Recurrent pleural effusion secondary to endometriosis: a rare malady

Thoracic endometriosis is a rare entity, wherein thoracic endometrial tissue deposition occurs. Recurrent pleural effusion is one of its manifestations. Diagnosis and treatment are often challenging, owing to the rarity of the condition and recurrences. We present an interesting case of a young woman of childbearing age who presented with recurrent haemorrhagic pleural effusion. She was referred to our centre after her initial video-assisted thoracoscopic biopsy was inconclusive. She was re-evaluated, and video-assisted thoracoscopic biopsy confirmed thoracic endometriosis. She underwent pleurodesis two times and currently on hormonal treatment, maintaining well.
