Mastocytosis With Associated Essential Thrombocythemia

Systemic mastocytosis associated with essential thrombocythemia.

Mastocytosis comprises a spectrum of disorders characterized by abnormal growth of mast cells (MS). Four entities are recognizable according to WHO classification. Association of systemic mastocytosis (SM) with a chronic myeloproliferative neoplasia (SM-AHNMD) is the second frequently category. Published descriptions of the clinicopathologic features of SM-AHNMD are largely limited to individua...

Essential thrombocythemia

Essential thrombocythemia (ET) is an acquired myeloproliferative disorder (MPD) characterized by a sustained elevation of platelet number with a tendency for thrombosis and hemorrhage. The prevalence in the general population is approximately 30/100,000. The median age at diagnosis is 65 to 70 years, but the disease may occur at any age. The female to male ratio is about 2:1. The clinical pictu...

INFERIOR VENA CAVA THROMBOSIS IN A PATIENT WITH ESSENTIAL THROMBOCYTHEMIA

Essential thrombocythemia is a chronic myeloproliferative disorder characterized by a sustained proliferation of megakaryocytes, which leads to increased numbers of circulating platelets. Hemorrhagic and/or thrombotic episodes are frequent, and thrombosis of both veins and arteries may develop. Vessels in unusual sites may be involved, e.g., the hepatic veins, mesenteric veins, and the dig...

Ruxolitinib for essential thrombocythemia?

Thrombospondin in essential thrombocythemia.

Essential thrombocythemia is a myeloproliferative disorder characterized by frequent bleeding and thrombotic complications. On a molecular level, two abnormalities of platelet thrombospondin have been identified: abnormal glycosylation of the intact 185,000-dalton chain has been detected and a shortened form of the thrombospondin chain is present. We have used two monoclonal antibodies and Lens...
