Mayer-Rokitansky-Kuster-Hauser Syndrome (MRKH) is a rare disease characterized by total or partial vagina agenesis, karyotype 46, XX with normal secondary sexual characters. Still, it is the second leading cause of primary amenorrhea. The absence of obvious signs and symptoms often causes the syndrome to be diagnosed only after puberty. The case presented here highlights exactly this difficulty of early diagnosis, which meets the objective of the study, and is precisely to provide reliable material that facilitates the diagnosis and management of patients with MRKH syndrome.
