Association of Acute Lymphoblastic Leukemia with Unilateral Facial Palsy: A Rare Presentation

Acute lymphoblastic leukemia (ALL) is the most common pediatric cancer. Survival probability of pediatric ALL had been 10-20%, but the most recent clinical trials with multiagent chemotherapy have achieved overall survival probability of better than 80%. This is achieved because of better supportive care, treatment stratification based on relapse risk, and the biological features of leukemic cells. Diagnosis of ALL was based principally on morphological identification of leukemic blasts in bone marrow, and immunophenotype assessment by flow cytometry is necessary, and most pediatric ALL cases are clinically classified as B-cell precursor, T-cell ALL, or mature B-cell types.
