[Systemic mastocytosis with portal hypertension and hepatocellular failure].

Systemic mastocytosis is a rare disease of mast cell proliferation with cutaneous and multi-visceral involvement. Portal hypertension and ascites are rare manifestations of systemic mastocytosis. We report a case of systemic mastocytosis presenting with extensive nodular cutaneous lesions and hepatic dysfunction, manifested by portal hypertension (ascites, splenomegaly) and derangement of metabolic function (hyperammonemia, hypoalbuminemia, hypocholesterolemia), a picture resembling that of a common cirrhotic form. The correct diagnosis was established only after tissue sections were appropriately stained for mast cells. On the basis of our and other observations we suggest that systemic mastocytosis be added to the list of infiltrative diseases of the liver with potential evolution to portal hypertension and compromise of biochemical functions.
