[Systemic mastocytosis disclosed by rupture of esophageal varices].

A 77-year-old woman had variceal bleeding related to systemic mastocytosis. Physical examination revealed minimal ascites and mild hepatomegaly noted 11 years before. Liver function tests were nearly normal. Because of early recurrent bleeding, a mesocaval shunt was performed. Wedged liver biopsy showed a moderate fibrosis of portal tracts and massive mast cell infiltration within portal tracts and sinusoids. Perisinusoidal collagen deposition was demonstrated ultrastructurally. We suggest that systemic mastocytosis be added to the list of diseases related portal hypertension with perisinusoidal fibrosis. As there is currently no specific treatment, a portocaval shunt should be discussed.
