Kikuchi disease is a very rare disease, also known as histiocytic necrotizing lymphadenitis. It was discovered in Japan by M. Kikuchi and Fujimoto in 1972. It is relatively common in Japan, occasionally reported in other parts of Asia, very few reports in Europe and North America. The reason of this disease is unclear, and there are two hypotheses of infection and autoimmune. The main symptoms of this disease are fever, swollen lymph nodes, Skin rash and headache. It is easy to be misdiagnosed as lymph node tuberculosis , lymphoma, systemic lupus erythematosus (SLE), etc. Only pathological biopsy can confirm the diagnosis. Western medicine currently does not have specific treatments for this disease, and non-steroidal anti-inflammatory drugs (NSAIDs) can be used to relieve lymph node tenderness and fever. In severe cases, corticosteroids can be applied .
I have treated one case Kikuchi disease with Chinese herbal medicine and acupuncture few months ago. The case report as follows:
Mr. L, Male, 43 years old, married, Asian, Engineer .
Initial consultation: 7th November 2017. Chief Complaint: Right neck lymph node swollen and pain, accompanied night sweats for 3 weeks. The patient found the right submandibular lymph node pain 3 weeks ago; it enlarged gradually, accompanied by headache and fever. His temperature used rise up to 38-39 ℃. He sweating a lot at day and night time. His appetite was reduced, feels slightly nausea. His bowel movement is basically normal and the urine is yellowish. Poor sleep due to night sweat.

Diagnosis of traditional Chinese medicine: LuoLi (瘰疬). Syndrome differentiation: Hyperactivity of fire due to yin deficiency；heat & phlegm accumulating.

Second visit: 1st December, 2017
His heat was reduced; the body temperature dropped below 37 °C. Patient still have over sweating, accompanied by hot flashes in the afternoon, dry mouth. His appetite was better than before. He lost 3 kg body weight. His neck lymph node was as swollen as before. His tongue was red with less coating. Pulse was wiry and rapid. Repeat prescription was given of 7 bags. Acupuncture points were the same as before.
Third visit: 13th January 2018
Sweating and hot flashes significantly improved，temperature back to normal. On 18th December, he underwent lymph node surgery in the hospital. Pathological biopsy didn’t find cancer cells. The pathological diagnosis was: Kikuchi disease. After the operation, the patient felt weakness and exhausted. His tongue was pale and pulse was thready. Modified Danggui Buxue Tang was given to supplement Qi and blood, and to clear the remaining evil. Prescription: Danggui 10g, Huangqi 10g, Baizhu10g, Xuanshen10g, Zhimu 10g, Huangbai 10g, Banzhilian 10g, Fuling 10g, Gouqizi 10g, Gancao 6g. Boiled 1 bag, drink the decoction twice a day for 7 days. Acupuncture points are changed to: Zusanli (ST36), Qihai (RN6), Xuehai (SP10), Zhongwan (RN12), Pishu (BL20), and Shenshu (BL23). Follow-up three months through telephone, the patient didn’t have any symptoms.
Because the reason of Kikuchi disease is unclear, there isn’t any specific treatment in western medicine. A report from Taiwan showed the author use Gegen Tang, Chaihu Guizhi Tang and Shengyu Tang to treat early, middle and later stages of Kikuchi disease . The other report from mainland China showed classic herb formula Yinqiao San also achieved a good effect on Kikuchi disease .
In my case the hot flashes and night sweats indicated yin deficiency and internal heat. The enlarged submandibular lymph node belongs to the "Phlegm core" or "Luoli". According to the diagnosis principle of combine syndrome differentiation and disease, we selected nourishing yin and clearing heat; dissipating phlegm and mass in the early stage of this disease. Modified Qinhao Biejia Tang was applied. In this formula, Qinghao, Digupi,, Qinjiao, Zhimu for clean asthenia heat; Shudihuang, Xuanshen for nourishing kidney yin; Huangqin, Huangbai, Huzhang for clean heat and detoxification; Mudanpi for cooling blood and detoxification.
His fever and night sweats were significantly relieved after treatment. In order to clarify the western medicine diagnosis and exclude the possibility of malignant tumor, the patient underwent lymph node surgery. Pathological biopsy proved the diagnosis. The patient showed the manifestation of qi and blood deficiency after the operation. A modified Danggui Buxue Tang was prescript to benefit Qi and blood, combined with Huangbai, Banzhilian to clean the remained heat. Add Gouqizi for raises the liver and kidney yin; Add Xuanshen for clean heat and dispel mass. After several months of follow-up, the feedback showed a positive result.
Although this disease is a rare disease in western medicine, but its clinical manifestations are very common in Chinese medicine’s opinion. It may shows different syndromes at different stages. If the TCM diagnosis and treatment principle is correct, herb selection acupuncture point selection is accurate, it will achieve very satisfactory treatment results. Discussing Chinese herb treatment on Kikuchi disease, it might widen the clinical vision of both Chinese and western medicine practitioner and explore a new idea for the treatment of this rare disease.
