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.
