<prompt> A 15-year-old boy presented with one day history of bleedig gums, subconjunctival bleed and purpuric rash. Investigations revealed the following results:Hb-6.4 gmdL; TLC-26,500mm3 Platelet 35,000 mm3; prothrombin time-20 sec with a control of 13 sec; partial thromboplastin time-50sec; and Fibrinogen 10ingdL. Peripheral smear was suggestive off acute myeloblastic leukemia. Which of the following is the most likely -Myeloblastic leukemia without maturationMyeloblastic leukemia with maturationPromyelocytic leukemiaMyelomonocytic leukemia  <response>: The child presents with acute onset of bleeding, along with the following laboratory anamolies.Thrombocytopenia iii Increased partial thromboplastin time.Increased prothrombin time iv Decreased FibrinogenThese hematological abnormalities indicate Disseminated intravascular coagulationThe peripheral blood smear of the patient is suggestive of acute myeloblastic leukemia mentioned in the questionThe AML most likely to occur in this setting is promyelocytic leukemia as it is the most common myeloid leukemia associated with DIC.Promyelocytic AML-M3 leukemic promyelocytes liberate tissue thromboplastin leading to disseminated intravascular coagulation.
