Which condition is characterized by a combination of pancytopenia, hepatosplenomegaly, and disseminated intravascular coagulation (DIC)?

• A. Acute lymphoblastic leukemia
• B. Acute promyelocytic leukemia
• C. Chronic myeloid leukemia
• D. Chronic lymphocytic leukemia

Answer: (B)

The condition characterized by a combination of pancytopenia, hepatosplenomegaly, and disseminated intravascular coagulation (DIC) is indeed acute promyelocytic leukemia (APL). APL is a subtype of acute myeloid leukemia (AML) that is particularly notable for its association with bleeding complications due to coagulopathy, specifically DIC. In APL, the presence of the promyelocyte with heavy granulation leads to a unique set of clinical symptoms. The excessive promyelocytes can disrupt normal hematopoiesis, leading to pancytopenia, which is a reduction in all three blood cell types: red blood cells, white blood cells, and platelets. Furthermore, patients with APL frequently exhibit hepatosplenomegaly due to the infiltration of leukemic cells in the liver and spleen, contributing to splenic enlargement and hepatic dysfunction. DIC is a critical and life-threatening complication associated with APL. The high levels of tissue factor released from promyelocytes trigger a cascade of coagulation, which leads to a consumption coagulopathy characterized by both thrombocytopenia and a large number of small blood clots. This results in an increased risk of bleeding, which is one
