Itchy neck is not a symptom of lymphoma. The clinical manifestations of lymphoma are complex and diverse. It is usually manifested as superficial lymph node enlargement, and the enlarged lymph nodes are mostly painless, smooth and movable on the surface, tough, full and even when you look at them, and they are usually isolated and scattered under the neck or in the armpit or groin in the early stage, and only in the advanced stage will they fuse with each other, adhere to the skin and become inactive or form ulcers. Patients with malignant lymphoma also have systemic symptoms, such as fever, itching, night sweats, emaciation and other general conditions; some patients may become anemic; patients with malignant lymphoma also have some specific skin manifestations, such as polymorphic erythema, blistering and erosion of the skin, and in advanced stages, patients with malignant lymphoma have very low immune function, and skin infections often break down and ooze. In the advanced stage, patients with sexual lymphoma often have long-lasting skin infections that break down and exude fluid, resulting in scattered skin thickening and desquamation throughout the body. Therefore, the diagnosis of lymphoma cannot be made solely on the basis of itchy neck.
