Lymphoma can develop in many different parts of the body and lymph nodes, with the most common being the enlargement of superficial lymph nodes, such as those in the neck, armpits, and groin. The pharyngeal lymphatic ring, including places like the oropharynx, base of the tongue, and tonsils, also commonly exhibit lymph node enlargement in cases of lymphoma. Additionally, lymphoma frequently occurs in the nasal cavity and the mediastinum in the chest, as well as in the abdomen, including lymphomas of the gastrointestinal tract and primary lymphomas of the liver and spleen, and even the retroperitoneal mesentery and pelvic lymph nodes. The skin and bone marrow can also be primary sites for lymphoma. Thus, it can affect multiple parts of the body, with many areas being susceptible to lymphoma.
