Recurrent epistaxis in a 15 year old female the most common cause is -

As such this answer is not given anywhere but we can come to the correct answer by exclusion. Option “a” is Juvenile nasopharyngeal fibroma. It is seen in adolescent males and is therefore the most common cause of recurrent epistaxis in males and not in females. Ref. Dhingra 6/e, p 346 Option “b” is Rhinosporidiosis is a cause of epistaxis but usually occurs in young males from India. Ref. Turner 10/e, p 61 Option “c” is Foreign body which is a cause of epistaxis in children and is not commonly seen in 15 years of age. So we are left with hematopoietic disorder which can be seen in a 15 years old female.
