What do smudge cells indicate?
What do smudge cells indicate?
Smudge cells are remnants of cells that lack any identifiable cytoplasmic membrane or nuclear structure. Smudge cells, also called basket cells, are most often associated with abnormally fragile lymphocytes in disorders such as chronic lymphocytic leukemia (CLL).
Are smudge cells ever normal?
Many different scenarios can lead to smudge cells on a slide, but because the presence of smudge cells traditionally implies CLL, it is not currently standard practice in the United States to report smudge cells in any context other than CLL, and then usually only as “present,” without quantitation or grading.
Do smudge cells mean cancer?
Background: It is reported that the percentage of smudge cells in the blood smear could be a prognostic indicator in chronic lymphocytic leukemia. However, the clinical significance of smudge cells in other hematological malignancies, solid tumors or non-malignant diseases is less clear.
How do smudge cells occur?
Smudge cells, or basket cells, are remnants of leukocytes. They have no cytoplasm, and sometimes all that can be seen are smashed nuclei. Smudge cells are formed from leukocytes, typically lymphocytes, that are fragile, and are destroyed or smudged in the physical process of making a smear.
How common are smudge cells?
The presence of smudge cells on peripheral-blood smears of CLL patients is a constant feature of CLL with significant interpatient variability. The median smudge cell percentage was 28% (range, 1% to 75%) in our study. Only four patients (4%) had a smudge cell percentage within the 1% to 5% range.
How do you prevent cell smudging?
The “smudge” is condensed nuclear material without identifiable cytoplasm. This artifact can be avoided by adding a drop of serum albumin to four or five drops of blood before making the blood smear.
Is CLL a death sentence?
CLL is not an imminent death sentence, especially now. A significant chunk of us will never need treatment and even more of die with the disease, not from it.
Which leukemia has smudge cells?
Purpose. Smudge cells are ruptured chronic lymphocytic leukemia (CLL) cells appearing on the blood smears of CLL patients. Our recent findings suggest that the number of smudge cells may have important biologic correlations rather than being only an artifact of slide preparation.
Can infection cause smudge cells?
Smudge cells can also be due to infectious causes or simply due to an old blood sample. CLL is recognized based on increased absolute lymphocyte count on CBC.
Can you live 20 years with CLL?
Chronic lymphocytic leukemia (CLL) can rarely be cured. Still, most people live with the disease for many years. Some people with CLL can live for years without treatment, but over time, most will need to be treated. Most people with CLL are treated on and off for years.
Can a person live 20 years with CLL?
The survival rate for people with CLL varies widely according to the stage of the disease (see Stages). The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100. The 5-year survival rate for people age 20 and older with CLL is 86%.
Does CLL ever go away?
What kind of white blood cells are smudge cells?
The peripheral blood smears were confirmed under a microscope, and about half of the white blood cells were smudge cells . Epstein-Barr virus (EBV) virus capsid antigen-IgM was detected (1.6 index, BML, tokyo) and EBV nuclear antigen was not detected.
How are smudge cells related to infectious mononucleosis?
The smudge cells are well studied as a prognostic factor for chronic lymphocytic leukemia, but it is also found in viral infections. We experienced a case of abnormal hyperleukocytosis (WBC 41,600/mm3) associated with infectious mononucleosis (IM).
What is the differential count of smudge cells?
Differential Diagnosis of Smudge Cells. The differential diagnosis of the smudge cells involves counting the lymphocytes to find out its relative differential count. It is usually 0.24 which is sometime represented as 24% of the total number of white blood cells present in the body.
What are the effects of smudge cells in cancer?
Our survey indicated that in all cancers, those who had higher percentage of smudge cells were prone to have poor outcomes when compared with the subjects with lower percentage of smudge cells. This finding was quite different from the results of previous studies in which the race-ethnicity of most …
