Hodgkin lymphoma in the elderly

Hodgkin's lymphoma (Hodgkinrsquo; s lymphoma) is a unique malignant disease of the lymphatic system, which usually starts in a group of lymph nodes, and then spreads to other lymph nodes or extranodal organs and tissues. Histopathological features are the appearance of malignant Reed-Sternberg cells and an appropriate number of cellular backgrounds. According to its appearance and the relative proportions of Lyssian cells, lymphocytes, and fibrosis, it can be divided into 4 histological types: lymphocytic type, nodular sclerosis type, mixed cell type, and lymphocyte depletion type. Histological subtype is the main factor that determines the clinical manifestations, prognosis and appropriate treatment of patients.
