METHODS
Case report.


METHODS
Tertiary gynecologic center.


METHODS
A 13-year-old girl presenting with profuse uterine bleeding.


METHODS
Dysfunctional uterine bleeding was diagnosed, and pharmacologic therapy with a monophasic oral contraceptive (OC) pill was introduced.


METHODS
A large decidual cast occurred during treatment.


RESULTS
After finishing therapy with OC followed by three cycles of cyclic progestogen, the patient experienced regular menses.
