Catamenial pneumothorax

Discussion:

The patient elected for surgery to decrease risk of recurrent pneumothorax. A right VATS, right upper lobe wedge resection, right partial diaphragmatic excision, chemical (doxycycline) and mechanical pleurodesis were performed. Intraoperatively, the patient was noted to have chocolate-colored nodules of the parietal pleura, and right hemidiaphragm, and scarring of the apical segment of the right upper lobe. These specimens were sent to pathology, and presence of thoracic endometriosis was confirmed on histology. The patient was discharged with oral contraceptive pills.
