Abnormal uterine bleeding: an insidious presentation.

An adolescent was referred to the emergency department due to abnormal uterine haemorrhages in the previous 2 months, associated with dizziness in the last month. At observation, she was haemodynamically stable, with good clinical impression, but evident mucocutaneous pallor. Full blood count confirmed a severe anaemia (haemoglobin 47 g/L). She received red blood cell transfusion (10 mL/kg) and started oral oestradiol. She was discharged, with oral oestradiol and oral iron supplementation. Two weeks later, she started treatment with oestradiol and progestin. The patient had a good recovery, without new similar episodes.
