Anti-MDA-5 Dermatomyositis With Development of Drug-Mediated Necrolytic Skin Lesions.

A 59-year-old male presented with 1 month of progressive dyspnea, 30-lb weight loss, and skin changes on the digits of the hands. In the 4 weeks prior to admission, he was admitted and treated twice for pneumonia at another hospital and received intravenous (IV) vancomycin, ceftriaxone, and azithromycin for a total of 10 days. After admission, he underwent computed tomography imaging of chest, which revealed findings suggestive of interstitial lung disease but given the fact that infection was not ruled out, empiric antibiotics were initiated.
