The patient was given a diagnosis of dermatomyositis, even though muscle weakness was barely present. FIGURE 1 shows a classic heliotrope rash around the patient’s eyes, which was bilaterally symmetrical. The facial rash was getting worse on her days off because she was spending more time in the sun and the rash of dermatomyositis is often worsened by sun exposure. Hand involvement consisted of Gottron’s papules over the finger joints and ragged cuticles (Samitz sign) (FIGURE 2). The patient had normal muscle enzymes. Her diagnosis could almost be called amyopathic dermatomyositis, which is dermatomyositis without muscle involvement.
The physician started the patient on prednisone 60 mg daily and after 2 weeks the rash was almost completely resolved. The patient was also counseled to avoid the sun when possible, and to use sun protection when outside.
The patient was started on 400 mg hydroxychloroquine daily and in 2 months, the prednisone was completely tapered off.
The physician sent the patient to ophthalmology to have a baseline retinal exam at the time the hydroxychloroquine was started. At 6 months, her eye exam remained normal despite the risk of eye problems from the hydroxychloroquine. A year later, the patient had stopped the hydroxychloroquine and was doing well off the medication. Two years later the patient had a relapse and was treated successfully using the same regimen.
