title: Systemic Mastocytosis Complicated by Non-Cirrhotic Portal Hypertension and Variceal Bleeding.
abstract: Systemic mastocytosis is a myeloproliferative disorder characterized by extracutaneous involvement of at least one organ. Although rare, infiltration of inflammatory mast cells within the portal vein may lead to obstruction of the sinusoids resulting in non-cirrhotic portal hypertension. We present a patient with known history of systemic mastocytosis with bone marrow involvement presenting with new-onset esophageal variceal bleeding. Although systemic mastocytosis is uncommon, the subsequent development of hepatic involvement and non-cirrhotic portal hypertension are discussed. Further highlighted is a lack of organization guidelines and the potential for gastrointestinal and hepatic screening of mastocytosis patients with known extracutaneous involvement.
