Abstract
Purpose: Kimura's disease is a relatively rare head and neck tumor that frequently occurs in young orientals accompanied with eosinophila. We shared our experience of two cases of Kimura's disease, treated by radical resection and post operative steroid therapy, so we report the correlation of eosinophil counts and disease progression. Methods: A 25 years old male came to the clinic with a mass localized to the right cheek inferior to the right auricle. We could not resect the mass totally. During the follow up period, we checked the eosinophil counts, and steroid therapy was started 7 months after the surgery. A 34 year old female came to the clinic with a mass localized inferior to the left auricle reaching from the posterior portion of the auricle to the left temporal portion. We tried to remove as much tumor as possible, save the temporal region, in regard to the impairment of blood supply to the auricle. After operation, steroid therapy was started. Results: In the first case, the tumor was easily approachable, and radical resection of the tumor with post operative steroid therapy was an effective treatment. In tumors located at difficult regions to remove, as in the second case, optimal debulking and post operative steroid therapy was also effective in treating Kimura's. There were no recurrences in both cases. Eosinophil counts were always reduced after surgery and steroid therapy, and during the period with low eosinophil counts, there was no recurrence of Kimura's disease. Conclusion: Surgery and post operative steroid therapy were effective in treatment of Kimura's disease, and we could assume eosinophil counts as a good indicator for evaluation of the prognosis of Kimura's disease during the follow up period.
