Abstract:
Menorrhagia is a common gynecological symptom. In adolescents, the cause is generally
dysfunctional uterine bleeding. Menorrhagia may also be due to undiagnosed coagulation
defects, endocrine disorders, gynecological abnormalities of the uterus, or other systemic
disorders. Menorrhagia may be the only clinical manifestation of an inherited bleeding disorder.
We report a case of inherited hypoprothrombinemia (factor II deficiency), a rare bleeding
disorder as the cause of life‐threatening menorrhagia. In the absence of a readily identifiable
cause, all adolescents with menorrhagia should be examined for bleeding disorders.
