The rash associated with lymphoma is not much different from common rashes; they are both characterized by red papules. However, lymphoma is not an isolated disease. For instance, in patients, one can feel lumps on the neck or upper clavicle area, but they may also exhibit systemic symptoms such as fever, night sweats, weight loss, fatigue, lack of appetite, anemia, chest pain, and other symptoms because it is a systemic disease. Thus, it may cause these systemic symptoms. The rash can also cause itching of the skin.
