Skin symptoms caused by lymphoma are mainly itching and rash. Lymphoma is medically known as malignant lymphoma, which is a malignant tumor occurring in the lymphatic tissue of the whole body. The most common skin symptom caused by lymphoma is itchy skin, which may be itchy all over the skin or localized. Except for cutaneous lymphoma, patients usually do not have a rash appearing on the skin surface. Itching of the skin is common in patients with Hodgkin’s lymphoma and is less common in non-Hodgkin’s lymphoma. In case of skin lymphoma or lymphoma invading the skin, in addition to itching, a rash will appear, including skin erythema, blisters, and wind masses, and even skin ulcers, ulceration, and blood oozing can be seen. Patients can feel lumps under the skin or on the surface of the skin, and there is usually no obvious pain. Repeated rashes and ulcers complicated by skin infections can lead to local skin thickening and peeling.
