[Association of Sjögren's syndrome and mixed connective tissue disease (Sharp's syndrome) in an adolescent (author's transl)].

The authors present the case of an adolescent who, despite his youth and relatively unaffected lacrimo-salivary secretion, was classified within the context of Sjögren's syndrom on the basis of paraclinical investigations, in particular the detection of salivary and lacrimal immunoglobulins. During a long course, the progresssive appearance of new lupoid type signs led to further complex immunological examinations, including examination for anti-E.C.T. antibodies. This case would appear to be an incomplete Sharp's syndrome and should be classified amongst the mixed connective tissue diseases.
