Since the publication of the paper of Lamb, Jones, and Maxwell1 on solar dermatitis there have been inquiries in regard to the case reported whose colored photographs showed severe erythema perstans from fluorescent lighting and to the possibility that blue-light sensitivity might account for some of those cases of polymorphic light eruptions which do not seem to improve with use of the antimalarials.
McNairy2 queried how to proceed with an erythematous type of polymorphic lightsensitive eruption in an 18-year-old girl, a rather severe asthmatic who was being maintained with 15 mg. prednisone (Meticorten). When she was first seen she exhibited a cutaneous sun reaction of one year's duration.
