A case of bilateral juvenile temporal arteritis
The present case has been reported in the British Journal of Dermatology.

A 23‐year‐old man had (a, b) bilateral temporal nodules. The nodules presented with the appearance of temporal ‘horn growth’. The temporal nodules were fixed to the deep plane. (c) Duplex ultrasonography showed temporal arteritis with segmental thickening and microaneurysms. Hypereosinophilia was noted. (d) Histology showed a parietal and perivascular infiltrate.

After excision of the temporal artery, the course was favourable without treatment. There was no relapse within 3 years of diagnosis. This was a case of bilateral juvenile temporal arteritis (JTA).

JTA affects patients under 40 years of age. It has the appearance of a nodule on the temporal artery, is often unilateral, is not particularly painful and lacks systemic symptoms.

Histology shows intimal hyperplasia with panarteritis with eosinophilic and lymphocytic infiltrate that can extend to the perivascular tissue. Hypereosinophilia is often present without inflammatory syndrome. The course is favourable; relapses are rare. Unlike giant‐cell arteritis, excision is curative in JTA. It is the treatment of choice over steroid therapy.
