Primary biliary cirrhosis and CREST syndrome.

of the skin folds of her face and a lack of ability to open her mouth. Her limbs showed sclerodactyly and isolated telangiectases (Fig. 1a). She had positive anticentromere antibody. She was evaluated because of dysphagia with solids, pyrosis and regurgitation. The esophageal manometry showed a hypotensive lower esophageal sphincter and peristaltic waves of low amplitude in the body of the esophagus. The upper gastrointestinal endoscopy was normal. She referred fatigue and liver tests showed a cholestatic pattern with high serum levels of alkaline phosphatase and gamma glutamyl transpeptidasa. She had high titers (1:320) of antimitochondrial antibody (AMA) and the serum levels of IgM were also elevated (512 mg/dL). Liver biopsy revealed a moderate periportal inflammatory infiltration and bile duct proliferation consistent with the stage II of the Scheuer’s classification of primary biliary cirrhosis (PBC). The hands X-ray showed massive deposits of material of calcium density inside the thumb (Fig. 1b). In the limited cutaneous systemic sclerosis (CREST syndrome –calcinosis, Raynaud’s phenomenon, esophageal dysfunction, sclerodactyly and telangiectasia), there is an excessive amount of collagen deposited mainly in the skin. In advanced stages of the disease, the synovial membrane of the joints, the tendon sheaths and the fascias, develop fibrin deposits that trend to evolve to fibrosis and finally to produce dystrophic calcifications (calcinosis). The occurrence of calcinosis and telangiectasia have been more frequently described in patients with CREST syndrome when it was associated with PBC in comparison with those who did not show this syndrome.
