Angiolymphoid Hyperplasia with Eosinophilia with Clinical Presentation Concerning for Juvenile Temporal Arteritis

Abstract

A 20-year-old boy presented with a mass superotemporal to the right eyebrow of 1 month's duration without a history of recent trauma. Complete examination and workup, including laboratory analysis, Doppler ultrasound imaging, and magnetic resonance imaging, suggested a diagnosis of juvenile temporal arteritis. Excisional biopsy and histopathology contradicted the preoperative workup and yielded the final diagnosis of angiolymphoid hyperplasia with eosinophilia, a rare eosinophilic dermatosis of unknown etiology. This case highlights the need for better characterization of temporal vascular tumors in the pediatric population.
