PREMENARCHAL VAGINAL
BLEEDING
An  8-year-old  girl    is  brought by  her mother  to  the gynecologist’s  office
because of  vaginal bleeding    for two weeks.  The girl    states  that    she has not
taken   any medication  and gives   no  history suggestive  of  sexual  abuse.  She
does    not complain    of  headache    or  visual  disturbance and has been    doing
well    in  school. On  physical    examination she is  normal  for her age without
pubertal    changes,    and pelvic  examination under   sedation    reveals a   vaginal
foreign body.Premenarchal    bleeding    is  bleeding    that    occurs  before  menarche    (the    average age
at  menarche    is  age 12).    Possible    causes  include ingestion   of  estrogen    medication,
a   foreign body    that    irritates   the vaginal lining, a   cancer  of  the vagina  or  of  the
cervix  (sarcoma    botryoides),    a   tumor   of  the pituitary   or  adrenal gland,  an  ovarian
tumor,  sexual  abuse,  or  idiopathic  precocious  puberty.    The most    common  cause
of  premenarchal    bleeding    is  a   foreign body.
Diagnosis and Management.
Pelvic  examination.    The patient who complains   of  premenarchal    bleeding
should  have    a   pelvic  examination under   sedation.   In  this    examination,
evidence    of  a   foreign body,   sexual  abuse,  or  tumor   is  looked  for.    Sarcoma
botryoides  typically   looks   like    grapes  arising from    the vaginal lining  or  from
the cervix.
Imaging study.  CT  scan    or  MRI scan    of  the pituitary,  abdomen,    and pelvis
