Signs of malignant lymphoma: The signs of lymphoma are variable depending on the location and extent of the lesion. Primary lesions can be found in lymph nodes or in organs other than lymph nodes, such as the tonsils, nasopharynx, gastrointestinal region, spleen, bones, and skin, and extra-nodal lesions are particularly common in non-Hodgkin’s lymphoma. The disease spreads either sequentially from the primary site to adjacent lymph nodes, as in Hodgkin’s disease, or across the neighborhood to distant lymph nodes, as in non-Hodgkin’s lymphoma. Non-Hodgkin’s lymphoma politicians can be multicentric in origin, so the disease often spreads systemically in the early stages. Lymphoma may be associated with a single group of lymph nodes that are enlarged without systemic symptoms, or with generalized infiltration without superficial lymph node enlargement and with corresponding symptoms and signs. The first sign of Hodgkin’s disease is often superficial lymph node enlargement, and only 9% of the cases originate in tissues and organs other than lymph nodes, while non-Hodgkin’s lymphoma is more common outside lymph nodes, and transformation into leukemia is also common.
