title: Perineal endometriosis: a case report.
abstract: A previously healthy 28-year-old G1P1 Asian woman presented with a 1-year history of a painful palpable lesion arising within the left perineum. Histopathology revealed multiple endometriotic foci composed of endometrial glands and moderate dense stroma, surrounded by dense fibro-elastic tissue. This patient was diagnosed as endometriosis and the endometriotic mass was excised under local anaesthesia.
