Kimura's disease with prolonged history and prominent vascular involvement.

Sir, Kimura’s disease (KD) is a well-established entity, which usually occurs as post-auricular nodules with massive eosinophilic infiltration, lymphoid follicle formation and vascular hyperplasia (1–3). Its histopathological findings resemble those of angiolymphoid hyperplasia with eosinophilia (ALHE), which was once considered synonymous with KD, but is now known as a different entity (2, 3). ALHE has vascular involvement including endothelial hyperplasia with atypical endothelial cells, and some cases have been reported with vasculitis. KD rarely shows vasculitis (2, 3). We report here a case of prolonged history of eosinophilia with subcutaneous infiltration on the lower back showing massive vascular involvement, and lymphoid follicle formation with prominent eosinophilic infiltration, which suggested the diagnosis of KD.
