We present a case of a 30-year-old primigravida, at 38-week gestation, who had a posterior classical uterine incision due to a huge anterior wall leiomyoma associated with uterine torsion and breech presentation. The rarity of this type of uterine incision, the size of the uterine myoma and the uterine torsion prompted this case report. During caesarean section, the diagnoses of uterine torsion and a huge anterior wall leiomyoma were made. She had safe delivery of the fetus through a posterior classical caesarean section. The patient had an uneventful post-operative period and was discharged home with her baby on the fourth post-operative day.
