Abstract:
Thoracic endometriosis-related pneumothorax (TERP) or thoracic endometriosis syndrome (TES) usually occurs in women of childbearing age and affects the right thorax. Menopausal and left-sided cases are rare. A case of left-sided TERP in a postmenopausal woman after adjuvant endocrine therapy for breast cancer is reported. A 51-year-old woman underwent video-assisted thoracic surgery for recurrent left pneumothorax. Immunohistological examination of the resected specimen from the apical bleb and a diaphragmatic blueberry spot demonstrated thoracic endometriosis. Even in the case of a left-sided pneumothorax in a menopausal woman, clinicians should be aware of the possibility of TERP.

Endoscopic Studies II: Thoracocentesis
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...
