Within the general category of mastocytosis lies an array of clinical presentations with differing prognostic implications. We report 3 cases of systemic mastocytosis distinguished by novel aspects of the disease. Case 1 documents the first successful orthotopic liver transplantation in a patient with mastocytosis; case 2 depicts a potential hereditary component of mastocytosis; and case 3 documents the progression of mastocytosis with hematologic abnormality to mast cell leukemia. Future investigations, such as the early definition of c-kit receptor mutations, may provide additional insight as to the molecular basis for this heterogeneous disease and guidance for prognostic implications and targeted therapies.
