#Diagnosis 👉🏻  Chronic lymohoid leukemia


#The_blue_arrows
Smudge cells

#The_black_arrows
Lymphocytes ( mature )

#The_features
- small, mature lymphocytes
- Smudge cells
- Round nucleus, clumped chromatin with only small nucleoli and less cytoplasm


ال clumped chromatin هو عباره عن مجموعه من الكورماتين تجمعت مع بعض

مرفق صورة اوضح توضح شكل clumped chromatin

Chronic Myeloid Leukemia
Is a myeloproliferative disorder characterized by increased proliferation of the granulocytic cell line without the loss of their capacity to differentiate


#The_pathogenesis
حصل  chromosomal translocation من الكرموسوم 9 الى الكرموسوم 22 والذي يسمى ايضاً Philadelphia chromosome ( هو انتقال جينات من الكرموسوم 9 الى الكرموسوم 22 )
فكون oncogene الذي عمل activation لل tyrosine kinase فأثر على نخاع العظم فصارت الخلايا تنتج بشكل كبير جداً

وتمثل نسبة هذا النوع من السرطان 20% فقط


The CML Occurs in 2 different phases
- Chronic phase or crisis
- blast phase or crisis


ونفرق بينهم من خلال الاتي
Chronic phase (CP)
• Leukocytosis (usually 12 - 1,000 x 10⁹/L, median: ~ 80 x 10⁹/L)
• < 2% blasts in blood
• < 5% blasts in bone marrow


Blast phase (BP)
• ≥ 20% blasts in marrow or blood or the presence of an extramedullary proliferation of blasts

اي ان الخلايا immature تكون اكثر من mature بعكس في المرحلة المزمنة تكون immature cell قليلة جداً
