Bilateral Involvement of Juvenile Temporal Arteritis with Eosinophilia: A Rare Case / 대한피부과학회지

ABSTRACT

Juvenile temporal arteritis (JTA) is a non-giant cell inflammation of the temporal artery, characterized by eosinophilic infiltration. It generally affects both adolescents and young adults. JTA is clinically represented by an asymptomatic, palpable lump in the temporal area, with no associated signs, such as fever, myalgia, or visual symptoms. A 38-year-old female presented to our hospital with a history of bilateral linear plaques in both temporal areas for 3 months. Histopathological findings of the right temporal lesion showed infiltration of eosinophils and lymphocytes in the arterial wall and intimal hyperplasia but no giant cell or granulomatous lesions. Doppler ultrasonography revealed a tortuous tubular anechoic lesion, with non-visualization of internal vascular flow. Laboratory findings highlighted eosinophilia of up to 13.8% and a total immunoglobulin E level of 1,182 IU/mL. Here, we report a rare case of bilateral JTA with eosinophilia.
