In this interactive, question‑and‑answer style lecture for medical students, Dr. Hassan Bencheqroun reviews the fundamentals of hematology and oncology with a focus on leukemia, lymphoma, and related myeloid disorders. He emphasizes the clinical importance of a single laboratory cutoff—20 % blasts in bone‑marrow or peripheral blood—as the WHO definition that separates acute leukemia from other hematologic conditions. The lecture distinguishes acute myeloid leukemia (AML) from acute lymphoblastic leukemia (ALL) using lineage‑specific markers (myeloperoxidase positivity, hour‑shaped rods for AML; TdT positivity for ALL) and discusses age‑related incidence patterns. Dr. Bencheqroun explains that leukemia and lymphoma are the same malignant clone presented in different anatomic locations, illustrating this with examples such as CLL/SLL and ATLL. He then outlines the characteristic features of Hodgkin lymphoma (CD15⁺/CD30⁺ Reed‑Sternberg cells, bimodal age peaks, B‑symptoms) versus non‑Hodgkin lymphomas. Critical cytogenetic translocations—BCR‑ABL1 (Philadelphia chromosome) in chronic myeloid leukemia (CML), PML‑RARA in acute promyelocytic leukemia (APL), and MYC‑IGH in Burkitt lymphoma—are highlighted as diagnostic hallmarks that dictate targeted therapy (imatinib for CML, ATRA/arsenic for APL). Clinical vignettes reinforce decision‑making: a 34‑year‑old with 24 % blasts is classified as AML; a 45‑year‑old with massive leukocytosis and full maturation spectrum is CML, progressing to accelerated phase when blasts exceed 20 %. The session concludes with key take‑aways: the 20 % blast threshold, lineage markers, the leukemia‑lymphoma spectrum, Hodgkin immunophenotype, and three translocations that change management.
