Summary
Exacerbation of pityriasis rubra pilaris (PRP) with ultraviolet exposure is well recognized. However, the initial presentation of PRP in a photoexposed distribution is infrequently reported, and only rarely confirmed with phototesting. We describe such a case of photosensitive PRP. Phototesting revealed exquisite ultraviolet (UV) sensitivity, which was particularly marked to UVB, a feature shared with previously reported cases.
