OVERVIEW
Benign disease o1 the cervix and body of the uterus is extremely common. Cervical ectropion and fibroids are often present with-
out symptoms, but are also common problems encountered in almost every gynaecological outpatient clinic. Adenomyosis and.
1
Endometriosis, other important benign conditions, are considered in Chapter 10.
Benign disea.se of the uterus may conveniently be
classified in terms of the tissue of origin: the uterine
cervix, the endometrium or the myonietrium.
Epithelium: the uterine cervix
The transformation zone it. a special feature of the ecto-
iervix, and corresponds to that portion of die uterine
cervix visible during speculum examination. Within this
aone the stratified squamous epithelium of the vagina
meets the columnar epithelium of the cervical canal.
The anatomical site of the squamocolumnar junction
fluctuates under hormonal influence, and the high cell
mrnover of this tissue is important in the pathogenesis
rf cervical carcinoma, discussed in Chapter 12. The
lotumnar epithelium is normally visible with the
ipeculum during the ovulatory phase of the menstrual


c»de. during pregnancy and in women taking the corn-
wed oral contraceptive pill, in whom oestrogen levels
arc elevated. In contrast, only squamous epithelium is
visible in a postmenopausal woman not taking hor-
mone replacement therapy.
Cervical ectropion
The presence of a large area of columnar epithelium on
the ectocervix can be associated with excessive mucus
secretion, leading to a complaint of vaginal discharge.
The appearance of the cervix is termed cervical ectro-
pion or, very inappropriately, a 'cervical erosion'. The
latter term is best avoided, as it conveys quite the
wrong impression of what is really a normal phenom-
enon. Ectropion can be associated with excessive but
non-purulent vaginal discharge, as the surface area
of columnar epithelium containing mucus-secreting
glands is increased. If the discharge associated wfth
cervical ectropion becomes troublesome to the patient,
discontinuing
the
oral contraceptive pill
or,
ahenn-
tively, ablative treatment under local anaesthesia using
a thermal probe can reduce it. This treatment involves
a metal probe that heats the tissue to around 100 "C,
104 Benign disease of the uterus and cervix
destroying the epithelium to a depth of 3—1 mm. The
technique is sometimes confusingly termed 'cold coagu-
lation'to distinguish it from more destructive diathermy

or laser treatment of the cervix. A less glandular epithe-
lium regenerates after the procedure.
Cervical ectropion may also give rise to postcoital
bleeding, as fine blood vessels present within the
columnar epithelium are easily traumatized. This
symptom may be very distressing as well as embarrass-
ing, but a direct question should always be asked when
taking the gynaecological history because of its associ-
ation with cervical carcinoma. Reassurance about the
cause and treatment as described above can be given
after obtaining a normal cervical cytology result.
Nabothian follicles
Within the transformation zone of the ectocervix the
exposed columnar epithelium undergoes squamous
metaplasia. Glands contained within columnar epithe-
lium may become roofed over with squamous cells,
resulting in the formation of small (2-3 mm) mucus-
filled cysts visible on the ectocervix. These are termed
Nabothian follicles, and are of no pathological signifi-
cance, larger (up to 10mm) Nabothian follicles are
occasionally identified coincidentally during transvagi-
nal ultrasound scanning, but do not require treatment.
Endometrium
The uterine endometriurn comprises glands and
stroma with a complex architecture, including blood
vessels and nerves. As discussed in detail in Chapter 4,
during the follicular phase of the menstrual cycle,
proliferation of tissue from the basal layer occurs, fol-
lowed by secretory changes under the influence of
progesterone after ovulation and finally shedding as

