Association of splenoma, peliosis and lipid histiocytosis in spleen or accessory spleen removed in 2 patients with chronic idiopathic thrombocytopenic purpura after long term treatment with steroids.

In 2 patients with a long lasting cortico-dependent chronic idiopathic thrombocytopenic purpura, splenectomy in one and ablation of an accessory spleen in the other, disclosed a complex association of splenoma, peliosis and lipidosis of the spleen, with a secondary sea blue histiocytosis in one case. The relation of this curious association with thrombocytopenia and with the long treatment with corticosteroids is discussed, with a review of the literature.
