[ 2][ 8] Early on, there are typically no symptoms. [ 2] Later, non-painful lymph node swelling, feeling tired, fever, night sweats, or weight loss for no clear reason may occur ...
A complete blood count ( CBC ), also known as a full blood count ( FBC ), is a set of medical laboratory tests that provide information about the cells in a person's blood. The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood ...
Döhle bodies are light blue-gray, oval, basophilic, leukocyte inclusions located in the peripheral cytoplasm of neutrophils. They measure 1–3 μm in diameter. Not much is known about their formation, but they are thought to be remnants of the rough endoplasmic reticulum. [citation needed] They are named after German pathologist, Karl ...

Richter's transformation (RT), also known as Richter's syndrome, is the conversion of chronic lymphocytic leukemia (CLL) or its variant, small lymphocytic lymphoma (SLL), into a new and more aggressively malignant disease. [ 1] CLL is the circulation of malignant B lymphocytes with or without the infiltration of these cells into lymphatic or ...
A white blood cell differential is a medical laboratory test that provides information about the types and amounts of white blood cells in a person's blood. The test, which is usually ordered as part of a complete blood count (CBC), measures the amounts of the five normal white blood cell types – neutrophils, lymphocytes, monocytes, eosinophils and basophils – as well as abnormal cell ...
