The initial rash (without weakness) 2 months prior was thought to be a photosensitivity reaction to her new hydrochlorothiazide (HCTZ) prescription. She stopped the HCTZ and the rash initially improved with some topical corticosteroids. At the time of her current presentation, she had trouble getting up from a chair, walking, and lifting her arms over her head. The rash was prominent in sun-exposed areas, but was also seen in a shawl-like distribution in non–sun-exposed areas (Figure 189-1). Aside from her hypertension and obesity, the patient did not have any previous chronic medical conditions. She was afebrile with no other pertinent findings on physical exam.
