Lymphoma (synonym: limfozitami, lymphadenoma) - conditional collective term describing the pockets of neoplasms of lymphoid tissue in the lymph nodes or in other organs and tissues.
Lymphomas are divided into benign and malignant. The latter represent a true neoplasm of lymphoid tissue, is primarily a system of order. However, the term " lymphoma" refers to another and education, resulting from reactive processes (so-called simple lymphoma, lymphoma simplex).
Simple lymphoma (Fig) is a limited infiltration by lymphoid cells with more or less pronounced bright centers of reproduction, morphologically identical lymph follicles. The origin of its link: 1) with chronic inflammatory processes in organs and tissues; 2) with the processes of regeneration of lymphoid tissue; 3) with symptoms of lymph.
Some researchers believe that education lymphomas in tissues or organs is morphological expression of the extent of immunological tension of the body.
Benign lymphoma is an intermediate form between simple and malignant L. and is characterized by neoplasm of lymphoid tissue in the lymph nodes (usually cervical, submandibular, axillary, inguinal). These tumors have nodular form dense on palpation, grow very slowly, clinically asymptomatic. The origin of benign L. associated with chronic inflammation. Histological examination of benign L. is a simple lymphoma in light of chronic nonspecific pneumonia.
the usual structure of lymph nodes with multiple enlarged follicles, with big bright centers of reproduction. Sinuses lymph nodes are not differentiated, their place is occupied hyperplastic lymphoid tissue, which makes this type of lymphoma tumors.
Malignant L. observed with systemic diseases of blood-forming system, can be common and limited (see Leukemia, Lymphoma gigantopithecus, Chlamydia).
