This case report describes a 40-year-old woman who underwent surgery for recurrent pneumothorax in whom a right diaphragmatic defect was diagnosed as ectopic endometriosis, but persistent postoperative air leakage led to further evaluation. Chest computed tomography found a 5-mm ground-glass opacity in the right S3 region, and 10 days later she had curative surgery addressing both pneumothorax and the lung lesion. The tumor was diagnosed as bronchioloalveolar carcinoma, and the authors report that no additional endometriosis was identified; the limitation is that this is a single-patient case report. Relevance to endometriosis: the report involves diaphragmatic ectopic endometriosis initially suspected as the cause of her pneumothorax, though the eventual lung cancer diagnosis was incidental.

Abstract

A 40-year-old female patient underwent surgery at our hospital for recurrent pneumothorax. A defect on the right diaphragm was diagnosed as ectopic endometriosis. However, air leakage continued 2 days after surgery. Chest computed tomography identified a 5-mm ground glass opacity in the right S3 field, suggestive of lung cancer. Ten days after the initial surgery, she underwent curative surgery for both pneumothorax and the lung tumor. The tumor was diagnosed as bronchioloalveolar carcinoma, but no other endometriosis was identified. The patient has remained well with no recurrence of lung cancer or pneumothorax since the second surgery.
