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
