Systemic mastocytosis is a disease defined by an abnormal infiltration of mast cells involving several extra-cutaneous organs. Hepatic involvement is frequent, however it rarely reveals the disease. We report two cases of systemic mastocytosis revealed by hepatic symptoms: liver failure in one case and jaundice in the second case. The diagnosis is often difficult. Mast cell tissular infiltration can be identified on paraffin sections by tryptase or CD117 (c-kit) immuno-staining.
