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. (B) Percentage of smudge cells in CD38– and CD38+ patients.
What are smudge cells indicative of?
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).
Do smudge cells always mean leukemia?
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.
What is a normal lymphocyte percentage in child?
Normal Results Neutrophils: 40% to 60% Lymphocytes: 20% to 40% Monocytes: 2% to 8%
What are the symptoms of leukemia in a child?
What are the symptoms of leukemia in children?
- Pale skin.
- Feeling tired, weak, or cold.
- Dizziness.
- Headaches.
- Shortness of breath, trouble breathing.
- Frequent or long-term infections.
- Fever.
- Easy bruising or bleeding, such as nosebleeds or bleeding gums.
What does it mean when a child’s white blood cell count is high?
Infection. A higher-than-normal white blood cell count usually means you have some type of infection. White blood cells are multiplying to destroy the bacteria or virus.
Why do smudge cells form?
Smudge cells are formed from leukocytes, typically lymphocytes, that are fragile, and are destroyed or smudged in the physical process of making a smear.
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.
What is the life expectancy of someone with chronic lymphocytic leukemia?
The prognosis of patients with CLL varies widely at diagnosis. Some patients die rapidly, within 2-3 years of diagnosis, because of complications from CLL. Most patients live 5-10 years, with an initial course that is relatively benign but followed by a terminal, progressive, and resistant phase lasting 1-2 years.
What causes smudge cells?
When an external pressure is applied, the thin cytoplasmic tends to get crushed as it is unable to take the pressure. This leads to the formation of smudge cells. One of the most common causes behind the formation of the smudge cells is the preparation of the blood films.
What do smudge cells mean?
smudge cells. immature leukocytes of any type that have undergone partial breakdown, during preparation of a stained smear or tissue section, because of their greater fragility; smudge cells are seen in largest numbers in chronic lymphocytic leukemia.
Are smudge cells normal?
Smudge cells are not unique to CLL. They are seen much commonly and in much higher numbers in CLL. The count in normal specimens may be 0.01 percent, severe infections or burns it may be 0.1 to 0.3 percent. In patients with acute leukemias it may be 1 to 3 percent but in CLL patients it may be up to 20 percent of all cells or higher.
What are smudge cells CLL?
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).
