Malignant Lymphoma 恶性淋巴瘤 What is malignant lymphoma? Classification of ML
In this group of lympho-proliferative diseases, normal lymphoid tissue is replaced by abnormal cells of lymphoid origin forming solid malignant tumors of the lymph nodes Malignant lymphoma(ML)
Malignant lymphoma (ML) In this group of lympho-proliferative diseases, normal lymphoid tissue is replaced by abnormal cells of lymphoid origin forming solid malignant tumors of the lymph nodes
Classiffication of ml Hodgkin's lymphoma, HL Non- Hodgkin's lymphoma, NHL
Hodgkin’s lymphoma, HL Classification of ML Non-Hodgkin’s lymphoma, NHL
Hodgkins lymphoma 1. Presence of the distinctive neoplastic R-s cells and non-neoplastic cells usually greatly outnumber the tumor cells 2. Studies show that it is a tumor come of b lymphomacytes

Pathological change of HL Generral features Grossly Microscopically Classification Clinical course
Heneral features 1. a painless enlargenment of the lymph nodes 2. More often in upper half of the body cervical axillary, para-aortic) 3. Initially localized to a single peripheral lymph node region but orderly spread by contiguity nodes 4. Extranodal involvement uncommon
1. a painless enlargenment of the lymph nodes. General features 3. Initially localized to a single peripheral lymph node region but orderly spread by contiguity nodes. 4. Extranodal involvement uncommon. 2.More often in upper half of the body (cervical, axillary, para-aortic)
Grossly 1. The affected lymph node are enlarged, with a smooth surface, and the lymph node capsule is rarely breached 2. Lymph nodes conglutinate to be a fixed, nodular mass 3. Cut surface: white-gray fishy, yellowish necrosis

Microscopically Normal construction of lymph nodes were distroied 2. Characterized morphologically by the presence of distinctive neoplastic giant cells called Reed- Sternberg(Rs)cells; 3, The rs cells admixed with a variable infiltrate of reactive, nonmalignant inflammatory cells;
