Angiolymphoid hyperplasia with eosinophilia masquerading as Kimura disease.

Angiolymphoid hyperplasia with eosinophilia is a rare benign vasoproliferative disease of unknown cause, which can present as tumour-like nodules in the head and neck. We treated a patient who showed some of the features of Kimura disease (KD), which is an important differential diagnosis, because of the latter's association with renal disease.
