A Thoracic Endometriosis-Related Catamenial Hemopneumothorax in a Woman With Premature Ovarian Failure.

Endometriosis is the presence of endometrial glands and stroma outside the uterine cavity. It is usually confined to the pelvis, particularly the ovaries, cul-de-sac, broad ligaments, and uterosacral ligaments, but it can also expand outside the pelvis. The thorax is among the common extrapelvic locations. Thoracic endometriosis syndrome (TES) is a rare disorder characterized by the presence of functioning endometrial tissue in the pleura, lung parenchyma, and airways. This report presents a case of a young female patient with advanced endometriosis and premature ovarian failure who was admitted with dyspnea that turned to be due to a rare endometriosis-related complication.
