The present study describes a 7-year-old male child who had attended the Pediatric Oncology Clinic of the Regional Cancer Centre, Thiruvananthapuram, Kerala, India, and was pathologically confirmed to have B-Acute Lymphoblastic Leukemia (B-ALL). Conventional cytogenetics analysis at diagnosis showed the presence of a double Philadelphia chromosome and the karyotype of the case was 47, XY, t(9;22)(q34;q11.2), + der(22)t(9;22). FISH, done as a molecular confirmation of the translocation, t(9;22)(q34;q11.2), and this case showed an additional fusion signal that confirms the presence of double Ph. As far as we are aware, this represents the initial and only occurrence of an abnormality report regarding the double Philadelphia chromosome in pediatric B-ALL within India. The double Philadelphia chromosome in B-ALL has a very poor prognosis despite aggressive treatment with chemotherapy. This study reveals the importance of conventional and molecular cytogenetic analysis in risk stratification and prognosis prediction of pediatric B-ALL. The risk stratification based on the conventional and molecular cytogenetic analysis may be taken into consideration for deciding the treatment strategy for each patient.
