Final answer:
Acute Lymphocytic Leukemia (ALL) presents with symptoms like fatigue, swollen lymph nodes, and loss of appetite, and CBC findings often show an elevated number of immature lymphocytes, as well as decreased red blood cells and platelets.
Step-by-step explanation:
Acute Lymphocytic Leukemia (ALL): Signs/Symptoms and CBC Findings
Acute Lymphocytic Leukemia (ALL) is a type of cancer characterized by the overproduction of immature white blood cells, specifically from the lymphoid line. The signs and symptoms of ALL include fatigue, swollen lymph nodes, loss of appetite, weight loss, fever, and night sweats. These symptoms may often mimic those of a systemic infection. When a Complete Blood Count (CBC) is performed, findings often include an elevated white blood cell count, with a large number of these cells being immature lymphocytes. In addition, there may be a decrease in red blood cells (anemia) and platelets, leading to symptoms such as excessive bleeding and bruising, indicating bone marrow failure.
For the diagnosis of ALL, it is crucial to observe these changes in the context of patient symptoms and follow-up with additional diagnostic tests such as bone marrow biopsies.
