They may contain tissues from all three germ layers, though ectodermal tissue is most commonly represented. MCTs are generally asymptomatic and do not tend to recur after resection. Complications of MCTs include ovarian torsion, infection, malignant transformation, and rupture. The rate of malignant transformation is estimated to be 0.2–2%, and over 80% of tumors that become malignant are squamous cell carcinomas. Risk factors for malignant transformation include elevated CA-125 levels, older age, and large tumor size. Rupture is generally either spontaneous or associated with torsion. Very rarely, however, rupture may be a consequence of blunt abdominal trauma. This may result in considerable concern for a ruptured viscus or hemorrhage.We report what is to authors' knowledge the third case of traumatic rupture of MCT, and the first in a child....
