In addition to going to school she works as a waitress and has noted that it is harder to carry heavy trays. She also has gum inflammation and is wondering if this could be related to everything else. The physician notes the heliotrope rash around her eyes (Figure 174-1) and the Gottron papules on the dorsum of her knuckles (Figure 174-2). He considers that this may be dermatomyositis and tests for proximal muscle weakness. The proximal muscles are not found to be weak on physical exam although a subsequent blood test showed a mildly elevated CK and AST. The physician uses his dermatoscope to look at the nail folds and sees many dilated capillary loops (Figure 174-3). On the oral examination, there is a marginal gingivitis and the dermatoscope shows a similar dilated capillary pattern around the tooth. A diagnosis of dermatomyositis is made. The patient was treated with prednisone and hydroxychloroquine and improves greatly. The patient was then tapered off the prednisone fully with no relapse.
