Abstract

The myeloproliferative neoplasms are classified in four major diseases: Chronic Myeloid Leukemia, Polycythemia Vera, Primary Myelofibrosis and Essential Thrombocythemia. The JAK2 V617F mutation is found in 95% of Polycythemia Vera, and 50% of Essential Thrombocythemia and Primary Myelofibrosis patients. It was thought that the JAK2 V617F mutation and BCR-ABL1 translocation were mutually exclusive; but now a few cases have been reported with both alterations. We report a rare case with the presence of JAK2 V617F mutation, secondary to a diagnosis of BCR-ABL positive chronic myeloid leukemia. The patient was initially diagnosed as chronic myeloid leukemia and was BCR-ABL1 positive, so he started to receive Imatinib. He responded well to the therapy for three years, but after this time the patient had a hematological relapse still with no detectable copies of BCR-ABL1. For this reason, we thought of the possible development of another genetic alteration. Because the patient had a very high platelet count, we decided to look for the JAK2 V617F mutation, which result was positive. This case is just one of the few that have been reported worldwide that have a coexistence of these two genetic alterations: the BCR-ABL1 transcript and JAK2 V617F mutation in chronic myeloproliferative syndromes. This is the first case in the Central American population, found in our series of a total of 168 patients with Philadelphia positive chronic myeloid leukemia.
