Mesenteric and portal vein thrombosis are rare complications of splenectomy. Their presentation depends on the underlying disease. It is most frequent in lymphoproliferative disorders but extremely rare in trauma. We describe a 22-year-old man and a 49-year-old woman who underwent splenectomy for idiopathic thrombocytopenic purpura and developed mesenteric and portal vein thromboses. Both were treated successfully with anticoagulants for 3 months until the thrombi regressed, as shown by CT scan. During a year of follow-up they were asymptomatic.

Kaleidoscopic Autoimmunity

We describe an 18-year-old girl with idiopathic thrombocytopenic purpura (ITP) who developed chronic active hepatitis following splenectomy that cured the ITP. This is a phenomenon in which an organ belonging to the immune system is resected, which results in cure of one autoimmune disease but in the emergence of another, apparently unrelated, second autoimmune disease. We refer to this phenomenon as kaleidoscopic autoimmunity, explaining that some autoimmune diseases are not induced by autoantigen-driven mechanisms, but rather result from immune dysregulation.

Splenic artery aneurysm is an uncommon form of vascular disease of unknown etiology. Its clinical importance is due to its high mortality, especially in pregnancy, when maternal mortality is 70% and fetal mortality 95%. Most cases of splenic artery aneurysm are asymptomatic and are diagnosed incidentally. We present a woman with incidentally diagnosed splenic artery aneurysm in whom the splenic artery and its aneurysm were resected.

Acquired C1-inhibitor (C1-INH) deficiency has been reported in patients with immunoglobulin abnormalities and lymphoproliferative disorders, and angioedema has appeared simultaneously with the lymphoproliferative disease. We present a 50-year-old woman with acquired C1-INH deficiency and angioedema which preceded by 7 years the diagnosis of malignant mantle cell lymphoma. During the interval she was treated with Danazole and there were no attacks of angioedema. When routine follow-up bone marrow aspiration revealed infiltration of nonspecified lymphoma cells, exploratory laparotomy and splenectomy were performed. A month later Danazol was stopped, C1-INH levels returned to normal and there were no attacks of angioedema. Mantle cell lymphoma consisting of lymphocytes with cytoplasmic IgM-lambda was diagnosed in the excised spleen but chemotherapy was not initiated. 6 months later, a second lymphoproliferative disorder, multiple myeloma IgA kappa, was diagnosed.
