Recurrent Hemothorax and Hemoperitoneum in Endometriosis: A Case Report.

Extra-pelvic endometriosis, defined as the presence of endometrial tissue or stroma outside of the pelvic cavity, is a rare cause of hemothorax and hemoperitoneum. Here, we present a case of a 34-year-old woman with a history of endometriosis who experienced recurrent, cyclical episodes of hemorrhagic pleural effusions and ascites. Despite multiple surgeries to address the ectopic endometrial implants, her symptoms persisted for years without definitive resolution, illustrating the challenges of treatment even after the diagnosis has been established. This case highlights the rare manifestations of extra-pelvic endometriosis and the long-term complications they may pose. Early recognition and intervention are crucial to prevent chronic sequelae and reduce morbidity.
