Rupture of unscarred uterus during the second trimester is rare. A case of ruptured uterus in a multiparous woman is presented. To our knowledge, this might be the first reported case in the English literature of uterine rupture during second trimester termination of pregnancy using ethacridine lactate. This case is also rare as uterine rupture is presented with an insidious course rather than acute, thus delaying the diagnosis.
