The early symptoms of lymphoma are not very obvious, most patients will find swollen lymph nodes in the neck, and the texture is hard, some patients may appear clinical manifestations such as low fever and weakness, but dry syndrome is a disease of rheumatic system, the disease itself will also appear low fever and multiple swollen lymph nodes, so these clinical symptoms are often ignored by patients. The chance of dry syndrome complicating with malignant lymphoma is more than 40 times higher than that of normal people, so patients with dry syndrome should pay special attention to the appearance of lymphoma. What to do at this time? Regular ultrasound examination of lymph nodes is needed to understand the local changes of lymph nodes, and blood routine, including liver function, kidney function, immune antibody and other tests should be checked to keep track of the progress of the disease, and if necessary, histological examination of lymph nodes, that is, pathological section examination, should be conducted to make timely diagnosis of the disease.
