What kind of rash is this?

I need to know what type of rash is indicated in this case study and what evidence you have to support the reasoning. Thank you!

Case Study

AT is a white woman, age 62, complaining of fatigue, arthralgias of both hips and knees and the small joints of both hands, and a red, scaly rash on her upper torso, extremities, and face. She says that sunlight aggravates the rash and that she has had all of these problems for approximately 2 months, but is most disturbed by the itching rash.  She says the rash has made her very depressed, and she has trouble sleeping at night and concentrating at work during the day.
