Lymphomas are a heterogeneous group of neoplastic diseases, the source of which are the reticuloendothelial and lymphatic systems. The main types of lymphomas are Hodgkin's lymphoma and non-Hodgkin's lymphomas.
Once upon a time, lymphomas were considered diseases completely different from leukemia. However, a better understanding of cell markers and the mechanisms of their evolution has shown that differences between these two nosological forms are often absent. The position that lymphoma is relatively limited by the lymphatic system, and leukemia by the bone marrow, is also not always true.
Comparison of hodgkin's lymphoma and non-Hodgkin's lymphoma
Hodgkin's lymphoma |
Non-Hodgkin's Lymphoma |
It is localized in a specific group of lymph nodes |
Typical is dissemination in more than one group of lymph nodes |
Ordered distribution, usually in adjacent zones |
Distribution is disordered |
As a rule, it does not affect the Valdeier rings and mesenteric lymph nodes |
Usually affects mesenteric lymph nodes and can affect the Valdeier ring |
Uncharacteristic of extranodal zones |
Extranodal zones are often affected |
Usually diagnosed in the early stages |
As a rule, it is diagnosed in a common stage |
Children are more likely to have favorable histological variants |
Children usually identify high-grade malignancies |
