ICD-10-AM Code C92.1
This is a malignant neoplasm of white blood cells, involving increased and unregulated production of the myeloid line of cells (predominantly neutrophils, but also basophils and eosinophils) in the bone marrow. It is associated with specific gene abnormalities.
Confirming the diagnosis
Confirmation of the diagnosis is typically based on findings from bone marrow aspiration and biopsy together with genetic testing.
The relevant medical specialists are a haematologist and a pathologist.

# non-SOP condition
The condition may be asymptomatic and first suspected following a blood test. Symptomatic presentations may include fatigue, weight loss, bleeding episodes, excessive sweating and abdominal fullness. An enlarged spleen may be found on examination. Average age of onset is around 60 years old.
The only SOP worsening factor is for inability to obtain appropriate clinical management. The condition is potentially curable with a hematopoietic cell transplant. The condition can now also be controlled long term (without cure) using tyrosine kinase inhibitors.
