Hodgkin’s lymphoma (lymphogranulematosis) is a type of blood cancer that develops from B-lymphocytes. In lymphogranulematosis, a special kind of cell, Reed-Sternberg cells, can be seen under the microscope. These are large cells that have two nuclei and resemble the eyes of an owl. It is because of these cells that Hodgkin’s lymphoma can be distinguished from other lymphomas.
Hodgkin’s lymphoma can develop at any age, including childhood, and is more common in men.
