title: [Thoracic endometriosis with aspecific manifestation].
abstract: Endometriosis is a common disease, especially in subfertile women. The most common location is in the pelvis, but extragenital locations are also possible. This far less common condition has been described in almost all tissues in the body. Symptoms occurring cyclically are characteristic of endometriosis.
  
  
  
  A 37-year-old woman was discovered by chance to have ascites and pleural effusion. She had no symptoms of this. Thoracoscopy showed an image consistent with thoracic endometriosis. After initial drug therapy was unsuccessful, surgical intervention was performed.
  
  
  
  Thoracic endometriosis is a rare disease, in which the cyclical nature of the symptoms often leads to correct diagnosis. Drug therapy is the preferred treatment for patients.
