[Aneurysm of superficial temporal artery in angiolymphoid hyperplasia lesions].

INTRODUCTION: Subcutaneous angiolymphoid hyperplasia with eosinophilia is a disease which usually affects small vessels of neck and facial area. CASE REPORT: A 44 year-old with cutaneous lesions corresponding to angiolymphoid hyperplasia with eosinophilia is reported. The lesions were located near the temporal region. This case was particular because of the development of an anevrism of the superficial temporal artery. DISCUSSION: Involvement of the superficial temporal artery by angiolymphoid hyperplasia with eosinophilia has been reported in only one case which simulated a Horton disease because of an occlusion of the temporal artery. The development of an anevrism of this artery in a patient with angiolymphoid hyperplasia with eosinophilia is a very unusual presentation of the disease which has not been previously reported.
