What type of abnormal cells is generally observed in chronic lymphocytic leukemia (CLL)?

Chronic lymphocytic leukemia (CLL) is characterized by the accumulation of small, mature lymphocytes in the peripheral blood, bone marrow, and lymphoid tissues. One specific type of abnormal cell that is commonly observed in blood smears of patients with CLL is known as "smear cells." These cells appear fragile and distorted, often resulting from the way they are handled during the preparation of the blood sample. As the blood is smeared on a slide, these lymphocytes may rupture or become deformed, leading to the appearance of "smear cells."

The unique characteristics of smear cells—where these lymphocytes seem to have a "smudged" or blurred appearance—play a significant role in the diagnosis of CLL and distinguish it from other blood disorders. Recognizing these cells during a microscopic examination is vital for healthcare professionals in confirming a CLL diagnosis.

On the other hand, target cells, Heinz bodies, and Auer rods are associated with different hematological conditions. Target cells are related to disorders such as liver disease, hemoglobinopathies, or postsplenectomy states. Heinz bodies are formed due to oxidative damage to hemoglobin and are typically seen in conditions like G6PD deficiency or after exposure to oxidizing agents
