[Diffuse interstitial lung disease and connective tissue diseases: study of seven cases in Dakar].

INTRODUCTION: The diagnosis of diffuse interstitial lung disease non specific in connective tissue disease is difficult because of many differential diagnoses. Lung involvement can affect functional or vital prognosis. We report 7 cases. CASES: We collected data from 60 years old mean patients. Pulmonary localisation was diagnosed after 19 years of evolution of the auto-immune disease. Discovering circumstances were dyspnea and chronic cough. The radiographic and scannographic signs were diffuse because of long diagnosis delay. The underlying auto immune disease was scleroderma, rheumatoid arthritis, Sjogren's syndrome, ankylosing spondylitis, Sharp's syndrome, and multiple autoimmune syndrome. The main treatment was corticosteroids and respiratory physiotherapy. CONCLUSION: Throughout these 7 cases we discuss clinical, radiological and evolutive aspects and we focus on the need of early diagnosis for a better prognosis.
