Article Synopsis
  • Chilblain-like lesions became common during the COVID-19 pandemic, but their connection to SARS-CoV-2 infection is still unclear.
  • A study at a hospital in Italy involved 17 adolescents with these lesions to examine their characteristics and possible links to the virus.
  • Results indicated that while the lesions had distinct features, extensive testing showed no evidence of SARS-CoV-2 infection, suggesting that these skin manifestations are not associated with the virus.

Dermatomyositis (DM) is an autoimmune disease that primarily affects the skin and muscles, but may also have a systemic involvement. The frequency of scalp involvement in DM varies from 28 to 82% and is often encountered as part of a DM flare. However, it frequently presents as a treatment-resistant disease, and patients reporting no improvement with conventional therapies require further investigation.
