We present a woman who presented with an umbilical mass which bleeds cyclically. The mass developed following abdominal myomectomy and concurrent repair of umbilical hernia during menstruation. She had excision biopsy of the umbilical mass and umbilical reconstruction; histological examination confirmed endometriosis. The hihgpoints of this presentation are to emphasize the need to avoid abdominal myomectomy during menstruation and discourage concurrent surgical procedures because these increase the risk of endometriosis after the procedure.enUmbilical endometriosisMyomectomyHerniorraphyArticle
