A retrospective study of 20 patients with Kimura’s disease from China

Kimura's disease (KD) is an eosinophilic proliferative lymphoid disease with rare incidence rate and nonspecific clinical symptoms.To investigate the clinical characteristics, diagnosis, treatment, and prognosis of KD.The clinical manifestations, laboratory examination, imaging examination, proposed treatment, and prognosis of 20 patients with KD treated in our hospital were retrospectively analyzed.All cases showed painless masses. The proportion of peripheral blood eosinophils rose in 18 cases (90%), the eosinophil count increased in 14 cases (70%) and the serum immunoglobulin E (IgE) levels were significantly increased in 5 patients (100%). Pathological examination revealed follicular hyperplasia, eosinophils infiltration, and tiny vessels proliferation in KD samples.KD should be considered when the patients suffered head and neck subcutaneous painless mass, increased peripheral blood eosinophils and raised serum IgE level. Pathological examination is the golden standard for diagnosing KD. Surgical intervention, medical treatments, and radiotherapy may be effective for KD treatment.This study might shed a light on improving the diagnosis and treatment for KD.
