A male infant, born at 32 weeks gestation by cesarean because of hydrops fetalis, presented with multiple anomalies, such as sparse and curly scalp hair, absent eyebrows, frontal bossing, an atrial septal defect, pulmonary artery stenosis, and whole myocardial thickening. He was clinically diagnosed with cardio-facio-cutaneous (CFC) syndrome, and was confirmed to have a germline V-raf murine sarcoma viral oncogene homologue B1 (BRAF) c.721 A>C mutation. At 1 month of age, he presented with a transient myelodysplastic/myeloproliferative neoplasm (MDS/MPN), which improved within a month without the administration of antineoplastic agents. This is the first report of CFC syndrome with MDS/MPN. The coexistence of MDS/MPN may be related to this BRAF c.721 A>C mutation.

Juvenile myelomonocytic leukemia (JMML) is a rare pediatric myelodysplastic/myeloproliferative neoplasm overlap disease. JMML is associated with mutations in the RAS pathway genes resulting in the myeloid progenitors being sensitive to granulocyte monocyte colony-stimulating factor (GM-CSF). Karyotype abnormalities and additional epigenetic alterations can also be found in JMML.

Genetic rearrangements involving are rare and only recently have been detected in myeloid/lymphoid neoplasms associated with eosinophilia (MLN-eos) and chronic myeloproliferative disorders. Here we report two cases with fusions in patients demonstrating mixed features of myelodysplastic/myeloproliferative neoplasms. In the first case, was fused with a new fusion partner in a patient with marrow features most consistent with atypical chronic myeloid leukemia; the second case involving - fusion was observed in a case with bone marrow features most consistent with chronic myelomonocytic leukemia.

Myeloproliferative neoplasms (MPN) are acquired clonal disorders characterized by the proliferation of bone marrow myeloid cells. Different somatic mutations have been recently associated with MPN, the most common being JAK-2 V617F. Among MPN, polycythemia vera and essential thrombocythemia are particularly associated with an increased risk to develop thrombotic complications, either arterial or venous.
