Spontaneous uterine rupture during the first trimester of a partial molar pregnancy in a scar uterus: A rare case report

INTRODUCTION: Spontaneous uterine rupture in the first trimester is a redoubtable obstetric emergency that carries a high risk for both mother and fetus. CASES PRESENTATION: We present the case of a spontaneous uterine rupture in a patient with a scarred uterus at 9 weeks' gestation treated by laparotomy in emergency obstetrical department of Ibn Rochd University Hospital of Casablanca; whose histological examination of the removed material found a partial mole. CLINICAL DISCUSSION: Spontaneous uterine rupture in the first trimester is rare and usually occurs in a scarred or malformed uterus. Clinicians should consider this diagnosis in the presence of an acute abdominal pain in early pregnancy with or without first trimester metrorrhagia. CONCLUSION: Since the rate of uterine surgeries is increasing, it is necessary to highlight the risk of uterine rupture occurring early in order to improve their management. Molar pregnancy is a factor of fragility of the uterine wall and uterine rupture must be suspected in any molar pregnancy associated with a hemoperitoneum.
