Mastocytosis is a rare disease characterized by proliferation of mast cells in one or several organs. With conventional cytogenetics about 35% of the patients have chromosomally abnormal clones in bone marrow cells. It has been proposed to include the mast cell disease among the myeloproliferative disorders, in which trisomy for chromosome 8 and 9 can appear in the bone marrow cells. In this study bone marrow cells from eight patients with mastocytosis, two had as well an associated hematological disease, have been examined with fluorescence in situ hybridization (FISH) for enumeration of chromosome no8 and 9. In conventional cytogenetics two patients had clones with del(20) and 47,XY,+14/45, X,-Y, respectively. None of the patients with mastocytosis had clones with trisomy 8 or 9 with either cytogenetics or FISH.

Here we report a 3-year-old boy with myelomastocytic leukemia. The patient presented with fatigue and right eye proptosis. Bone marrow revealed acute myeloid leukemia with t(8;21) and trisomy 8. Induction therapy produced marked reduction in marrow myeloblasts with the emergence of 13% atypical mast cells. These cells were subsequently identified in retrospect in the diagnostic marrow consistent with myelomastocytic leukemia. His clinical course was notable for the difficulty in the eradication of the leukemic process and resembled that of adults with systemic mastocytosis with associated hematologic non-mast cell lineage disease. To the best of our knowledge, this is the youngest individual reported. The implications of mast cell lineage involvement in acute myeloid leukemia are reviewed.