progesterone levels tall, with corpus luteum regression.
Disturbances of prostaglandin biosynthesis within the
endometrium may give rise to menstrual disorders
(see Chapter 5), but the increased use of endoscopy
and ultrasound has given more specific appreciation of
visible abnormalities of the endometrium.
Endometrial polyps
Historically, a diagnosis of'dysfunctional uterine bleed-
ing was made in women with menstrual disturbance in
whom curettage provided a histologically normal sam-
ple of endometrium. In current practice, hysteroscopy
or ultrasound enables the identification of endomet-
rial polyps that may be the cause of abnormal bleeding,
especially intermenstrual bleeding. These polyps typi-
cally occur in women aged over 40 years. Intermen-
strual bleeding in younger women is more likely to be
a consequence of combined or progestogcn-only
contraceptive pill use or the wearing of an intrauterine
contraceptive device (IUCD), and is less likely to
require investigation. In perimenopausal or post-
menopausal women with abnormal bleeding, the first
priority is to exclude endometrial malignancy, but in
many patients the cause will turn out to be a benign
polyp that can be removed at hysteroscopy. Reflecting
typical clinical experience, polyps were detected by
outpatient hysteroscopy in 11 per cent of 2581 women
referred for the investigation of menstrual symptoms.
After the menopause the endometrium is normally
atrophic, but hormone replacement therapy does pro-
vide endometrial stimulation, leading to polyp forma-

tion. Women presenting special diagnostic problems
are those taking tamoxifen for the treatment of breast
cancer. This agent is a partial oestrogen agonist with
inhibitory effects on breast tissue. However, the
endometrium is stimulated, sometimes leading to
polyp formation or even endometrial hypcrplasia
and malignancy. Ultrasound assessment is difficult
because the drug affects the sonographic properties of
the inner myometrium, giving the misleading impres-
sion of a greatly thickened endometrium.
Asherman's syndrome
When [he endometrium has been damaged, in particu-
lar when it has been removed down to or beyond the
basal layer, normal regeneration does not occur, and
instead there is fibrosis and adhesion formation, termed
Asherman's syndrome. This phenomenon is exploited
therapeutically in endometrial resection, a surgical
treatment for menorrhagia in which the endometrium
is resected using a diathermy loop or is ablated with a
laser, in each case beyond the basal layer into trw
myometrium so that regeneration cannot occur. The
result is reduced, or absent, menstrual shedding.
Asherman's syndrome occurs as an adverse con-
sequence of excessive curettage, especially at the time
of evacuation of retained placental tissue after mis-
carriage or secondary postpartum haemorrhage. In a

hysteroscopic follow-up study after surgical evacu-
ation following retained placenta, the prevalence of
adhesions within the endometrial cavity was 20 per
cent, and these were strongly associated with men-
strual symptoms. Treatment options tor Asherman's
syndrome include maintaining separation of the uter-
ine walls by insertion of a large inert IUCD such as
a Lippes loop (now obsolete other than for this pur-

pose) or hysteroscopic lysis of intrauterine adhesions.
Other caLises of Asherman's syndrome relevant in
particular parts of the world are tuberculosis and
schistosomiasis.
Complications of cervical stenosis
When premalignant disease of the cervix was treated
by knife cone biopsy, rather than the currently pre-
ferred technique of diathermy loop excision (see
Chapter 12), subsequent cervical stenosis was com-
mon. This is now less commonly seen, but it may give
rise to haematometra as menstrual blood accumulates
in the endometrial cavity. Suggestive features in the
history are amenorrhoca associated with severe cycli-
cal dysrnenorrhoca-like pain, with a previous history
of cervical surgery. In postmenopausal women, cervi-
cal stenosis may give rise to pyometra, in which
accumulated secretions become a focus of infection.
Underlying malignancy may also lead to pyometra.
Treatment is by careful surgical dilatation of the cervix
and endometrial biopsy under antibiotic cover.
Finally, a cervix not completely stenosed but scarred
from previous surgery may fail to dilate during labour
cervical dystocia), necessitating Caesarean section.
Myometrium: uterine fibroids
Pathology
A fibroid is a benign tumour of uterine smooth mus-
cle, termed a leiomyoma. The gross appearance is of a
firm, whorled tumour located adjacent to and
bulging into the endometrial cavity (submucous
fibroid), centrally within the myometrium (intra-

