Angiolymphoid Hyperplasia with Eosinophilia (ALHE): A Diagnostic Dilemma

Abstract

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a benign vaso proliferative disease of undetermined origin. It presents with painless, vascular nodules in the dermal and subcutaneous tissues of the head and neck, particularly around the ear. It is thought to arise due to a atopic hypersensitivity reaction. The lesion is often confused with other possible causes of similar lesions like mesenchymal tumour of the vessels, nerves or muscles in the head and neck, Kimura's disease etc. Complete excision and follow-up is the treatment of choice which is associated with a 33% recurrence rate. We are presenting a case of ALHE which presented mimicking a vascular malformation in the pretemporal region in a 26 year old male.
