According to the American College of Rheumatology (ACR), features characteristic for scleroderma are divided into the following 2 groups (systemic sclerosis is diagnosed when a patient has 1 major and 2 minor criteria.):

  • Major features include centrally located skin sclerosis that affects the arms, face, and/or neck.

  • Minor features include sclerodactyly, erosions, atrophia of the fingertips, and bilateral lung fibrosis.
