Sloughing off of a cervical myoma after cesarean section: a case report.

Background: Occasionally a submucous myoma is sloughed off during the puerperium, but it is seldom that the initial location of the myoma is identified before its expulsion.

Methods: A 32-year-old, nulliparous woman with a cervical myoma underwent an elective cesarean section at 37 weeks. At surgery a cervical myoma was identified as not endophytic to the intrauterine cavity but exophytic to the uterine exterior and was left without any intervention. Part of the cervical myoma was sloughed off into the vagina after 16 days, and an abdominal myomectomy was performed for a refractory infection.

Conclusions: Comparison with analogous cases following intervention indicates that myoma degeneration due to blood supply depletion, uterine contractions and endometrial sparseness must be important factors in this phenomenon. When these conditions are met, a shallow, intramural myoma could be sloughed off in the puerperium.
