BackgroundWe reviewed details of Chinese Kimura’s disease (KD) cases. A full clinical analysis was subsequently performed to improve the accuracy of clinical diagnosis and treatment of KD.MethodsA total of 24 patients with pathologically confirmed KD treated between March 2008 and March 2018 were reviewed retrospectively for clinical and histopathological analysis.ResultsIn the 24 KD cases, 20 were male and 4 were female with the age of onset ranging from 5 to 65 years. Lesion diameter ranged from 0.6 cm to 7 cm with unilateral involvement being more popular (79%). Imaging examination had a high detection rate for KD involving the parotid gland and subcutaneous but had low specificity. Microscopic analysis indicated that KD mainly involved subcutaneous soft tissue and lymph nodes. The prominent feature of lymphoid tissue was germinal center hyperplasia surrounded by several lobules associated with hyperplastic vascular structures. Out of the 24 patients, 11 experienced recurrence of disease after treatment (surgical resection: 46.2%, surgical resection followed by oral corticosteroids: 71.4% and surgical resection combined with radiotherapy: 0%).ConclusionsOur analysis revealed clinical, imaging, and histological characteristics of KD. A better understanding of the disease will help clinicians reduce misdiagnosis and improve the diagnostic rate upon patient first clinical visit.
