Cutaneous lymphoma is a common type of disease in clinical practice, and the common symptoms are mainly as follows: a. Redness and pain of the skin, often due to limited proliferation of lymphoma, resulting in greater local skin tension, may be accompanied by significant redness and pain. The redness and swelling will be significantly aggravated if it is accompanied by local skin breakdown or infection and pain. Patients can apply Ruyi Jinhuang ointment and Yu Shiyi ointment to reduce the local redness, swelling and pain. Second, the skin is accompanied by ulcerated spots and papule-like changes. Some patients with lymphoma may have local skin with rupture and local skin bulge-like protrusions, similar to herpes zoster or eczema-like changes, which may easily cause misdiagnosis of the patient’s condition. If necessary, local skin excision is feasible and sent for pathological examination to finally clarify the diagnosis. Once a patient discovers cutaneous lymphoma, it is recommended to visit a hospital as soon as possible to avoid delaying the condition.
