Does menstrual flow exclude hematometra? A rare case of uterine anomaly presenting with anorectal malformation.

Hematometra, which is defined as accumulation of menstrual secretions in the uterine cavity, may not be diagnosed until the maturating adolescent fails to menstruate. Clinically, a lower abdominal mass and periodic abdominal pain may develop in these children after puberty. Here, a 13-year-old girl with menstrual flow who presented with symptoms of genital outflow tract obstruction is described.