mural fibroid), at the outer border of the
myometrium (subserosal fibroid) or attached to the
uterus by a narrow pedicle containing blood vessels
(pedunciliated fibroid) (Fig. 9.1). Fibroids can arise
separately from the uterus, especially in the broad lig-
ament, presumably from embryonal remnants. The
typical whorled appearance may be altered following
degeneration, three forms of which are recognized:
red, hyaline and cystic.
Red degeneration follows an acute disruption of the
blood supply to the fibroid during active growth, classi-
cally during pregnancy. This may present with the sud-
den onset of pain and tenderness localized to an area ot
the uterus, associated with a mild pyrexia and leukocy-
tosis. The symptoms and signs typically resolve over a
few days and surgical intervention is rarely required.
Hyaline degeneration occurs when the fibroid
more gradually outgrows its blood supply, and may
progress to centra! necrosis, leaving cystic spaces at
the centre, termed cystic degeneration. As the final
stage in the natural history, calcification of a fibroid
may be detected incidentally on an abdominal X-ray
in a postmenopausal woman. Rarely, malignant or
sarcoma to us degeneration has been said to occur, hut

P Understanding the paihophysiology
Aetiology
A range of hypotheses accounting lor the pathogenesis
o1 fibroids has been explored. The key features of jterine
leiomyomata are their occurrence during the reproductive
years, where ovarian hormone levels are high, their diverse
manifestation as either single or multiple tumours, and
the existence of racial and familial predisposition. Trie
possibility of abnormal oesirogen receptor expression has
been explored and discounted: both main progesterone
receptor subtypes are expressed similarly in myoma and
normal myometriijm. Thus myoma lissje is still influenced
by ovarian hormones. Experimentally, progesterone has
been shown to stimulate the production of both an
apoptosis-inhibiting protein and epidermal growth factor
(EGF) in cultured myoma tissue Oestradiol has the effect
of stimulating expression of the EGF receptor
Reduced expression of growth inhibitory factors such as
monocyte chemotactic protein-1 (MCP-1) may play a part in
the loss of inhibition required for fibroid growth. Treatment
by ovarian suppression (see below) is associated with an
increase in matrix metalloproleinase (WIMP) expression and
a decrease in metalioproteinase inhibitory (TIMP) activity,
which suggests that ovarian hormones have a role in

maintaining the architecture of a myoma once formed.
Cytogenetic studies have identified specific features of
uterine myoma tissue compared to normal myornetriurn
and to leiomyosarcoma. It appears that cells within srt
malignancy probably arises through a separate path-
way of chromosomal deletions (see the box above)
and the real possibility of malignant change in a
fibroid is vanishingly small.
Clinical features
Fibroids arc common, being detectable clinically in
about 20 per cent of women over 30 years of age.
Autopsy studies with systematic histology of the uterus
show a prevalence of up to 50 per cent. Risk factors for
dmkaily significant fibroids are nulliparity, obesity, a
•stive family history and African racial origin. The

Common presenting complaints are
individual myoma are monoclonal in origin, but cells
from different myomas within the same uterus are of
independent origin. It is likely that the clonal expansion of
tumour cells precedes the development of cyto-genetic
aberrations, but the latter may determine the clinical course,
depending on the extent to which control over growth is
lost Some evidence for this is provided by cytogenetic
analysis, which showed a greater proportion of karyotypic
abnormality in larger, compared to smaller, fibroids. The
most common cytogenetic aberrations detected have been
on chromosomes 12, 6, 3 and 7, a ring chromosome!, and

translocation involving chromosomes 12 and 14. Relevant
areas of chromosomes 12,6 and 7 are thought to contain
putative growth-regulating or tumour-suppressor genes. It
is not yet clear to what extent the cytogenetic features can
be correlated with the clinical picture.
Tne possibility of malignant transformation of a fibroid
to a leiomyosarcoma has traditionally been cited as a
reason to recommend surgery for fibroids, with a stated
risk of up to 05 per cent. However, current opinion is that
where a sarcoma develops in the presence of fibroids, the
association is coincidental and malignant transformation
of a fibroid is unlikely. The cytogenetic evidence gives
some basis for reassurance on this point, as the typical
findings in leiomyosarcoma tissue are of more extensive
genetic instability with frequent deletions, especially
involving chromosomes 1 and 10.

