DaveAbstract Kimura’s disease is a rare inflammatory disorder of unknown cause, primarily seen in youngAsian males. The disease is characterized by a triad of painless subcutaneous masses in head and neckregion, blood and tissue eosinophilia and moderately elevated serum immunoglobulin E levels. Here, wepresent a case report of this rare entity of unusual age presentation with classical histopathogical features.Key Words: Kimura’s Disease; Eosinophilia; Parotid Gland; Lymphadenopathy Received on: 22/09/2010 Accepted on: 06/12/2010Introduction Kimura’s disease (KD) is a rare chronic number. The histopathological feature ofangiolymphoid proliferative soft tissue disorder excisional biopsy was matched with that ofof unknown origin.(1) It occurs most often in incisional one. The patient was supplementedyoung and middle aged asian male. It is most with oral Dexamethasone for total duration of 6common in head and neck region, with a weeks (0.5 mg twice daily for 1 week and thenpredilection for preauricular area. Typical tapered over 5 weeks). The patient wasclinical presentations are painless subcutaneous apparently normal without any local recurrencemasses, regional lymph node enlargement, blood & systemic involvement within 6 month ofand tissue hyper eosinophilia, and markedly follow-up period.elevated serum IgE levels.(1) According to the Discussionprevious medical literatures, Kimura’s disease Kimura’s disease first described in1937has a high recurrence rate so early & definitive in Chinese literature by H.T.Kimm and C.Szetodiagnosis of the disease is vital for effective and they termed it as “eosinophilic hyperplastictreatment plan.(1) Here we report a case of lymphogranuloma”.(2) The disease becameKimura’s disease with clinico-pathological widely known as Kimura’s disease after Kimuradifferential diagnosis. and colleagues reported two cases of unusualCase Report granulation combined with hyperplastic changes A 65 year old man reported to of lymphoid tissue.(1) The etiopathogenesis ofoutpatient department with chief complaint of KD remains unknown and it is consideredpainless swelling on right side of face in parotid nowadays as an allergic disease and it seems toregion since 4 months but it was painful on be a systemic immunological disorder.mastication.
