17-year-old girl with amenorrhea, atrophied breast, hypoplastic uterus:

Here the patient is 17 years old and has amenorrhea (i.e. Primary Amenorrhea) with atrophied breast and hypoplastic uterus. Hypoplastic uterus can be seen in case of: • In klienefelter syndrome – Gonada are testis and not ovaries. The patient externally resembles a male and not female. Uterus is also absent. • In pure Gonadal dysgenesis. Uterus and cervix are present but infantile and there is some development of secondary sexual characteristics and a few episodes of bleeding (Leon speroff 8th/ed p1040) • In Androgen Insensitivity Syndrome – uterus is absent but breast development is normal, so it is also ruled out.
