A right pneumothorax in a 38-year-old woman recurred premenstrually, with thoracotomy revealing microscopic diaphragmatic endometriosis and hemosiderine crystals but no defect.

This case report describes a 38-year-old woman presenting with recurrent right-sided pneumothorax episodes occurring shortly before her menstrual period over a two-year span. Surgical exploration via thoracotomy revealed a 10mm solid black mass on the right diaphragmatic dome, which microscopic analysis identified as endometrial tissue containing hemosiderin crystals, despite the absence of visible lung surface abnormalities or diaphragmatic defects. The authors note that this represents the first documented instance in Japan linking catamenial pneumothorax to thoracic endometriosis. This paper is centrally about endometriosis — specifically describing diaphragmatic endometriosis causing catamenial pneumothorax.

A case of catamenial pneumothorax with endometriosis of the diaphragma 1978 Volume 16 Issue 1 Pages 59-63 Details Abstract A 38. year-old married woman was admitted with right pneumothorax. During the preceeding two years she had experienced several similar episodes, usually occuring shortly before her menstrual period. A thoracotomy was performed on 17 August 1976. No gross pathological findings were noted on the lung surface. On the right diaphragmatic dome we found a solid black mass, 10mm in diameter, surrounded by many petechia. It was diagnosed microscopically as endometrial tissue accompanied by hemosiderine crystals. We could not find any diaphragmatic defect in this case. This is the first reported case of catamenial pneumothorax associated with thoracic endometriosis in Japan.
