A 47-year-old woman with 4 episodes of right pneumothorax related to onset of menstruation was reported. A month ago, she was undergone breast conserving resection for breast cancer. She had recurrent right pneumothorax a month later and operation was performed. Thoracoscopy revealed the presence of multiple fenestrations in the right diaphragm. Thoracoscopic partial resection of the diaphragm was performed. Histopathological findings of the lesion showed spindle cells with hemosiderosis. Immunohistochemistry showed that spindle cells were estrogen receptor (ER) positive and progesterone receptor (PgR) positive, compatible with endometriosis. She was treated by tamoxifen and goserelin acetate for breast cancer and endometriosis. Two years later, gonadotropin releasing hormone (GnRH) analogue was converted from goserelin acetate to leuprorelin acetate. She was diagnosed as having recurrence of right pneumothorax 17 months later and was treated with a chest tube. Additionally, GnRH analogue was re-converted to goserelin acetate. Since then, she has been asymptomatic free for 18 months. A catamenial pneumothorax is rare disease with difficulty of diagnosis and treatment We herein report a case of the disease that was treated successfully by goserelin acetate.

Catamenial pneumothorax is defined as spontaneous pneumothoraces occurring within 72 h before or after onset of menstruation. It is rare but clinical index of suspicion should be high in ovulating women with spontaneous pneumothoraces. The mechanism is unclear but is thought to involve pre-existing or acquired diaphragmatic defects and endometrial implants. Traditional therapy involving hormonal treatment or surgical pleurodesis alone is associated with high rates of recurrence. A series of four patients with catamenial pneumothorax managed at our institution is presented to highlight the condition to various surgical specialties to whom it may present, and to emphasise the importance of both surgical and hormonal interventions in preventing recurrence. Each patient underwent video-assisted thoracoscopic inspection of the diaphragm, mechanical pleurodesis and, most importantly, repair of diaphragmatic defects with an artificial mesh. Surgical treatment was strictly followed by a course of gonadotrophin-releasing hormone analogue therapy in three patients, with no recurrence to date (longest follow-up 45 months). The fourth patient suffered a postoperative recurrence when hormonal treatment was delayed for 6 weeks, stressing the importance of hormonal treatment in conjunction with surgery.

We report a case of recurring catamenial pneumothorax with concurrent pelvic endometriosis. Thoracoscopy revealed a blue-like lesion on top of the dome of the right hemidiaphragm. Microscopic examination of biopsy specimens showed endometriosis. The patient was treated with a Gn-RH analogue and remains well without further evidence of pneumothorax after six months.
