Abstract:
A case of 54-year-old male who, during the development of a pulmonary fibrosis, showed extrapulmonary autoimmune symptoms (polyarthritis and hemolytic anemia), is presented. The antinuclear antibodies and rheumatoid factor positives have been described in up to 30% of the idiopathic pulmonary fibrosis, complicating the differential diagnosis with lung fibrosis caused by alterations of connective tissue. We discuss the prognosis and treatment of this difficult diagnosis.
