Juvenile temporal arteritis
Synonyms: JTA | Non-giant cell granulomatous temporal arteritis with eosinophilia
Juvenile temporal arteritis (JTA) is an extremely uncommon vasculitis of unknown etiology. Eleven documented cases have been reported in the literature affecting older children and young adults. In contrast to the classic form of temporal arteritis it is not a systemic disease nor does it cause local symptoms at the temporal area. The term JTA was coined by Lie and his colleagues in 1975 when they reported four cases of an otherwise asymptomatic disease presenting with a painless nodule at the temporal region. None of the cases showed evidence of systemic disease or history of trauma to the temporal region. Excisional biopsy of the lesions revealed a non-giant cell granulomatous inflammation of the temporal arteries with eosinophilic infiltration intimal proliferation and microaneurysmal disruption of the media. JTA has a benign clinical course is treated by surgical excision and does not recur.

Patients must be seeking help with any of the following needs related to their diagnosis: • Accessing prescribed healthcare, including understanding their healthcare benefits • Issues related to their health insurance benefits, including denials of care, out-of-pocket costs, network issues, and insurance options • Financial concerns, including cost-of-living expenses and medical expenses • Practical needs, including transportation and nutritional needs • Assistance with filing an application for disability Since its inception, PAF has provided direct, sustained patient assistance to more than 1.7 million patients and touched many more through its website and outreach events. Amongst the more common issues that patients and caregivers call PAF for help with include the inability to afford transportation expenses, inability to afford rent/mortgage, inability to afford their co-pay for medications, and inability to afford utilities and resulting shut-off notices. PAF serves patients with numerous health conditions, the majority of which have some form of cancer. Non-cancer diagnoses included rare diseases, chronic and debilitating conditions, nervous system conditions, cardiovascular conditions and vascular disease, autoimmune diseases, and diabetes. PAF solicits and receives donations to its programs from a multitude of sources including government agencies, non-profit organizations and for-profit organizations in the healthcare sector, including pharmaceutical manufacturers and healthcare providers.
