Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm characterized by overproduction of myeloid white blood cells. Philadelphia chromosome is an essential finding for CML diagnosis. Generally, a clinical diagnosis of essential thrombocythemia (ET) can be established from isolated marked thrombocytosis in peripheral blood. However, Philadelphia chromosome-positivity or bcr/abl rearrangement with isolated thrombocytosis should be diagnosed as CML, not ET, according to World Health Organization diagnostic criteria. Therefore, CML should not be excluded before confirming the presence of the Philadelphia chromosome or bcr/abl rearrangement in cases of isolated thrombocytosis in peripheral blood. We report a case of CML with clinical features of ET in a patient successfully treated with imatinib.

Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
