[Multicystic lung revealing a Sjogren's syndrome]

The Sjogren's syndrome is a chronic inflammatory autoimmune disease that affects primarily the exocrine glands, but can affect other organs particularly the lungs. Cystic lung disease is very significant but exceptionally recounted in the literature. We report the case of a patient, 54 years old, whose disease was discovered incidentally after a routine chest radiograph. The diagnosis of cystic lung revealing a primary Sjogren's syndrome was held before a group of radio-clinical, immunological and histological arguments. Through our observation, the diagnosis of Sjogren's syndrome should be included in the list of diagnoses to raise in a multicystic lung.
