CHIEF COMPLAINT: Rash on the body
CLINICAL HISTORY: In August, a 37-year-old Caucasian female (Fitzpatrick skin type 2) with a past medical history of depression, DJD, and spinal stenosis, presented for consultation regarding a five year pruritic rash over her face, neck, chest, shoulders, and arms. She was seen one month ago by her primary care physician, who performed lab work which showed an elevated CRP 31.3 (normal 0-5mG/L), normal CBC w/diff and negative ANA. She was placed on a 7 day prednisone taper and OTC loratidine. Her symptoms had mild short term relief and then promptly returned. She reports suffering from similar lesions over the last five years which have waxed and waned in intensity. She denies any new recent medications or herbal supplement additions. She cannot specifically associate the lesions with sun exposure. She denies any systemic symptoms, other than low back pain which has been an ongoing issue for several years. She is an active one pack per day smoker and occasional social drinker, denies any illicit or recreational drug use.
