reticuloendothelial system, mainly in the spleen, remove platelets covered by autoantibodies from circulation. By removing the spleen 60-80% of patients are cured. Partial remission is achieved in 10-20% cases. Very few patients do not react on splenectomy. Recurrency of idiopathic thrombocytopenic purpura in a splenectomized patient after already achieved complete remission, may be caused by hypertrophy of one or more of the retained accessory spleens. We present 3 patients, 41, 23 and 44 year old, in whom splenectomy for ITP had been performed 10, 3 and 11 years earlier. After full remission which lasted 10, 2.5 and 10.5 years a full recurrency of ITP took place with signs of severe thrombocytopenia and haemorrhagic syndrome. Using ultrasonography, computed tomography and scintigraphy accessory spleen/s, were discovered. By their removal, a full remission was achieved in all 3 patients, but full favorable effect appeared approximately three months after surgery during which period additional steroid therapy was necessary.
