[Non-giant cell temporal arteritis as a manifestation of Churg-Strauss syndrome. Presentation of a case and review of literature].

Most cases of temporal arteritis are of the giant cell variety, with cases involving other histologic patterns occurring rarely. There are only 4 descriptions in the literature of non giant cell temporal arteritis as a manifestation of Churg-Strauss syndrome. We report the case of a 74-year-old man with a history of bronchial asthma who presented with systemic symptoms and right temporal cephalea with diplopia, diffuse muscle pain and transient skin lesions on the extremities. The right temporal artery was enlarged and painful but pulsatile. Tests showed a high erythrocyte sedimentation rate and leukocytosis with relative and absolute eosinophilia. Biopsy of the temporal artery revealed polymorphic inflammatory infiltration throughout the vas, with numerous eosinophils and non giant cells, confirming a diagnosis of Churg-Strauss syndrome with extension to the temporal artery. Temporal arteritis should be considered a syndrome with variable substrate pathology; the possibility that it is a rare manifestation of systemic necrotizing vasculitis should not be ruled out.
