Abstract
Angiolymphoid hyperplasia with eosinophilia (HALE) is a rare, benign proliferative vascular disorder of unknown etiology which typically presents as tumor-like nodules of the skin or subcutaneous tissue. It concerns mostly young female adults. We report a case of HALE located on the ear auricle diagnosed by biopsy. The outcome was total regression.An 81-year-old male patient presented with a lesion of the whole ear auricle. A diagnosis of HALE was confirmed histologically on biopsy. The evolution was marked by spontaneous and complete regression in 2 months. There was no recurrence after 1 year of follow-up.The etiology of this disease remains hypothetical. It poses real diagnostic problems with other types of proliferation, but its main differential diagnosis is Kimura disease. Its treatment has not been codified yet. Spontaneous regression is possible and justifies following the patient from 3 to 6 months, before a possible surgery.
