Clinical picture of orf in Northern California.

Eighteen cases of orf are reported, six with multiple lesions and twelve with only one. Iridoform bullae were seen in every case, and untraumatized lesions healed without scar. The fingers and hands were involved in fourteen instances, the remainder occurring on the forearms, nose, forehead, and eyelid. Lack of systemic symptoms was usual, although several patients had regional adenopathy, malaise, and fever. Treatment was purely symptomatic, and x-ray therapy was not effective.
