A New Case of Childhood Acute Lymphoblastic B-Cell Leukemia from Pristina

Acute lymphoblastic leukemia (ALL) is a malignant disease caused by mutations in B- or T-cell precursors of bone marrow cells. Childhood acute lymphoblastic leukemia (ALL) is a subtype of pediatric cancer with a 1 in 2000 incidence. Here we present a new childhood ALL in a 3-year-old girl. As CD45/19, CD10/19, CD3, CD8, CD10, and CD19 were positive in immunohistochemically analyses of blast cells, a B-ALL was diagnosed with a causative ETV6-RUNX1 gene fusion. The patient was treated based on standard protocols BMF-ALL 2009. Interestingly, an aunt and a grandfather of the patient had experienced malignancies as well, which may be carefully interpreted as a hint on a familial cancer syndrome.
