[Multiple gangrenous lesions of the scalp in a case of cranial arteritis].

A case of a patient with headache, visual deficiency in his left eye quickly worsening up to blindness and ischemic necrosis in the scalp regions supplied by the superficial temporal arteries, is reported. This acute gangrene began as a bandlike ischemic lesion in the temporo-parietal regions of both sides, rapidly enlarged, and acquired bizarre irregular outlines. Laboratory investigations and particularly superficial temporal artery biopsy confirmed the diagnosis of Horton's temporal arteritis, in accordance with the anamnestic and clinical data assessed at admission.
