Extraperitoneal endometriosis with catamenial pneumothoraces: a review of the literature.
OBJECTIVE
To present a case of recurrent catamenial pneumothorax and diaphragmatic endometriosis that was managed thoracoscopically. A review of the literature is also presented.


METHODS
A-28-year-old woman presented with bloody stools, chronic constipation, and chest pain. A review of systems was positive for monthly chest pain associated with her menses. A preoperative chest x-ray revealed a right pneumothorax. Colonoscopy revealed biopsy proven endometriosis of the sigmoid colon. A pelvic computed tomography scan revealed bilateral complex, cystic and solid adenexal lesions.


RESULTS
A right thoracoscopy was performed. A lesion on the right hemidiaphragm was excised and confirmed to be endometriosis. A wedge section of lung tissue containing a bleb was resected and also contained endometriosis. Three months later, the patient underwent laparoscopic excision of her pelvic endometriosis, including a low anterior rectal resection. Five months later, she presented again with right-sided chest pain. A thoracoscopic right total pleurectomy was performed for recurrent pneumothorax.


CONCLUSIONS
Pullmonary endometriosis may present as chest pain, shortness of breath, or hemoptysis associated with menstrual cycles. This case emphasizes the importance of a careful review of systems in patients with known endometriosis. Management now includes an endoscopic alternative and all of its known benefits.
