Abstract
A 47-year-old woman was admitted with recurrent pneumothorax. Preoperative chest computed
tomography (CT) showed multiple lung nodules and cysts bilaterally. She had undergone
enucleatic myomectomy 12 years earlier. Video-associated thoracoscopic biopsy was
performed. Histopathologically, there were bulla-like dilated cystic changes, the
walls of which showed spindle cell proliferation, causing pneumothorax. Hormone therapy
was started after benign metastasizing leiomyoma resection; pneumothorax has not recurred
in 7 months. Multiple residual lung nodules have decreased or disappeared on CT.
