Of 501 patients with chronic myeloproliferative diseases (c-MPD) 18 developed thrombosis of major abdominal vessels including 6 with hepatic vein thrombosis (Budd-Chiari syndrome). The complication was seen in 14 of 140 (10%) patients with polycythemia vera (PV), 3 of 23 (13%) patients with essential thrombocythemia (ET), 1 of 106 (1%) patients with idiopathic myelofibrosis (IMF), and none of 232 patients with chronic myelogenous leukemia (CML). Leading symptoms and signs were abdominal pain, progressive splenomegaly, widening abdominal girth, ascites, venous collaterals, and nausea and vomiting. The diagnostic modalities with highest specificity were angiography and explorative laparotomy. A causal relationship between the thrombotic event and hematocrit, thrombocyte count, or hemostatic abnormalities at the time of diagnosis could not be established. Detailed laboratory tests of platelet function and coagulation and fibrinolytic parameters of 5 surviving patients did not show any specific defect. Despite medical and surgical intervention, 39% of the patients died within 2 months after diagnosis of the thrombosis. The majority of the survivors developed further complications like liver cirrhosis with portal hypertension and esophageal varices or the short bowel syndrome after extensive bowel resection for mesenterial infarction.

A qualitative abnormality of platelet function should be considered in patients with mucocutaneous bleeding in the absence of thrombocytopenia or von Willebrand disease. Antiplatelet drugs are the most common cause of acquired platelet disorders leading to bleeding. Uremia, hepatic cirrhosis, myeloma and related disorders, polycythemia vera, essential thrombocythemia, and cardiopulmonary bypass have long been recognized as clinical situations in which platelet dysfunction may contribute to bleeding. When an acquired platelet disorder is suspected, it is useful to examine platelet function by measuring the bleeding time, examining platelet-dependent closure time in a platelet function analyzer and performing platelet aggregometry. When a specific acquired platelet disorder is diagnosed, many treatment options are available including controlling the underlying disease, giving platelet transfusions and administering a hemostatic drug.

A 52-year-old man developed essential thrombocythemia (ET) with JAK2 V617F mutation after orthotopic liver transplantation (OLT). Retrospective analysis showed that, despite a low platelet count, the JAK2 mutation was already found at presentation 14 months before OLT. The high platelet count that would have been typical of ET might be masked by the cirrhosis-related hypersplenism. Thrombocythemia became obvious after OLT. The patient subsequently developed blastic transformation 12 months afterward, a process probably accelerated by the immunosuppression required for the OLT.

Vascular events are the most common clinical complication of essential thrombocythemia, leading to sign and symptoms of this disease. There are various sign and symptoms of essential thrombocythemia, such as thrombosis in artery or vein, and enlarged spleen. Portal hypertension and hepatic cirrhosis could be caused by essential thrombocythemia via intrahepatic thrombus. Anemia in essential thrombocythemia patient treated with hydroxyurea could be the side effect of bone marrow supression and also hydroxyurea induced hemolytic anemia. Association betweeen autoimmune hemolytic anemia and primary biliary cirrhosis or hepatic cirrhosis has been discussed. This case report presented an patient diagnosed with essential thrombocythemia. He later developed hepatic cirrhosis possibly caused by intra hepatic thrombus in the setting of hypercoagulabuility in myeloproliverative disorders. He also sufferred from anemia due to hydroxyurea induced hemolytic anemia. Association between autoimmune hepatic cirrhosis and autoimmune hemolytic anemia should also be considered in this patient.

Portal vein thrombosis is caused by various diseases, including liver cirrhosis, cancer, abdominal infection, and myeloproliferative disorders. Essential thrombocythemia is one of the myeloproliferative disorders in which the bone marrow produces excessive amount of platelets and can be accompanied by various thrombotic diseases; however, essential thrombocythemia with limited cutaneous systemic sclerosis has not been reported yet. We herein report a case of extensive portal vein thrombosis due to essential thrombocythemia with limited cutaneous systemic sclerosis. A 49-year-old woman was referred to our hospital due to liver dysfunction. Extended portal vein thrombosis, splenomegaly, and thrombocytosis were founded. The examination of Janus kinase 2 V617F mutation in the bone marrow was positive. These findings resulted in the diagnosis of portal vein thrombosis due to essential thrombocythemia. Furthermore, Raynaud's phenomenon, finger's sclerosis, and positive anti-centromere antibody led to limited cutaneous systemic sclerosis. To further analyze the causal relationship between essential thrombocythemia and limited cutaneous systemic sclerosis, platelet-derived growth factor was examined. High level of serum platelet-derived growth factor, possibly caused by high platelet count due to essential thrombocythemia, was observed. As platelet-derived growth factor has been reportedly associated with the occurrence of systemic sclerosis, the present case indicates the possible causal link between essential thrombocythemia and limited cutaneous systemic sclerosis through high platelet-derived growth factor.
