Kimura’s Disease: A Diagnostic and Therapeutic Challenge
- 21 Downloads
Kimura’s disease, also known as Eosinophilic Granuloma, is a rare chronic condition seen mainly in Oriental population. It presents with subcutaneous nodules, lymphadenopathy, salivary gland hypertrophy with peripheral eosinophilia and raised serum IgE levels; rarely renal involvement may also be present. Its etiology mainly remains unknown. We present a case series of two patients. Our first case is a middle aged female which presented with a parotid swelling, mimicking a parotid neoplasm. Further investigations revealed associated intra-parotid and cervical lymphadenopathy. An excisional biopsy in the form of Superficial Parotidectomy with lymph node excision was done. Histopathological examination of the excised specimen revealed it to be a case of Kimura’s disease. Our second case, a young adult, presented with a gradually increasing post-auricular swelling. Preliminary investigations in this case pointed towards Kimura’s disease. Excision biopsy of the lesion was done. Histopathological studies confirmed the diagnosis for the same. Both the patients are under our regular follow up and remain disease-free at a follow up of 1 year and 8 months respectively.