cially urinary frequency. Pain is unusual except in the
special circumstance of acute degeneration discussed
above. Menorrhagia may occur coincidentally in a
woman with fibroids; it is likely that only submucous
fibroids distorting the endomeirial cavity and increas-
ing the surface area are truly causal.
Snbfertility may result from mechanical distortion or
occlusion of the h'allopian tubes, and an endometrial
cavity grossly distorted by subrrmcous fibroids may
prevent implantation of a ferlili/ixi ovum. Once a preg-
nancy is established, however, the risk of miscarriage is
not increased. In late pregnancy, fibroids located in the
cervix or lower uterine segment maybe the cause of an

abnormal lie. After delivery, postpartum haemorrhage
may occur due to inefficient uterine contraction.

Differential diagnosis
-
Other causes of an abdominopelvic mass in a woman
in the reproductive years need to be considered. The
uterus enlarged with fibroids is typically firm in con-
trast to a uterus enlarged with a pregnancy. An ovar-
ian tumour, whether benign or malignant, primary or
secondary, may enlarge to occupy the pelvis and be
clinically difficult to differentiate from a uterine
fibroid. Leiomyosarcomas typically present with a
history of a rapidly enlarging abdominopelvic mass.
There may be less mobility of the uterus than
expected with a fibroid and general signs of cachexia.
Investigations
Often the clinical features alone will be sufficient to
establish the diagnosis. A haemoglobin concentration
will help to indicate anaemia if there is clinically sig-
nificant menorrhagia. Ultrasonography is useful to
distinguish a uterine from an ovarian mass. Imaging
of the renal tract may be helpful in the presence of a
large fibroid to exclude hydronephrosis due to pres-
sure from the mass on (he ureters. Clinical suspicion
of sarcoma will be an indication for needle biopsy or,
more likely, urgent laparotomy.
Treatment

Conservative management is appropriate where
asymptomatic fibroids are detected incidentally. It may
be useful LO establish the growth rate of the fibroids by
repeat clinical examination or ultrasound after a 6-12-
month interval. Where treatment is required, the only
t practical currently available medical treatment is ovar-
nn suppression using a gonadof rophin-releasing hor-
mone (GnRH) agonist. Unfortunately, while very
effective in shrinking fibroids, when ovarian function
returns, the fibroids regrow to their previous dimen-
sions. Mifepristone (an aniiprogestogen) has been
shown to be effective in shrinking fibroids at a low dose,
but is not available for use in this indication. The opti-
mal dose, duration of treatment and long-term effects
Tave yet to be established.

within the endometrial cavity. (Kindly supplied by
Mr ED Alexopoulos.)
The choice of surgical treatment is determined by
the presenting complaint and the patient's aspirations
for menstrual function and fertility. Menorrhagia asso-
ciated with a submucous fibroid or fibroid polyp (Fig.
9.2) may be treated by hysteroscopic resection. Where a
bulky fibroid uterus causes pressure symptoms, the
options are myomectomy with uterine conservation,
or hystereclomy. Myomectomy will be the preferred
option where preservation of fertility is required, but
care must be taken in the management of a subsequent
pregnancy, as the uterus may be predisposed to rup-
ture. It is traditionally held that uterine rupture during

pregnancy is more likely wben the endometrial cavity
has been entered during myomectomy, but, not sur-
prisingly, there are few data to confirm or refute this. In
any event, the decision to undertake myomectomy in a
woman who desires future fertility needs to be care-
fully considered and the benefits and risks fully dis-
cussed with the patient. An important point for ihe
preoperative discussion is that there is a small but sig-
nificant risk of uncontrolled bleeding during myomec-
lotny, which could lead to the need for hysterectomy.
Hysterectomy and myomectomy can be facilitated
by GnRH agonisi pretreatment over a 2-month period
to reduce the bulk and vascularity of the fibroids.
Useful benefits of this approach are to enable a
Pfannensteil (low transverse) rather than a midline
abdominal incision, or to facilitate vaginal rather than
abdominal hysterectomy, both of which are conducive
to more rapid recovery and fewer postoperative com-
plications. A technical problem with myomectomy
after GnRH agonist pre-treatment is that die tissue
planes around the fibroid are less easily defined, but
on the positive side, blood loss and the likely need for
transfusion are reduced.

