Summary
Chronic myeloid leukemia (CML) can rarely mimic essential thrombocythemia (ET) at onset. Testing for the Philadelphia chromosome and bcr/abl fusion gene is crucial for accurate diagnosis and treatment.
Area of Science:
- Hematology
- Oncology
- Molecular Biology
Context:
- Chronic myeloid leukemia (CML) is a myeloproliferative neoplasm characterized by the Philadelphia chromosome (Ph).
- Essential thrombocythemia (ET) is another myeloproliferative neoplasm characterized by elevated platelet counts.
- Distinguishing between CML with thrombocytosis and ET is critical for appropriate management.
Purpose:
- To investigate the clinical, pathological, and biological features of a rare CML presentation mimicking ET.
- To highlight the diagnostic challenges and importance of molecular testing in such cases.
Summary:
- A case of CML presenting with marked thrombocytosis, mimicking ET, was analyzed. Morphological examination showed thrombocytosis and moderate leukocytosis.
- Cytogenetic and molecular analyses confirmed the presence of the Philadelphia chromosome and bcr/abl fusion gene, confirming CML.
- This Ph+ ET can progress to accelerated phase or blast crisis, with a tendency towards myelofibrosis and blastic transformation.
Impact:
- Routine cytogenetic and molecular analysis are essential for diagnosing CML cases that mimic ET.
- Early and accurate diagnosis is vital, especially with the availability of targeted therapies like imatinib.
- All suspected ET cases should be screened for the Philadelphia chromosome and bcr/abl transcript to prevent misdiagnosis and ensure timely intervention.

01:27Disorders of Leukocytes
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
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 system...

01:24Graves Disease II: Pathophysiology
Graves’ disease is an autoimmune disorder characterized by the production of thyroid-stimulating immunoglobulins (TSI) that activate TSH receptors, leading to excessive synthesis and release of thyroid hormones (T3 and T4) and resulting in hyperthyroidism.Among all causes of hyperthyroidism, Graves’ disease is the most common and can happen at any age, though it is more frequent in women. It produces a hypermetabolic state with features such as weight loss, tachycardia, tremor, and heat...
01:24Chronic Kidney Disease II: Clinical Manifestations
Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...
01:24Disorders of Hemostasis
Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.

02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
