Lymphomas are a heterogeneous group of diseases with various histological signs which are different in clinical course and prognosis. They all are divided into main groups: B-cell lymphoproliferative diseases, Т-cell lymphoproliferative diseases, Hodgkin disease. The first two groups (excluding leukoses) are defined as "non-Hodgkin lymphomas” (NHL). They are about 5–6% of all malignant neoplasms and in their structure they occupy the fifth position in overseas countries.