Management
Pelvic exam in a tin n often reveals an enlarged and ten-
der uterus. If the woman has no symptoms and the
uterus is not enlarged, no Treatment is indicated. If

the woman is symptomatic, hysterectomy is usually
the preferred treatment, since adenomyosis does not
respond well to hormonal treatment.
New developments
Endoscopic surgical treatments for fibroids have proved
disappointing: myolysis using a diathermy needle to destroy
the tissue is followed Oy intense adhesion formation. Given
the requirement for a substantial blood supply to support
growth, interruption of the arterial supply to the tumour is a
theoretically attractive concept. In practice, this is feasible
by the radiological technique of percutaneous selective
cathetenzation o1 the uterine arteries. Microparticles are
released into the vessels, causing occlusion of both uterine
arteries Sufficient collateral circulation is present from the
ovarian arteries to sustain normal uterine metabolic require-
ments, and women experience a substantial reduction in
fibroid bulk, together with improvement in menstrual symp-
toms over the following 6 months. Currently available fol-
low-up data suggest that the symptomatic improvement is
sustained. Figures 9.3a and b show contrast-en ha iced
magnetic resonance imaging (MRI) of a fibroid uterus
before and after embolization of the uterine arteries.

For this reason many ini'ejiig-ilors ^vould
lh<: bi'nefil of any form of medial or surgical treat-
ment in such cases. Clearly, if, aparl fiom hei subfer-
tihtv the patient albo has symptoms s>&ocLiled i^illl
endomelnLnis, appropriate therapy is indicated. How-
ever, il is accepted lhal endometriosis is a disease that
tends to peisist and often progress i\uh lime. There is
iin argument that oflering therapy al sin early .siage
m,iy prevent further progression nf the Disease, the
end result ot which may well be mechanical disrup-
tion
to
tubal-ov^rian
funclkm.
I'Lir
these
reasons,
endometriosis involving the posterior aspect of the
ovai v and the ovarian fossa is often treated a! an eariv
stage, whereas endometrLosis otXurring only on the
ulerobacr^l
ligamenls

may
well
be
left

Froni the balance ot evidence, cundusians have

This

be brought inly question following publication of the

With
regard
to hormonal Iherapy, the evidence is very clear thiit
this treatment doi'i no! rmpiove subsequent fertility.

Treatment
Patients with endomelriosisare often difficult to treat,
nul on!;, from ii physical poinl of view, but also often
because of diboaated psychological issues. For iume
patients the label of eiulomctnoiis in itself may create
ill own problems, since it is known to be a recurrent
disorder throughout the whole of reproductive life.
Whilst there is no ilandard lormula for treatment, nor
indeed a cure, i( is iniportanl to tailor treatment for
rhe individual according to her age, symptoms, extent
ol' die diseuse and her desire I'oi future childbearing.
Problems also arise when minimal endometiiosis is
detected in a patient presenting wiill pain and there is
veal uncertainty a& to whether the condition ib coinci-
dental 01 causal. In ibii bituanon a kill explanation of
llu: j&bociated diagnostic uncertainty LS required.
Drug
Analgesics
Non-fitffrttidal anti-inflammatory drugs \NSAIDs) are
potent anal&eski and are very helpful in reducing the
.seventy of dysmenorrhoea and pelvic pain HOIM^IT,
thev have no specific impacl vn ihe disease and its
nrogreibiim and hence their use is for svmplom con-
trol. There may be additional benefit in combining
thost agents with paracetamol or codeine, so as to avoid
the main adverse effect of ViAIUs which is gabtrom-
testmal upset.
