Abstract
BACKGROUND: Leukemia is a disease in which hematopoietic stem cell mutation leads to the uncontrolled growth of immature blood cells. These abnormal cells, which displace healthy cells, are the reason for the bone marrow's failure and demise. OBJECTIVE: To report unnoticed cases of delayed Leukemia in two patients. CASE REPORT: A 9-year-old male and 14-year-old female born to a non-consanguineous marriage presented with oral manifestations after getting dental treatment in their native place. Acute Leukemia was suspected based on their total blood count. CONCLUSIONS: Understanding the unusual symptoms and signs of acute Leukemia aids in early identification and effective patient care. Key words:Hematologic Neoplasms, Classification, Incidence, Diagnosis, Child, Young Adult.
