A case of CREST syndrome (calcinosis, Raynaud's phenomenon, esophageal hypomotility, sclerodactyly, and telangiectasia) that initially showed Raynaud's phenomenon, sclerodactyly and polyarthralgias, 3 years later completing the process, associated to sicca syndrome, is presented. The esophageal affectation showed a loss of peristalsis of the inferior 2/3, as well as hypotonia of the gastroesophageal sphincter.
