Abstract
Clinically amyopathic dermatomyositis (CADM) is a rare subtype of dermatomyositis that presents with cutaneous features and no muscle involvement. This case report describes a 26-year-old woman with recurrent and multiple digital ulcerations coinciding with the start of winter each year. There was no evidence of myopathy, and antibody testing yielded negative results. A diagnosis of CADM was ultimately made based on clinicopathologic correlation. The patient's ulcers demonstrated excellent response to a combination therapy of hydroxychloroquine and potent topical and systemic steroids. Herein, the authors discuss the pathologic and immunologic characteristics of CADM.
